LORD BROWNE-WILKINSON. My Lords, the underlying subject matter of these tax appeals is the correct basis for valuing benefits in kind received by the taxpayers who are schoolmasters. However in the circumstances which I will relate, the appeals have also raised two questions of much wider importance. The first is whether in construing ambiguous or obscure statutory provisions your Lordships should relax the historic rule that the courts must not look at the Parliamentary history of legislation or Hansard for the purpose of construing such legislation. The second is whether, if reference to such materials would otherwise be appropriate, it would contravene article 9 of the Bill of Rights 1689 or Parliamentary privilege so to do.
The facts are fully set out in the judgments of Vinelott J.  1 W.L.R. 204 at first instance and of the Court of Appeal  Ch. 203. Shortly stated, the taxpayers are nine masters and the bursar employed by Malvern College (“the school”). For many years the school has run a concessionary scheme under which members of the staff are entitled to have their children educated at the school on payment of only one-fifth of the sum charged to members of the public. In the relevant tax years, 1983–84, 1984–85 and 1985–86, children of one or more of the taxpayers were educated at the school on payment of the concessionary fees only. It is common ground that the concessionary fees more than covered the additional cost to the school of educating the taxpayers' children.
The school had a capacity to accept 625 boys but in the relevant years the school was not full to capacity. The admission of the taxpayers' children to the school therefore did not involve the school in losing full fees which would otherwise have been paid by members of the public for the places which the taxpayers' children occupied.
It is common ground that the education of the children at reduced fees was a taxable benefit under section 61(1) of the Finance Act 1976 which provides:
“[Subject to section 63(A) ( b)] where in any year a person is employed in director's or higher-paid employment and — ( a) by reason of his employment there is provided for him, or for others being members of his family or household, any benefit to which this section applies; and ( b)the cost of providing the benefit is not (apart from this section) chargeable to tax as his income, there is to be treated as emoluments of the employment, and accordingly chargeable to income tax under Schedule E, an amount equal to whatever is the cash equivalent of the benefit.”
The crucial question relates to the amount which is to be treated as an emolument, i.e., what is “the cash equivalent of the benefit.” These words are defined by section 63(1) and (2) as follows:
“(1) The cash equivalent of any benefit chargeable to tax under section 61 above is an amount equal to the cost of the benefit, less so much (if any) of it as is made good by the employee to those providing the benefit. (2) Subject to the following subsections, the cost of a benefit is the amount of any expense incurred in or in connection with its provision, and (here and in those subsections) includes a proper proportion of any expense relating partly to the benefit and partly to other matters.”
The taxpayers contend that the only expense incurred by the school “in or in connection” with the education of their children is the additional, or marginal, cost to the school. The school was, in any event, up and running so as to provide its educational facilities for 625 boys. All the costs of running the school (staff salaries, provision of buildings and grounds etc.) would have had to be incurred in any event: the admission of the taxpayers' children did not increase these basic expenses in any way. The only expense attributable to the education of the taxpayers' children (additional food, laundry, stationery etc.) was fully covered by the one-fifth concessionary fee paid by the taxpayers. Therefore “the cash equivalent of the benefit” is nil.
The revenue on the other hand contend that the “expense incurred in or in connection with” the provision of education for the children of the taxpayers was exactly the same as the expense incurred in or in connection with the education of all other pupils at the school and accordingly the expense of educating any one child is a proportionate part of the cost of running the whole school.
These provisions regulate the taxation of all benefits in kind. As Nicholls L.J. pointed out in the Court of Appeal, for present purposes such benefits can be of two kinds. First, the benefit may be of a kind bought in from outside the employer's business, such as a car or medical insurance (“external benefits”). Second, the benefit may consist of the enjoyment by the employee of services or facilities which it is part of the employer's business to sell to the public, for example concessionary travel for railway or airline employees or concessionary education for the children of schoolteachers (“in-house benefits”). In both cases the benefit falls to be quantified by reference to the expense of providing the benefit. In the case of external benefits this does not normally raise any major problems because such cost is an isolated expenditure. But in the case of in-house benefits there is an obvious problem, since the employer is, for the purpose of selling the facility to the public, incurring the cost of running the train, airline or school the use of which is provided on a concessionary basis to the employee. What then is the cost to the employer of providing the in-house benefit for the employee? Is it only the additional or marginal cost to the employer providing the service for the employee, or is it a proportionate part of the total costs incurred by the employer in providing the facility to be used both by the public and by the employee?
The special commissioner held in favour of the taxpayers. That decision was reversed by Vinelott J.  1 W.L.R. 204, whose decision was affirmed by the Court of Appeal  Ch. 203. The taxpayers appeal to your Lordships' House.
The case was originally argued before your Lordships without reference to any Parliamentary proceedings. After the conclusion of the first hearing, it came to your Lordships' attention that an examination of the proceedings in Parliament in 1976 which lead to the enactment of sections 61 and 63 might give a clear indication which of the two rival contentions represented the intention of Parliament in using the statutory words. Your Lordships then invited the parties to consider whether they wished to present further argument on the question whether it was appropriate for the House (under Practice Statement (Judicial Precedent)  1 W.L.R. 1234) to depart from previous authority of this House which forbids reference to such material in construing statutory provisions and, if so, what guidance such material provided in deciding the present appeal. The taxpayers indicated that they wished to present further argument on these points. The case was listed for rehearing before a committee of seven members not all of whom sat on the original committee.
At the start of the further hearing, the Attorney-General, who appeared for the Crown, drew our attention to a letter addressed to him by the Clerk of the House of Commons suggesting that any reference to Hansard for the purpose of construing the Act might breach the privileges of that House. Until 31 October 1980, the House of Commons took the view that any reference to Hansard in court proceedings would constitute a breach of its privileges and required a petition for leave to use Hansard to be presented in each case. On 31 October 1980 the House of Commons resolved as follows:
“That this House, while re-affirming the status of proceedings in Parliament confirmed by article 9 of the Bill of Rights, gives leave for reference to be made in future court proceedings to the Official Report of Debates and to the published Reports and evidence of Committees in any case in which, under the practice of the House, it is required that a petition for leave should be presented and that the practice of presenting petitions for leave to refer to Parliamentary papers be discontinued.”
The letter of 5 June 1992 from the Clerk of the House of Commons starts by saying, “My attention has been drawn to the fact that the House of Lords may be asked to hear argument in this case based on the meaning or significance of words spoken during proceedings on a Bill in the House of Commons.” The letter then sets out the text of the resolution of 31 October 1980, and continues:
“In my opinion, the use proposed for the Official Report of Debates in this case is beyond the meaning of the ‘reference’ contemplated in the Resolution of October 1980. If a court were minded in particular circumstances to permit the questioning of the proceedings of the House in the way proposed, it would be proper for the leave of the House to be sought first by way of petition so that, if leave were granted, no question would arise of the House regarding its privileges as having been breached.”
The reference in that letter to “questioning” the proceedings of the House of Commons plainly raised the issue whether the proposed use of Parliamentary materials without the leave of the House of Commons would breach article 9 of the Bill of Rights 1689 which provides:
“That the freedome of speech and debates or proceedings in Parlyament ought not to be impeached or questioned in any court or place out of Parlyament.”
The Attorney-General, while submitting that such use of Parliamentary material would breach article 9, accepted that it was for the courts to determine the legal meaning and effect of article 9. However, the Attorney-General warned your Lordships that, even if reference in this case to Parliamentary materials did not infringe article 9, the House of Commons might take the view the House enjoyed some wider privilege which we would be infringing and might well regret that its views on the point had not been sought before a decision was reached by your Lordships. Whilst strictly maintaining the privileges of the House of Commons, the Attorney-General used the Parliamentary materials in this case as an illustration of the dangers of so doing. Moreover, in order to assist us, whilst still maintaining the privileges of the House of Commons, he made submissions as to the effect of such material on the construction of section 63 if, contrary to his contentions and advice, we decided this appeal with the assistance of such material.
In the result, the following issues arise. 1. Should the existing rule prohibiting any reference to Hansard in construing legislation be relaxed and, if so, to what extent? 2. If so, does this case fall within the category of cases where reference to Parliamentary proceedings should be permitted? 3. If reference to Parliamentary proceedings is permissible, what is the true construction of the statutory provisions? 4. If reference to the Parliamentary proceedings is not permissible, what is the true construction of the statutory provisions? 5. If the outcome of this case depends upon whether or not reference is made to Hansard, how should the matter proceed in the face of the warnings of the Attorney-General that such references might constitute a breach of parliamentary privilege?
I will consider these issues in turn, but first I must set out the Parliamentary history of sections 61 and 63 by reference to which the case was argued before us.
The Parliamentary material
For reasons which will appear it is necessary first to refer to the legislation affecting the taxation of benefits in kind before 1975. Under the Finance Act 1948, section 39(1), directors and employees of bodies corporate earning more than £2,000 per annum were taxed under Schedule E on certain benefits in kind. The amount charged was the expense incurred by the body corporate “in or in connection with the provision” of the benefit in kind. By section 39(6) it was provided that references to expenses “incurred in or in connection with any matter includes a reference to a proper proportion of any expense incurred partly in or in connection with that matter.” Employment by a school or charitable organisation was expressly excluded from the charge: sections 41(5) and 44. These provisions were re-enacted in the Income and Corporation Taxes Act 1970.
Those provisions covered in-house benefits as well as external benefits. We were told that after 1948 the revenue sought to tax at least two categories of employees in receipt of in-house benefits. Higher paid employees of the railways enjoy free or concessionary travel on the railways. The revenue reached an agreement that such employees should be taxed on 20 per cent. (later 25 per cent.) of the full fare. Airline employees also enjoy concessionary travel. We were told that in the 1960s the revenue sought to tax such employees on that benefit on the basis of the average cost to the airline of providing a seat, not merely on the marginal cost. The tax commissioners rejected such claim: the revenue did not appeal. Therefore in practice from 1948 to 1975 the revenue did not seek to extract tax on the basis of the average cost to the employer of providing in-house benefits.
In 1975 the Government proposed a new tax on vouchers provided by an employer to his employees which could be exchanged for goods or services. Clause 33(1) of the Finance (No. 2) Bill 1975 provided that the employee was to be treated, on receipt of a voucher, as having received an emolument from his employment of an amount “equal to the expense incurred by the person providing the voucher in or in connection with the provision of the voucher and the money, goods or services for which it is capable of being exchanged.” The statutory wording of the Bill was therefore similar to that in the Act of 1948 and in section 63(2) of the Finance Act 1976. On 1 July 1975 in the Standing Committee on the Bill (Standing Committee H), the Financial Secretary was asked about the impact of the clause on railwaymen. He gave the following answer (Hansard, column 666):
“Similarly, the railwayman travelling on his normal voucher will not be taxable either. The clause deals with the situation where a number of firms produce incentives of various kinds. In one or two instances, there is likely to be some liability concerning rail vouchers of a special kind, but in general, the position is as I have said and they will not be taxable.”
He was then asked to explain why they would not be taxable and replied:
“Perhaps I can make clear why there is no taxable benefit in kind, because the provision of the service that he provides falls upon the employer. Clearly, the railways will run in precisely the same way whether the railwaymen use this facility or not, so there is no extra charge to the Railways Board itself, therefore there would be no taxable benefits.”
Later he explained that by the words “no extra charge” he meant “no extra cost.” Clause 33(1) of the Bill was enacted as section 36(1) of the Finance (No. 2) Act 1975.
The Finance Bill 1976 sought to make a general revision of the taxation of benefits in kind. The existing legislation on fringe benefits was to be repealed. Clause 52 of the Bill as introduced eventually became section 61 of the Act of 1976 and imposed a charge to tax on benefits in kind for higher paid employees, i.e., those paid more than £5,000 per annum. Clause 54 of the Bill eventually became section 63 of the Act of 1976. As introduced, clause 54(1) provided that the cash equivalent of any benefit was to be an amount equal to “the cost of the benefit.” Clause 54(2) provided that, except as provided in later subsections “the cost of a benefit is the amount of any expense incurred in or in connection with its provision.” Crucially, clause 54(4) of the Bill sought to tax in-house benefits on a different basis from that applicable to external benefits. It provided that the cost of a benefit consisting of the provision of any service or facility which was also provided to the public (i.e., in-house benefits) should be the price which the public paid for such facility or service. Employees of schools were not excluded from the new charge.
Thus if the 1976 Bill had gone through as introduced, railway and airline employees would have been treated as receiving benefits in kind from concessionary travel equal to the open market cost of tickets and schoolmasters would have been taxed for concessionary education on the amount of the normal school fees.
After second reading, clause 52 of the Bill was committed to a committee of the whole House and clause 54 to Standing Committee E. On 17 May 1976, the House considered clause 52 and strong representations were made about the impact of clause 52 on airline and railway employees. At the start of the meeting of Standing Committee E on 17 June 1976 (before clause 54 was being discussed) the Financial Secretary to the Treasury, Mr. Robert Sheldon, made an announcement (Hansard, columns 893–895) in the following terms:
“The next point I wish to make concerns services and deals with the position of employees of organisations, bodies, or firms which provide services, where the employee is in receipt of those services free or at a reduced rate. Under clause 54(4) the taxable benefit is to be based on the arm's length price of the benefit received. At present the benefit is valued on the cost to the employer. Representations have been made concerning airline travel and railway employees …. It was never intended that the benefit received by the airline employee would be the fare paid by the ordinary passenger. The benefit to him would never be as high as that, because of certain disadvantages that the employee has. Similar considerations, although of a different kind, apply to railway employees. I have had many interviews, discussions and meetings on this matter and I have decided to withdraw clause 54(4). I thought I would mention this at the outset because so many details, which would normally be left until we reach that particular stage, will be discussed with earlier parts of the legislation. I shall give some reasons which weigh heavily in favour of the withdrawal of this provision. The first is the large difference between the cost of providing some services and the amount of benefit which under the Bill would be held to be received. There are a number of cases of this kind, and I would point out that air and rail journeys are only two of a number of service benefits which have a number of problems attached to them. But there is a large difference between the cost of the benefit to the employer and the value of that benefit as assessed. It could lead to unjustifiable situations resulting in a great number of injustices and I do not think we should continue with it ….
The second reason for withdrawing clause 54(4) is that these services would tend to be much less used. The problem would then arise for those who had advocated the continuation of this legislation that neither the employer nor the employee nor the Revenue would benefit from the lesser use of these services. This factor also weighed with me. The third reason is the difficulty of enforcement and administration, which both give rise to certain problems. Finally, it was possible to withdraw this part of the legislation as the services cover not only a more difficult area, but a quite distinct area of these provisions, without having repercussions on some of the other areas ….
A member: I, too, have talked to many airline employees about this matter, and I am not completely clear as to the purport of my Hon. Friend's remarks. Is he saying that these benefits will remain taxable but that the equivalent cost of the benefit will be calculated on some different basis? Or is he saying that these benefits will not be taxable at all?
Financial Secretary: The existing law which applies to the taxation of some of these benefits will be retained. The position will subsequently be unchanged from what it is now before the introduction of this legislation.”
The Financial Secretary was then asked to elucidate the impact of this on airline employees. At column 930, he is reported as saying:
“There is a difference between the provision of services to an employee earning less than £5,000 and an employee earning more than £5,000, or one who is a director. The position is quite clear. What we are withdrawing is the arm's-length valuation of benefit under clause 54(4) where an employer is providing services to the employee at a cost which may be very little. The employee earning more than £5,000 or the director will be assessed on the benefit received by him on the basis of the cost to the employer rather than the price that would generally be charged to the public. That is the position that we have now brought in, as opposed to the original one in the Bill where it would be assessed on the cost to a member of the public. That position now is the same as it stands before this legislation is passed.”
After being further pressed, the Financial Secretary said, at column 931:
“The position is as I have enunciated it. If a company provides a service to the kind of employee which we have been talking about, and the company subsidises that service, the benefit assessable on the employee is the cost to the employer of providing that service. This was to have been changed by clause 54(4) under which the benefit received was to be assessed at the arm's length price which an ordinary member of the public would have paid for that service. Some companies provide services of a kind where the cost to them is very little. For example, an airline ticket, allowing occupation of an empty seat, costs an airline nothing — in fact, in such a case there could be a negative cost, as it might be an advantage to the airline to have an experienced crew member on the flight. The cost to the company, then, would be nothing, but the benefit assessable under clause 54(4) could be considerable. We are reverting to the existing practice.”
He further said:
“If the company provides services to such people at a subsidised rate, the employee will be assessed on the benefit received on the basis of the cost to the employer. That is the position as it was before this Bill and as it will be if the whole of the Bill is passed, because subsection (2) only restates the existing position. It does not produce anything new (column 931).”
Simultaneously with the announcement to the Standing Committee, a press release was issued announcing the withdrawal of clause 54(4). It referred to the same matters as the Financial Secretary had stated to the Committee and concluded:
“The effect of deleting this subclause will be to continue the present basis of taxation of services, namely the cost to the employer of providing the service.”
The point was further debated in committee on 22 June 1976.
A member is reported as saying, at column 1013, that
“Like many others, I welcome the concession that has been made to leave out the airline staff and the railway employees and all the others that are left out by the dropping of clause 54(4).”
Another member, after referring to the particular reference in the Financial Secretary's statement to airline and railway employees, asked whether the same distinction applied to services provided by hotel companies to their employees — that is, to rooms which are freely available for the general public in hotels being offered at a concessionary rate to employees of the hotel group. In response, the Financial Secretary said of the position of such employees:
“The position is, as he probably expected, the same as that which, following my announcement last week about the withdrawal of clause 54(4), applies to other employees in service industries; the benefit is the cost to the employer. It is a good illustration of one of the reasons why I withdrew this subsection, in that the cost to the employer in this instance could be much less than the arm's-length cost to the outside person taking advantage of such a service.“(Column 1024.)
The question of the taxation of merchant seamen in respect of travel concessions to their families on their employers' ships was raised by another speaker and an amendment (No. 299) was tabled to meet their position. The Financial Secretary said, at column 1100:
“Perhaps I may discuss a closely allied problem under Amendment No. 299, to which a number of Hon. Gentlemen spoke. This proposal concerns the employee of a company and his wife, or the spouse, and the concession of a free passage or voyage in a company ship ‘once in each calendar year’ according to the amendment. I think that I can satisfy the Hon. Gentlemen that these voyages will not now be subject to tax as a result of the withdrawal of subsection (4), apart from the nominal charge for food which is normally made and which would be assessable. The current position more than meets the amendment. As I understand the matter, there could be a fair number of such voyages, and the only basis for charge would be on the cost to the employer, and in the example that we are considering that would be very small.”
The very question which is the subject matter of the present appeal was also raised. A member said, at columns 1091–1092:
“I should be grateful for the Financial Secretary's guidance on these two points …. The second matter applies particularly to private sector, fee-paying schools where, as the Financial Secretary knows, there is often an arrangement for the children of staff in these schools to be taught at less than the commercial fee in other schools. I take it that because of the deletion of clause 54(4) that is not now caught. Perhaps these examples will help to clarify the extent to which the Government amendment goes.”
The Financial Secretary responded to this question as follows:
“He mentioned the children of teachers. The removal of clause 54(4) will affect the position of a child of one of the teachers at the child's school, because now the benefit will be assessed on the cost to the employer, which would be very small indeed in this case.“(Column 1098.)
Thereafter, clause 54 was not the subject of further debate and passed into law as it now stands as section 63 of the Act.
The position can therefore be summarised as follows. The Bill as introduced sought by clause 54(4) to tax in-house benefits on a different basis from other benefits, i.e., not on the cost of the in-house benefit to the employer but on the open market price charged to the public. On the deletion of clause 54(4), in-house benefits were to be taxed on the same basis as external benefits, i.e., on the cost to the employer of providing the benefit. Numerous inquiries were made of the Financial Secretary to elucidate the resulting effect of the Bill on in-house benefits, i.e., concessionary travel for airline, railway and merchant navy employees, on benefits for hotel employees and on concessionary education for the children of teachers. In responding to each of these requests for information (save that relating to teachers), the Financial Secretary stated that the effect of the Bill would be to leave their position unchanged from the previous law. He explained that in each case (including that of teachers) the charge would be on the cost to the employer of providing the services and that in each case that cost would either be nil or very small. After these statements were made by the Financial Secretary the Bill passed into law without further discussion on this aspect of the matter.
Against that background I turn to consider the various issues which I have identified.
1. Should the rule prohibiting references to Parliamentary material be relaxed?
Under present law, there is a general rule that references to Parliamentary material as an aid to statutory construction is not permissible (“the exclusionary rule”): Davis v. Johnson  AC 264
and Hadmor Productions Ltd v. Hamilton  1 A.C. 191. This rule did not always apply but was judge made. Thus, in Ash v. Abdy (1678) 3 Swans. 664 Lord Nottingham took judicial notice of his own experience when introducing the Bill in the House of Lords. The exclusionary rule was probably first stated by Willes J. in Millar v. Taylor (1769) 4 Burr. 2303, 2332. However, the case of In re Mew and Thorne (1862) 31 L.J.Bank. 87 shows that even in the middle of the last century the rule was not absolute: in that case Lord Westbury L.C. in construing an Act had regard to its Parliamentary history and drew an inference as to Parliament's intention in passing the legislation from the making of an amendment striking out certain words.
The exclusionary rule was later extended so as to prohibit the court from looking even at reports made by commissioners on which legislation was based: Salkeld v. Johnson (1848) 2 Exch. 256, 273. This rule has now been relaxed so as to permit reports of commissioners, including law commissioners, and white papers to be looked at for the purpose solely of ascertaining the mischief which the statute is intended to cure but not for the purpose of discovering the meaning of the words used by Parliament to effect such cure: Eastman Photographic Materials Co. Ltd. v. Comptroller-General of Patents, Designs and Trademarks  A.C. 571 and Assam Railways and Trading Co. Ltd. v. Commissioners of Inland Revenue  AC 445
, 457–458. Indeed, in Reg. v. Secretary of State for Transport, Ex parte Factortame Ltd.  2 AC 85
your Lordships' House went further than this and had regard to a Law Commission report not only for the purpose of ascertaining the mischief but also for the purpose of drawing an inference as to Parliamentary intention from the fact that Parliament had not expressly implemented one of the Law Commission's recommendations.
Although the courts' attitude to reports leading to legislation has varied, until recently there was no modern case in which the court had looked at parliamentary debates as an aid to construction. However, in Pickstone v. Freemans Plc.  AC 66
this House, in construing a statutory instrument, did have regard to what was said by the Minister who initiated the debate on the regulations. My noble and learned friend, Lord Keith of Kinkel, at p. 112b, after pointing out that the draft Regulations were not capable of being amended when presented to Parliament, said that it was “entirely legitimate for the purpose of ascertaining the intention of Parliament to take into account the terms in which the draft was presented by the responsible Minister and which formed the basis of its acceptance.” My noble and learned friend, Lord Templeman, at pp. 121–122, also referred to the Minister's speech, although possibly only by way of support for a conclusion he had reached on other grounds. My noble and learned friends, Lord Brandon of Oakbrook and Lord Jauncey of Tullichettle, agreed with both those speeches. This case therefore represents a major inroad on the exclusionary rule: see also Owens Bank Ltd. v. Bracco  2 A.C. 443.
Mr. Lester, for the taxpayers, did not urge us to abandon the exclusionary rule completely. His submission was that where the words of a statute were ambiguous or obscure or were capable of giving rise to an absurd conclusion it should be legitimate to look at the Parliamentary history, including the debates in Parliament, for the purpose of identifying the intention of Parliament in using the words it did use. He accepted that the function of the court was to construe the actual words enacted by Parliament so that in no circumstances could the court attach to words a meaning that they were incapable of bearing. He further accepted that the court should only attach importance to clear statements showing the intention of the promoter of the Bill, whether a Minister or private member: there could be no dredging through conflicting statements of intention with a view to discovering the true intention of Parliament in using the statutory words.
In Beswick v. Beswick  AC 58
, 74 Lord Reid said:
“For purely practical reasons we do not permit debates in either House to be cited: it would add greatly to the time and expense involved in preparing cases involving the construction of a statute if counsel were expected to read all the debates in Hansard, and it would often be impracticable for counsel to get access to at least the older reports of debates in Select Committees of the House of Commons; moreover, in a very large proportion of cases such a search, even if practicable, would throw no light on the question before the court.”
In Black-Clawson International Ltd. v. Papierwerke Waldhof-Aschaffenburg A.G.  AC 591
Lord Reid said, at pp. 613–615:
“We often say that we are looking for the intention of Parliament, but that is not quite accurate. We are seeking the meaning of the words which Parliament used. We are seeking not what Parliament meant but the true meaning of what they said …. I have more than once drawn attention to the practicial difficulties … but the difficulty goes deeper. The questions which give rise to debate are rarely those which later have to be decided by the courts. One might take the views of the promoters of a Bill as an indication of the intention of Parliament but any view the promoters may have about the questions which later come before the court will not often appear in Hansard and often those questions have never occurred to the promoters. At best we might get material from which a more or less dubious inference might be drawn as to what the promoters intended or would have intended if they had thought about the matter, and it would, I think, generally be dangerous to attach weight to what some other members of either House may have said …. in my view, our best course is to adhere to present practice.”
In the same case Lord Wilberforce said, at p. 629:
“The second [reason] is one of constitutional principle. Legislation in England is passed by Parliament, and put in the form of written words. This legislation is given legal effect upon subjects by virtue of judicial decision, and it is the function of the courts to say what the application of the words used to particular cases or individuals is to be …. it would be a degradation of that process if the courts were to be merely a reflecting mirror of what some other interpretation agency might say.”
In Fothergill v. Monarch Airlines Ltd.  AC 251
, 279, Lord Diplock said:
“The constitutional function performed by courts of justice as interpreters of the written law laid down in Acts of Parliament is often described as ascertaining ‘the intention of Parliament;’ but what this metaphor, though convenient, omits to take into account is that the court, when acting in its interpretative role, as well as when it is engaged in reviewing the legality of administrative action, is doing so as mediator between the state in the exercise of its legislative power and the private citizen for whom the law made by Parliament constitutes a rule binding upon him and enforceable by the executive power of the state. Elementary justice or … the need for legal certainty demands that the rules by which the citizen is to be bound should be ascertainable by him (or, more realistically, by a competent lawyer advising him) by reference to identifiable sources that are publicly accessible.”
In Davis v. Johnson  AC 264
, 350, Lord Scarman said:
“such material is an unreliable guide to the meaning of what is enacted. It promotes confusion, not clarity. The cut and thrust of debate and the pressures of executive responsibility, the essential features of open and responsible government, are not always conducive to a clear and unbiased explanation of the meaning of statutory language. And the volume of Parliamentary and ministerial utterances can confuse by its very size.”
Thus the reasons put forward for the present rule are first, that it preserves the constitutional proprieties leaving Parliament to legislate in words and the courts (not Parliamentary speakers), to construe the meaning of the words finally enacted; second, the practical difficulty of the expense of researching Parliamentary material which would arise if the material could be looked at; third, the need for the citizen to have access to a known defined text which regulates his legal rights; fourth, the improbability of finding helpful guidance from Hansard.
The Law Commissions of England and Scotland in their joint Report on the Interpretation of Statutes in 1969 and the Renton Committee on the Preparation of Legislation both recognised that there was much to be said in principle for relaxing the rule but advised against a relaxation at present on the same practical grounds as are reflected in the authorities. However, both bodies recommended changes in the form of legislation which would, if implemented, have assisted the court in its search for the true Parliamentary intention in using the statutory words.
Mr. Lester submitted that the time has come to relax the rule to the extent which I have mentioned. He points out that the courts have departed from the old literal approach of statutory construction and now adopt a purposive approach, seeking to discover the Parliamentary intention lying behind the words used and construing the legislation so as to give effect to, rather than thwart, the intentions of Parliament. Where the words used by Parliament are obscure or ambiguous, the Parliamentary material may throw considerable light not only on the mischief which the Act was designed to remedy but also on the purpose of the legislation and its anticipated effect. If there are statements by the Minister or other promoter of the Bill, these may throw as much light on the “mischief” which the Bill seeks to remedy as do the white papers, reports of official committees and Law Commission reports to which the courts already have regard for that purpose. If a Minister clearly states the effect of a provision and there is no subsequent relevant amendment to the Bill or withdrawal of the statement it is reasonable to assume that Parliament passed the Bill on the basis that the provision would have the effect stated. There is no logical distinction between the use of ministerial statements introducing subordinate legislation (to which recourse was had in the Pickstone case  AC 66
) and such statements made in relation to other statutory provisions which are not in fact subsequently amended. Other common law jurisdictions have abandoned the rule without adverse consequences. Although the practical reasons for the rule (difficulty in getting access to Parliamentary materials and the cost and delay in researching it) are not without substance, they can be greatly exaggerated: experience in Commonwealth countries which have abandoned the rule does not suggest that the drawbacks are substantial, provided that the court keeps a tight control on the circumstances in which references to Parliamentary material are allowed.
On the other side, the Attorney-General submitted that the existing rule had a sound constitutional and practical basis. If statements by Ministers as to the intent or effect of an Act were allowed to prevail, this would contravene the constitutional rule that Parliament is “sovereign only in respect of what it expresses by the words used in the legislation it has passed:” per
Lord Diplock in Black-Clawson  AC 591
, 638e. It is for the courts alone to construe such legislation. It may be unwise to attach importance to ministerial explanations which are made to satisfy the political requirements of persuasion and debate, often under pressure of time and business. Moreover, in order to establish the significance to be attached to any particular statement, it is necessary both to consider and to understand the context in which it was made. For the courts to have regard to Parliamentary material might necessitate changes in Parliamentary procedures to ensure that ministerial statements are sufficiently detailed to be taken into account. In addition, there are all the practical difficulties as to the accessibility of Parliamentary material, the cost of researching it and the use of court time in analysing it, which are good reasons for maintaing the rule. Finally, to use what is said in Parliament for the purpose of construing legislation would be a breach of article 9 of the Bill of Rights as being an impeachment or questioning of the freedom of speech in debates in proceedings in Parliament.
My Lords, I have come to the conclusion that, as a matter of law, there are sound reasons for making a limited modification to the existing rule (subject to strict safeguards) unless there are constitutional or practical reasons which outweigh them. In my judgment, subject to the questions of the privileges of the House of Commons, reference to Parliamentary material should be permitted as an aid to the construction of legislation which is ambiguous or obscure or the literal meaning of which leads to an absurdity. Even in such cases references in court to Parliamentary material should only be permitted where such material clearly discloses the mischief aimed at or the legislative intention lying behind the ambiguous or obscure words. In the case of statements made in Parliament, as at present advised I cannot foresee that any statement other than the statement of the Minister or other promoter of the Bill is likely to meet these criteria.
I accept Mr. Lester's submissions, but my main reason for reaching this conclusion is based on principle. Statute law consists of the words that Parliament has enacted. It is for the courts to construe those words and it is the court's duty in so doing to give effect to the intention of Parliament in using those words. It is an inescapable fact that, despite all the care taken in passing legislation, some statutory provisions when applied to the circumstances under consideration in any specific case are found to be ambiguous. One of the reasons for such ambiguity is that the members of the legislature in enacting the statutory provision may have been told what result those words are intended to achieve. Faced with a given set of words which are capable of conveying that meaning it is not surprising if the words are accepted as having that meaning. Parliament never intends to enact an ambiguity. Contrast with that the position of the courts. The courts are faced simply with a set of words which are in fact capable of bearing two meanings. The courts are ignorant of the underlying Parliamentary purpose. Unless something in other parts of the legislation discloses such purpose, the courts are forced to adopt one of the two possible meanings using highly technical rules of construction. In many, I suspect most, cases references to Parliamentary materials will not throw any light on the matter. But in a few cases it may emerge that the very question was considered by Parliament in passing the legislation. Why in such a case should the courts blind themselves to a clear indication of what Parliament intended in using those words? The court cannot attach a meaning to words which they cannot bear, but if the words are capable of bearing more than one meaning why should not Parliament's true intention be enforced rather than thwarted?
A number of other factors support this view. As I have said, the courts can now look at white papers and official reports for the purpose of finding the “mischief” sought to be corrected, although not at draft clauses or proposals for the remedying of such mischief. A ministerial statement made in Parliament is an equally authoritative source of such information: why should the courts be cut off from this source of information as to the mischief aimed at? In any event, the distinction between looking at reports to identify the mischief aimed at but not to find the intention of Parliament in enacting the legislation is highly artificial. Take the normal Law Commission Report which analyses the problem and then annexes a draft Bill to remedy it. It is now permissible to look at the report to find the mischief and at the draft Bill to see that a provision in the draft was not
included in the legislation enacted: see the Factortame case  2 AC 85
. There can be no logical distinction between that case and looking at the draft Bill to see that the statute as enacted reproduced, often in the same words, the provision in the Law Commissions's draft. Given the purposive approach to construction now adopted by the courts in order to give effect to the true intentions of the legislature, the fine distinctions between looking for the mischief and looking for the intention in using words to provide the remedy are technical and inappropriate. Clear and unambiguous statements made by Ministers in Parliament are as much the background to the enactment of legislation as white papers and Parliamentary reports.
The decision in Pickstone v. Freemans Plc.  AC 66
which authorises the court to look at ministerial statements made in introducing regulations which could not be amended by Parliament is logically indistinguishable from such statements made in introducing a statutory provision which, though capable of amendment, was not in fact amended.
The judicial antipathy to relaxing the rule has been far from uniform. Lord Reid, who in the passage I have quoted from the Black-Clawson case  AC 591
, 613–615, supported the maintenance of the rule, in his dissenting speech in Reg. v. Warner  2 A.C. 256, 279 said:
“the layman may well wonder why we do not consult the Parliamentary Debates, for we are much more likely to find the intention of Parliament there than anywhere else. The rule is firmly established that we may not look at Hansard and in general I agree with it, for reasons which I gave last year in Beswick v. Beswick. This is not a suitable case in which to reopen the matter but I am bound to say that this case seems to show that there is room for an exception where examining the proceedings in Parliament would almost certainly settle the matter immediately one way or the other.”
Lord Wilberforce (whose words I have also quoted) had second thoughts in an extra-judicial capacity at a seminar in Canberra ( Symposium on Statutory Interpretation, Canberra, 1983, p. 13) where he referred to a case in which the Minister on two occasions during the passage of a Finance Bill stated expressly that the provision was not intended to tax a particular class of beneficiary. Yet subsequently beneficiaries of that class were sought to be taxed under the statutory provision. Lord Wilberforce suggested that there should be a relaxation of the exclusionary rule so that where a Minister promoting a Bill makes an explicit and official statement as to the meaning or scope of the provision, reference should be allowed to that statement.
Text books often include reference to explanations of legislation given by a Minister in Parliament, as a result of which lawyers advise their clients taking account of such statements and judges when construing the legislation come to know of them. In addition, a number of distinguished judges have admitted to breaching the exclusionary rule and looking at Hansard in order to seek the intention of Parliament. When this happens, the parties do not know and have no opportunity to address the judge on the matter. A vivid example of this occurred in the Hadmor case  1 A.C. 191 where Lord Denning M.R. in the Court of Appeal relied on his own researches into Hansard in reaching his conclusions: in the House of Lords, counsel protested that there were other passages to which he would have wished to draw the court's attention had he known that Lord Denning M.R. was looking at Hansard: see the Hadmor case at p. 233. It cannot be right for such information to be available, by a sidewind, for the court but the parties be prevented from presenting their arguments on such material.
Against these considerations, there have to be weighed the practical and constitutional matters urged by the Attorney-General many of which have been relied on in the past in the courts in upholding the exclusionary rule. I will first consider the practical difficulties.
It is said that Parliamentary materials are not readily available to, and understandable by, the citizen and his lawyers who should be entitled to rely on the words of Parliament alone to discover his position. It is undoubtedly true that Hansard and particularly records of Committee debates are not widely held by libraries outside London and that the lack of satisfactory indexing of Committee stages makes it difficult to trace the passage of a clause after it is redrafted or renumbered. But such practical difficulties can easily be overstated. It is possible to obtain Parliamentary materials and it is possible to trace the history. The problem is one of expense and effort in doing so, not the availability of the material. In considering the right of the individual to know the law by simply looking at legislation, it is a fallacy to start from the position that all legislation is available in a readily understandable form in any event: the very large number of statutory instruments made every year are not available in an indexed form for well over a year after they have been passed. Yet, the practitioner manages to deal with the problem albeit at considerable expense. Moreover, experience in New Zealand and Australia (where the strict rule has been relaxed for some years) has not shown that the non-availability of materials has raised these practical problems.
Next, it is said that lawyers and judges are not familiar with Parliamentary procedures and will therefore have difficulty in giving proper weight to the Parliamentary materials. Although, of course, lawyers do not have the same experience of these matters as members of the legislature, they are not wholly ignorant of them. If, as I think, significance should only be attached to the clear statements made by a Minister or other promoter of the Bill, the difficulty of knowing what weight to attach to such statements is not overwhelming. In the present case, there were numerous statements of view by members in the course of the debate which plainly do not throw any light on the true construction of section 63. What is persuasive in this case is a consistent series of answers given by the Minister, after opportunities for taking advice from his officials, all of which point the same way and which were not withdrawn or varied prior to the enactment of the Bill.
Then it is said that court time will be taken up by considering a mass of Parliamentary material and long arguments about its significance, thereby increasing the expense of litigation. In my judgment, though the introduction of further admissible material will inevitably involve some increase in the use of time, this will not be significant as long as courts insist that Parliamentary material should only be introduced in the limited cases I have mentioned and where such material contains a clear indication from the Minister of the mischief aimed at, or the nature of the cure intended, by the legislation. Attempts to introduce material which does not satisfy those tests should be met by orders for costs made against those who have improperly introduced the material. Experience in the United States of America, where legislative history has for many years been much more generally admissible than I am now suggesting, shows how important it is to maintain strict control over the use of such material. That position is to be contrasted with what has happened in New Zealand and Australia (which have relaxed the rule to approximately the extent that I favour): there is no evidence of any complaints of this nature coming from those countries.
There is one further practical objection which, in my view, has real substance. If the rule is relaxed legal advisers faced with an ambiguous statutory provision may feel that they have to research the materials to see whether they yield the crock of gold, i.e., a clear indication of Parliament's intentions. In very many cases the crock of gold will not be discovered and the expenditure on the research wasted. This is a real objection to changing the rule. However again it is easy to overestimate the cost of such research: if a reading of Hansard shows that there is nothing of significance said by the Minister in relation to the clause in question, further research will become pointless.
In sum, I do not think that the practical difficulties arising from a limited relaxation of the rule are sufficient to outweigh the basic need for the courts to give effect to the words enacted by Parliament in the sense that they were intended by Parliament to bear. Courts are frequently criticised for their failure to do that. This failure is due not to cussedness but to ignorance of what Parliament intended by the obscure words of the legislation. The courts should not deny themselves the light which Parliamentary materials may shed on the meaning of the words Parliament has used and thereby risk subjecting the individual to a law which Parliament never intended to enact.
Is there, then, any constitutional objection to a relaxation of the rule? The main constitutional ground urged by the Attorney-General is that the use of such material will infringe article 9 of the Bill of Rights as being a questioning in any court of freedom of speech and debates in Parliament. As I understood the submission, the Attorney-General was not contending that the use of Parliamentary material by the courts for the purposes of construction would constitute an “impeachment” of freedom of speech since impeachment is limited to cases where a Member of Parliament is sought to be made liable, either in criminal or civil proceeding, for what he has said in Parliament, e.g., by criminal prosecution, by action for libel or by seeking to prove malice on the basis of such words. The submission was that the use of Hansard for the purpose of construing an Act would constitute a “questioning” of the freedom of speech or debate. The process, it is said, would involve an investigation of what the Minister meant by the words he used and would inhibit the Minister in what he says by attaching legislative effect to his words. This, it was submitted, constituted “questioning” the freedom of speech or debate.
Article 9 is a provision of the highest constitutional importance and should not be narrowly construed. It ensures the ability of democratically elected Members of Parliament to discuss what they will (freedom of debate) and to say what they will (freedom of speech). But even given a generous approach to this construction, I find it impossible to attach the breadth of meaning to the word “question” which the Attorney-General urges. It must be remembered that article 9 prohibits questioning not only “in any court” but also in any “place out of Parliament.” If the Attorney-General's submission is correct, any comment in the media or elsewhere on what is said in Parliament would constitute “questioning” since all Members of Parliament must speak and act taking into account what political commentators and other will say. Plainly article 9 cannot have effect so as to stifle the freedom of all to comment on what is said in Parliament, even though such comment may influence Members in what they say.
In my judgment, the plain meaning of article 9, viewed against the historical background in which it was enacted, was to ensure that Members of Parliament were not subjected to any penalty, civil or criminal for what they said and were able, contrary to the previous assertions of the Stuart monarchy, to discuss what they, as opposed to the monarch, chose to have discussed. Relaxation of the rule will not involve the courts in criticising what is said in Parliament. The purpose of looking at Hansard will not be to construe the words used by the Minister but to give effect to the words used so long as they are clear. Far from questioning the independence of Parliament and its debates, the courts would be giving effect to what is said and done there.
Moreover, the Attorney-General's contentions are inconsistent with the practice which has now continued over a number of years in cases of judicial review. In such cases, Hansard has frequently been referred to with a view to ascertaining whether a statutory power has been improperly exercised for an alien purpose or in a wholly unreasonable manner. In Reg. v. Secretary of State for the Home Department, Ex parte Brind  1 AC 696
it was the Crown, at p. 741F, which invited the court to look at Hansard to show that the Minister in that case had acted correctly. This House attached importance to what the Minister had said: see pp. 749D and 755B. The Attorney-General accepted that references to Hansard for the purposes of judicial review litigation did not infringe article 9. Yet reference for the purposes of judicial review and for the purposes of construction are indistinguishable. In both types of case, the Minister's words are considered and taken into account by the court: in both, the use of such words by the courts might affect what is said in Parliament.
As to the authorities, in Church of Scientology of California v. Johnson-Smith  1 Q.B. 522, the plaintiff sued the defendant, a Member of Parliament, for an alleged libel on television and sought to introduce evidence of what the defendant had said in the House of Commons as proof of malice. Browne J. held, rightly in my view, that such use would breach article 9 as questioning the motives and intentions of a Member of the House. To the extent that he went further so as to suggest that in no circumstances could the speeches be looked at other than for the purposes of seeing what was said on a particular date, his remarks have to be understood in the context of the issues which arose in that case. Those issues included an allegation that the defendant acted improperly in Parliament in saying what he did in Parliament. That plainly would amount to questioning a member's behaviour in Parliament and infringe article 9.
In Reg. v. Secretary of State for Trade, Ex parte Anderson Strathclyde Plc.  2 All E.R. 233 an applicant for judicial review sought to adduce Parliamentary materials to prove a fact. The Crown did not object to the Divisional Court looking at the materials (see p. 237G–H) but the court itself refused to do so on the grounds that it would constitute a breach of article 9. In view of the Attorney-General's concession and the decision of this House in Ex parte Brind, in my judgment Reg. v. Secretary of State for Trade, Ex parte Anderson Strathclyde Plc.  2 All E.R. 233 was wrongly decided on this point.
Accordingly in my judgment the use of clear ministerial statements by the court as a guide to the construction of ambiguous legislation would not contravene article 9. No doubt all judges will be astute to ensure that counsel does not in any way impugn or criticise the Minister's statements or his reasoning.
The Attorney-General raised a further constitutional point, namely, that for the court to use Parliamentary material in construing legislation would be to confuse the respective roles of Parliament as the maker of law and the courts as the interpreter. I am not impressed by this argument. The law, as I have said, is to be found in the words in which Parliament has enacted. It is for the courts to interpret those words so as to give effect to that purpose. The question is whether, in addition to other aids to the construction of statutory words, the courts should have regard to a further source. Recourse is already had to white papers and official reports not because they determine the meaning of the statutory words but because they assist the court to make its own determination. I can see no constitutional impropriety in this.
Finally on this aspect of the case, the Attorney-General relied on considerations of comity: the relaxation of the rule would have a direct effect on the rights and privileges of Parliament. To the extent that such rights and privileges are to be found in the Bill of Rights, in my judgment they will not be infringed for the reasons which I have given. I deal below (at 5) with any other Parliamentary privileges there may be.
I therefore reach the conclusion, subject to any question of Parliamentary privilege, that the exclusionary rule should be relaxed so as to permit reference to Parliamentary materials where (a) legislation is ambiguous or obscure, or leads to an absurdity; (b) the material relied upon consists of one or more statements by a Minister or other promoter of the Bill together if necessary with such other Parliamentary material as is necessary to understand such statements and their effect; (c) the statements relied upon are clear.
Further than this, I would not at present go.
2. Does this case fall within the relaxed rule?
( a) Is section 63 ambiguous?
I have no hesitation in holding that it is. The “expense incurred in or in connection with” the provision of in-house benefits may be either the marginal cost caused by the provision of the benefit in question or a proportion of the total cost incurred in providing the service both for the public and for the employee (“the average cost”).
In favour of the marginal cost argument, it is submitted by the taxpayer that there has to be a causal link between the benefit in kind taxed under section 61(1) and its “cash equivalent:” section 63(1) defines the cash equivalent of the benefit as being an amount equal to the cost of the benefit. Therefore, it is said, one is looking for the actual cost of providing that benefit for the employee. The basic expense of providing and running the school would have been incurred in any event: therefore that expenditure is not caused by the provision of the benefit for the employee. The test is whether the cost would have been incurred but for the provision of the benefit. Therefore, when one comes to section 63(2) one is looking for the additional expense incurred in or in connection with the provision of the benefit.
The taxpayers' contention is supported by certain unfair consequences which could ensue if the cost of the benefit is to be taken as the average cost. Take a railway running at a loss: the average cost of providing concessionary travel would be a sum greater than the fare charged to the public. In the case of a heavily endowed school, the fees charged to the public may be less than sufficient to cover the total cost of running the school, the shortfall being made good by the endowment. On the average cost basis, the taxpayer would be treated as receiving a benefit greater than the amount charged to the public.
On the other side, the revenue contend that once one has identified the benefit under section 61, section 63 contains a code for establishing its cash equivalent. Section 63(1) defines the cash equivalent as the cost of the benefit and section 63(2) defines “the cost of a benefit” as being the expense “incurred in or in connection with” its provision. The benefit in this case consists of the enjoyment of the facilities of the school. What is the cost of providing those facilities? It must be the total cost of providing the school. However the total cost of providing the school is incurred not only in connection with the provision of the benefit to the employee but also in providing the school with fee paying boys. This provision is expressly covered by the final words of section 63(2) “and includes … a proper proportion of any expense relating partly to the benefit and partly to other matters.” Therefore, says the revenue, the cost of the benefit is a proportion of the total cost of providing the services. The revenue has no answer to the anomalies which arise when the cost of providing a loss-making facility means that the average cost basis results in the taxpayer being treated as receiving a sum by way of benefit greater than the cost of buying that benefit on the open market.
I find these arguments nicely balanced. The statutory words are capable of bearing either meaning. There is an ambiguity or obscurity.
( b) Are the words of the Financial Secretary clear?
It is necessary by way of preface to emphasise that in no circumstances can in-house benefits give rise to no taxable benefit or only a small taxable benefit if that benefit is to be assessed on an average cost basis. The average cost basis means that the cost will approximate to the open market charge (less any profit element) and therefore must in all circumstances be substantial.
The 1976 Finance Bill as introduced proposed to charge in-house benefits on a different basis from that applicable to external benefits, i.e., on the open market price charged to the public: clause 54(4). Once the Government announced its intention to withdraw clause 54(4) a number of Members were anxious to elucidate what effect this would have on classes of taxpayers who enjoyed in-house benefits: concessionary transport for railwaymen, airline employees and merchant seamen; concessionary accommodation for hotel employees; concessionary education for the children of teachers. In answer to these inquiries the Financial Secretary gave similar answers in relation to each class namely (1) that in all the cases (except that of the teachers' concessionary education) that the benefits would be taxed on the same basis as under the existing law and (2) that in all cases the amount of the charge would be nil, small or, in the case of the schoolteachers, “very small indeed.” In my view these repeated assurances are quite inconsistent with the Minister having had, or communicated, any intention other than that the words “the expense incurred in or in connection with” the provision of the benefit would produce a charge to tax on the additional or marginal cost only, not a charge on the average cost of the benefit.
It may be said that the Financial Secretary's reference to the taxpayers being liable to tax as under the pre-existing law (i.e., under the Finance Act 1948, section 39 as re-enacted by the Income and Corporation Taxes Act 1970) shows that he was saying that the position was unchanged: nothing the Minister said could effect the proper construction of legislation already on the statute book. To this contention there are, in my judgment two answers. First the old Acts were repealed by the Act of 1976: the provisions were re-enacted in different language, albeit that the phrase “incurred in or in connection with the provision of the benefit” appeared in both statutes. In this case the court is concerned to construe the Act of 1976: what is relevant is the ministerial statement as to the effect of that Act. Second, the existing practice of the revenue under the pre-1976 law was not to tax benefits in kind on the average cost basis and those who were asking questions on behalf of their constituents would have been well aware of this fact. For example in the case of the airline employees the revenue had sought to tax concessionary travel on the average cost basis but their claim had failed before the commissioners and they had not persisted in that claim. The Minister's answer in Parliament that the cost to the airlines of providing concessionary travel for airline employees would be nothing was exactly what in practice had been happening under the old law.
The question then arises whether it is right to attribute to Parliament as a whole the same intention as that repeatedly voiced by the Financial Secretary. In my judgment it is. It is clear from reading Hansard that the Committee was repeatedly asking for guidance as to the effect of the legislation once subclause (4) of clause 54 was abandoned. That Parliament relied on the ministerial statements is shown by the fact that the matter was never raised again after the discussions in Committee, that amendments were consequentially withdrawn and that no relevant amendment was made which could affect the correctness of the Minister's statement.
Accordingly, in my judgment we have in this case a clear statement by the responsible Minister stating the effect of the ambiguous words used in what became section 63 of the Act of 1976 which the Parliamentary history shows to have been the basis on which that section was enacted.
3. If reference to Hansard is permissible, what is the true construction of clause 63?
In my judgment there can be no doubt that, if Parliamentary privilege does not prohibit references to Hansard, the Parliamentary history shows that Parliament passed the legislation on the basis that the effect of sections 61 and 63 of the Act was to assess in-house benefits, and particularly concessionary education for teachers' children, on the marginal cost to the employer and not on the average cost. Since the words of section 63 are perfectly capable of bearing that meaning, in my judgment that is the meaning they should be given.
I have had the advantage of reading in draft the speech of my noble and learned friend on the Woolsack. In construing the Act without reference to the Parliamentary proceedings, he treats it as decisive that in this case the taxpayers' children were only occupying surplus accommodation and that it lay in the discretion of the school whether to grant such benefit to the taxpayers. This approach draws a distinction which is not reflected in the Parliamentary proceedings. Concessionary travel for railwaymen is not discretionary nor is it dependent on there being surplus seats on any train. Similarly, in many cases the education of teachers' children at concessionary rates is neither discretionary nor dependent on there being surplus capacity. Yet in both cases in Parliament the section was put forward as providing that only the marginal cost would be treated as taxable. I can therefore find no ground for drawing the narrow distinction and would hold that in the case of all in-house benefits the same test applies, viz. the cost of the benefit to the employer is the additional or marginal cost only.
Therefore if reference to Hansard is permissible, I would allow the appeal.
4. If reference to Hansard is not permissible, what is the true construction?
Having once looked at what was said in Parliament, it is difficult to put it out of mind. I have the advantage that, after the first hearing and before seeing the Parliamentary materials, I had reached the conclusion, in agreement with Vinelott J. and the Court of Appeal, that the revenue's submissions were correct. If it is not permissible to take into account what was said by the Financial Secretary, I remain of the same view.
My reasons are the same as those given by the Court of Appeal. I accept Mr. Lester's submission that there must be a causal link between the benefit provided for the taxpayers and the cost of the benefit referred to in section 63(1). But in my judgment section 63(2) provides a statutory formula for quantifying such cost: it requires one to find “the amount of any expense incurred in or in connection with” the provision of the benefit, such expense to include “a proper proportion of any expense relating partly to the benefit and partly to other matters.”
To apply section 63(2) it is first necessary to identify “the benefit.” It has throughout been common ground that the benefit in this case to each taxpayer is that “his son is allowed to participate in all the facilities afforded by the school to boys who are educated there.” These facilities are exactly the same as those afforded to every boy in the school, whether his parents are paying the full or concessionary fees. Therefore the relevant question is “what is the expense incurred in or in connection with providing those facilities.” On the literal meaning of the words, the expense to the school of providing those facilities is exactly the same for each boy in the school, i.e., a proportion of the total cost of running the school.
Even if it could be said that, because the school would have incurred the basic expense of running the school in any event, such expense was not incurred “in” providing the facilities for the taxpayer's child, on the literal meaning of the words such expense was in any event incurred “in connection with” the provision of such facilities. The words “in connection with” have the widest connotation and I cannot see how they are to be restricted in the absence of some context permitting such restriction.
The strongest argument in favour of the taxpayers is the anomaly which would arise if the employer's business were running at a loss or was subsidised by endowment. As I have explained, in such a case the adoption of the literal meaning of the statutory words would lead to a result whereby the taxpayer is assessed at an amount greater than that charged by the employer to the public for the same service. The Crown have no answer to this anomaly as such. But there are other anomalies which arise if the taxpayer's argument is correct. For example if, unlike the present case, the school could have been filled with boys paying the full fee, the school would have lost the fee income from the places occupied by the children of the taxpayers for whom only the concessionary fee was payable. Without deciding the point, it seems to me arguable that, on the taxpayer's argument, such loss or part of it would be an expense incurred by the school in providing the concessionary places. If so, the amount on which the taxpayer would be assessed to tax would vary from year to year depending upon the success of the school in attracting applicants. To my mind such a variation on a year by year basis by reference to an extraneous factor would be a most anomalous result, and would involve great difficulties in quantifying the cost to the employer in each case.
In the circumstances, if I could detect from the statute any statutory purpose or intention pointing to one construction rather than the other, I would certainly adopt it. But the statute yields no hint. The basic problem is this. What is taxable is the benefit to the employee and one would have expected the quantum of that benefit to be assessed by reference to the value of the benefit to the employee. But the statutory formula does not seek to value the benefit to the employee as such, but requires the quantum of the benefit to be fixed by reference to the cost to the employer in providing it. Given this dislocation between the benefit which is assessable to tax and the basis on which its value is to be assessed it is impossible to gain any guidance in the statute as to the Parliamentary intention. In the circumstances there is in my judgment no option but to give effect to the literal meaning of the words as did the Court of Appeal. In the result, the revenue's argument should succeed and the appeal should be dismissed.
5. Parliamentary privilege
It follows from what I have said that in my view the outcome of this appeal depends upon whether or not the court can look at Parliamentary material. If it can, the appeal should be allowed. If it cannot, the appeal should be dismissed. For the reasons I have given, as a matter of pure law this House should look at Hansard and give effect to the Parliamentary intention it discloses in deciding the appeal. The problem is the indication given by the Attorney-General that if this House does so, your Lordships may be infringing the privileges of the House of Commons.
For the reasons I have given, in my judgment reference to Parliamentary materials for the purpose of construing legislation does not breach article 9 of the Bill of Rights. However, the Attorney-General courteously but firmly warned your Lordships that this did not conclude the question. He said that article 9 was an illustration of the right that the House of Commons had won by 1688 to exclusive cognisance of its own proceedings. He continued:
“I remain convinced … that the House of Commons would regard a decision by your Lordships to use Hansard to construe a statute as a grave step and that the House of Commons may well regret that its views were not sought on such an important matter before your Lordships reached a decision.”
My Lords, this House and the courts have always been, and I trust will always continue to be, zealous in protecting Parliamentary privileges. I have therefore tried to discover some way in which this House can fulfil its duty to decide the case before it without trespassing on the sensibilities of the House of Commons. But I can find no middle course. Although for a considerable time before the resumed hearing it was known that this House was to consider whether to permit Hansard to be used as an aid to construction, there was no suggestion from the Crown or anyone else that such a course might breach Parliamentary privilege until the Attorney-General raised the point at the start of the rehearing. Even then, the Attorney-General did not ask for an adjournment to enable the House of Commons to consider the matter. Your Lordships therefore heard the case through to the end of the argument.
Although in the past the courts and the House of Commons both claimed the exclusive right to determine whether or not a privilege existed, it is now apparently accepted that it is for the courts to decide whether a privilege exists and for the House to decide whether such privilege has been infringed: see Erskine May on Parliamentary Practice
, 21st ed. (1989), pp. 147–160. Thus, Erskine May
says, at p. 150:
“In the 19th century, a series of cases forced upon the Commons and courts a comprehensive review of the issues which divided them, from which it became clear that some of the earlier claims to jurisdiction made in the name of privilege by the House of Commons were untenable in a court of law: that the law of Parliament was part of the general law, that its principles were not beyond the judicial knowledge of the judges, and that it was the duty of the common law to define its limits could no longer be disputed.”
Again it is said, at p. 154:
“Though events have revealed no single doctrine by which all issues of privilege arising between Parliament and the courts may be resolved, many of the problems of earlier years which are dealt with above have been substantially solved. Neither House is by itself entitled to claim the supremacy over the courts of law enjoyed by the undivided medieval High Court of Parliament. Since neither House can by its own declaration create a new privilege, privilege may be considered to be capable of being ascertained and thus judicially known to the courts.”
Accordingly, if the nature of the privilege going beyond the Bill of Rights had been identified, your Lordships could have determined whether or not such privilege exists, although it would be for the House of Commons to determine whether or not there was an infringment of any privilege found to exist. In fact, neither the letter from the Clerk of the Commons nor the Attorney-General have identified or specified the nature of any privilege extending beyond that protected by the Bill of Rights. In the absence of a claim to a defined privilege as to the validity of which your Lordships could make a determination, it would not in my view be right to withhold from the taxpayers a decision to which, in law, they are entitled. I would therefore allow the appeal.
I trust when the House of Commons comes to consider the decision in this case, it will be appreciated that there is no desire to impeach its privileges in any way. Your Lordships are motivated by a desire to carry out the intentions of Parliament in enacting legislation and have no intention or desire to question the processes by which such legislation was enacted or of criticising anything said by anyone in Parliament in the course of enacting it. The purpose is to give effect to, not thwart, the intentions of Parliament.
