[15] Counsel for the appellant placed reliance upon the words "to remove any doubt, it is declared" in s 40A(3). The phrase "to remove any doubt" is, regrettably, an overused expression in legislation of the last decade. Commonly it is used as a bridging phrase between a general provision and an example that the draftsmen fears may not have been clearly enough covered by the general statement. The present instance would seem to be such an example. The general intention of the new provision seems to have been stated in s 40A(1) and s 40A(2). Section 40A(3) then states that "to remove any doubt, it is declared that the relationship of stepchild and step-parent does not stop merely because" of the stepchild's parent's death or of the deceased person's remarriage in the circumstances there set out. Further, the use of the words "it is declared" is far from determinative of the question whether legislation has retrospective effect[13]. The language in which Parliament may give retrospective effect to a change in the law is by no means circumscribed, but a good example which has not infrequently been used when such an effect was intended is a statement declaring that a certain provision is "and always has been" the law[14]. Perhaps such an assertion may these days be regarded as unduly bombastic, but if legislation is intended to affect existing rights and claims, it is not difficult for Parliament to say so[15]. In the present case we consider that the effect of the 1997 amendment was to change the law as distinct from stating what it is to be taken to have meant before the statute took effect, including at the time when the testator died.
