The retrospective nature of a statute may concern the whole provisions of the Statute, as where the commencement date so indicates; or may concern only a section of the statute – see Lauri v. Renad. (1892) 3 Ch. 402 at p. 421; Pardo v. Bingham, (1868 -69) 4 L.R.Ch. App. 735 at p. 739 and West v. Gwynne (1911) 2 Ch. 1. Where a statute is passed for the purpose of supplying an obvious omission in a former statute, the subsequent statute has relation back to the time when the prior Act was passed – see p. 395 of Craies on Statute Law. 7th Edition. Where a statute is in its nature declaratory, the presumption against construing it retrospectively is inapplicable – See A – G v. Theobald. (1890) 24 Q.B.D. 557. If by necessary implication from the language employed that the legislature intended a particular section to have a retrospective operation, the courts will give it such an operation- Lane v. Lane (1896) P. 133.
