“ … v) The fundamental purpose of DTAs is to avoid double taxation. It is not a purpose of DTAs to facilitate the complete avoidance of income tax in any jurisdiction, or to allow residents of a particular state to reduce the tax on their income to a level below that which would ordinarily be exacted by the state of residence. vi) It is a legitimate and important aim of UK public policy in fiscal affairs that a DTA should do no more than relieve from double taxation, and that a DTA should not be permitted to become an instrument by which persons residing in the UK avoid, or substantially reduce, the incidence of income tax that they would ordinarily pay on their income , including income earned from the exercise of a trade or profession. That is particularly the case where the means chosen to exploit the DTA in that way comprises artificial arrangements. ”
“… The clear purpose of Section 62 [Finance (No 2) Act 1987 ] was to amend the overseas partnership provisions in the 1970 Finance Act so as to remove the exemption conferred on persons like Mr Padmore by the UK Jersey Double Tax Treaty that is to say the UK resident partner in a foreign partnership relying on the terms of a Double Tax Treaty to exempt foreign partnership income from UK tax. ”

“ iv) Although the interpreter should assume that a statutory provision has some purpose, the purpose must be found in the words of the statute itself. The court must not infer a purpose without a proper foundation for doing so (Astall v HMRC (§ 44)). v) In seeking the purpose of a statutory provision, the interpreter is not confined to a literal interpretation of the words, but must have regard to the context and scheme of the relevant Act as a whole (WT Ramsay Ltd v Commissioners of Inland Revenue (1981) 54 TC 101, 184; Barclays Mercantile Business Finance Ltd v Mawson (§ 29)). … vii) In looking at particular words that Parliament uses what the interpreter is looking for is the relevant fiscal concept: (MacNiven v Westmoreland Investments Ltd[2001] STC 237 (§§ 48, 49)). ” 84. Miss Graham-Wells submitted that HMRC’s approach went beyond a purposive construction. They were seeking to re-write s 858(4) to refer to “a share of the income and/or the profit of the firm”
“ In the case of a person who carries on a trade, profession, or business in partnership with one or more other persons, a return under this section shall include each amount which, in any relevant statement, is stated to be his share of any income , loss, tax, credit or charge for the period in respect of which the statement is made. ”
