References to repealed Act to apply to substituted Act
9When an enactment is repealed or a regulation revoked, and other provisions are substituted by way of amendment, revision or consolidation, any reference in an unrepealed Act, or in any instrument or document, rule, order, regulation, by-law or ordinance made thereunder, to such repealed enactment or revoked regulation, shall, as regards any subsequent transaction, matter or thing, be held and construed to be a reference to the provisions of the substituted enactment, regulation or amendment relating to the same subject matter as such repealed enactment or revoked regulation; but where there is no provision in the substituted enactment or regulation relating to the same subject matter, the repealed enactment or revoked regulation shall stand good, and be read and construed as unrepealed or unrevoked in so far, but in so far only, as is necessary to support, maintain, or give effect to, such unrepealed Act, or such instrument, document, rule, order, regulation, by-law or ordinance made thereunder.
