279.Section 60 provides for a power to make regulations to amend provisions which refer to a date when a provision comes into force so that instead it includes the actual date on which the provision in question came into force. This avoids the reader having to separately ascertain the date on which the provision came into force. Subsection (1) relates to the date of liability for expenses in relation to enforcement notices (section 158B of the 1997 Act inserted by section 43(3) of the Act). Subsection (2) relates to the date from which all directions are required to be published in accordance with the new section 275B of the 1997 Act inserted by section 49 of the Act, and subsection (3) refers to the infrastructure levy “sunset clause” in section 58 of the Act.
