17. References to amended and re-enacted provisions
(1) Where in any enactment a reference is made to another enactment, the reference shall, except where the context otherwise requires, be deemed to include a reference to the last-mentioned enactment as the same may from time to time be amended.
(2) Where any enactment repeals and re-enacts, with or without modification, any provision of a former enactment, then, unless the contrary intention appears —
(a) any reference in any other enactment to the provision so repealed shall be construed as a reference to the provision so re-enacted;
(b) in so far as any subordinate legislation made or other thing done under the provision so repealed, or having effect as if so made or done, could have been made or done under the provision so re-enacted, it shall have effect as if made or done under that provision.
