18. (1) Notwithstanding anything in Chapter 2 or 3, for the purposes of the operation of any provision of either Chapter in relation to a public servant to whom section 6C(3) of the No. 2 Act of 2009 applies, every one of the restorations of the amounts of the annual remuneration provided for in that section 6C(3) shall be deemed to have taken effect—

(a) in the case of a provision of Chapter 2, before 1 January 2018, and

(b) in the case of a provision of Chapter 3, before 1 October 2018,

and with the effect that it is by reference to the notional amount of the annual remuneration which that public servant, by virtue of such deeming, enjoys (the “notional annual remuneration”) - rather than the actual annualised amount of his or her basic salary at the particular time - that the computation of the percentage increase specified in section 7 or 12, as the case may be, is to be made.

(2) In particular, subsection (1), as it applies to section 7, has effect so that the operation, required by section 7(1)(b), of applying, on 1 October 2018, the percentage increase specified in section 7(1)(b) is performed by reference to the amount of the notional annual remuneration as that remuneration stands increased by the percentage specified in section 7(1)(a).
