A taxable person shall – (a) in respect of supplies made by him, and (b) in respect of the acquisition by him from other member States of any goods, account for and pay VAT by reference to such periods (in this Act referred to as “prescribed accounting periods”) at such time and in such manner as may be determined by or under regulations and regulations may make different provision for different circumstances. 73 (1).

“14. Section 77(1)(a) effectively prevents the Commissioners from circumnavigating the 3 year period, except in the case of fraud or where the VATA specifically provides for it. This is the primary legislation. In applying the annual adjustment the Commissioners must, of necessity, carry out the calculation in the following quarter and apply the result to the prescribed accounting period immediately preceding that calculation. The legislature has decided that the appellant should be protected from any VAT liability which is more than 3 years old. The ‘prescribed accounting period’ under section 77(1)(a) for the purposes of this appeal is the period 4/00 to 3/01. That period is outside the 3 year cap. The annual adjustment is no more than a method of re-calculating the ‘prescribed accounting period’. It may be calculated in 6/01 but the Commissioners cannot assess other than for the periods 04/00 to 3/01 and in attempting to assess the period in 06/01 they will ‘widen the purpose of the Act’ (see Bennion above) which they cannot do under the interpretation rule of primary intention. The decision of Customs & Excise Commissioners–v- Laura Ashley Ltd is to be applied to this appeal and results in our allowing the appeal.”
“Underlying the concept of delegated legislation is the basic principle that the legislature delegates because it cannot exert its will in every detail. All it can do is lay down the outline. This means that the intention of the legislature, as indicated in the outline (that is the enabling Act), must be the prime guide to the meaning of the delegated legislation and the extent of the power to make it. In the Code this is referred to as the rule of primary intention…”
“28. For that exercise to be barred by section 77 it must be the case that the assessment is being raised more than 3 years after the prescribed accounting period concerned. It is therefore necessary to identify the “prescribed accounting period…concerned”
