Section 82

When any order or regulation is made or direction or instruction is given under this Act, the Minister or other authority making such order or regulation or giving such direction or instruction shall cause notice of its effect to be given as soon as possible in such manner as he thinks necessary for bringing it to the notice of all persons who in his opinion ought to have notice of it, and such order, regulation, direction or instruction shall have effect as soon as notice as aforesaid has been given, without publication in the Gazette.

Without prejudice to any special provisions in this Act or in any rules or regulations made thereunder, a notice to be served on any person for the purposes of any section may be served by leaving it at, or by sending it by post in a letter addressed to that person at, his last or usual place of abode or place of business.

Any order or regulation made or any direction or instruction given under this Act may at any time during its continuance be cancelled by the person empowered to make such order or regulation or to give such direction or instruction, but without prejudice to the previous validity thereof or to anything done thereunder or to the power of that person to make a fresh order or regulation or give a fresh direction or instruction under such provisions.
