“ Whatever the difficulties the court has to do its best to make sense of the statute, and that means not only making grammatical sense of the text but also finding a rational scheme in the legislation. That is not to say that the court should start off with preconceptions about what it expects to find, or that it should shrink from saying so in the rare case where a tax statute has “plainly missed fire” (the expression used by Lord Macmillan in IRC v Ayrshire Employers Mutual Assurance Association (1946) 27 TC 331, 347). But as Viscount Simon LC said in Nokes v Doncaster Amalgamated Collieries[1940] AC 10 14, 1022 (which was not a tax case, but has often been cited in tax cases): “... if the choice is between two interpretations, the narrower of which would fail to achieve the manifest purpose of the legislation, we should avoid a construction which would reduce the legislation to futility and should rather accept the bolder construction based on the view that Parliament would legislate only for the purpose of bringing about an effective result.” ” 42. Having set the scene we must address the submissions of the parties. Mr Aaronson submitted that HMRC’s interpretation of section 171A gives the words a meaning that Parliament would never have intended or contemplated. He criticised HMRC’s construction as being hyper-literal and giving a result which makes no sense, excludes normal commercial transactions, such as the redemption of loan notes or shares, and serves no conceivable purpose. Mr Gibbon on the other hand disavowed any literal construction and maintained that HMRC was construing the provision purposively. 43. We were referred by both parties to a number of extra-statutory materials from which they sought to derive the intention of Parliament. These comprised the Budget Notes issued prior to the Finance Bill 2000, extracts from Hansard in relation to a Parliamentary Debate on the Finance Bill 2000 and the Explanatory Notes for Finance Bill 2000. Each referred to what was or was to become clause 100 of the Finance Bill 2000. 44. The short extract from Hansard to which we were taken does not address the issue we have to determine on this appeal. Even if it were admissible pursuant to Pepper v Hart[1993] AC 593 it provides no assistance in determining that issue. Nor in our view do the Budget Notes shed any light on the issue of construction. 45. We are entitled to take into account the Explanatory Note to clause 100 (see Westminster City Council v National Asylum Support Service[2002] UKHL 38 at [4] to [6] ). Neither party placed substantial reliance on the Notes, but both Mr Aaronson and Mr Gibbon referred to them and we set out in particular the background referred to in the Notes: “ 8. There is no group relief provision for capital losses by which a company can surrender capital losses to be set against the chargeable gains of another group member. A form of such relief is available by utilising the rules which allow tax neutral transfers of assets between group members. This is achieved by transferring an asset on a tax neutral basis before its eventual disposal outside the group , so that chargeable gains and allowable losses are brought together within a single company. 9. This has necessitated the actual transfer of ownership of an asset between group companies before the disposal outside the group. This new provision, which emerged from consultation with representative bodies, will allow the effect to be achieved by an election by two group members, without the need for the actual transfer of ownership of the asset. 10. The new provision will reduce compliance costs and make it simpler for groups to bring together gains and losses. Groups will be able to make sales of assets without the preliminary transfer between group companies, and will be able to make elections under the new provision up to two years after the accounting period in which the sale took place. ” (Emphasis added)
