Rule making power enables government to prescribe rules, permit limited retrospectivity, and provide for penalties under the Act. Section 164 authorises the Government, on the Council's recommendation, to make rules by notification to implement the Act, including rules on matters required or permitted to be prescribed and consequential provisions. The rule making power expressly permits rules to have retrospective effect not earlier than the Act's commencement and allows rules to provide for penalties for contraventions subject to an upper monetary ceiling.
