178.Subsection (1) prevents a local authority from doing anything under section 56 which it would otherwise be unable to do because of a “limiting provision”. Subsection (2) defines a limiting provision, which must be contained in an Act or other form of legislation.
179.Subsection (3) provides that a limiting provision must contain a positive restriction on the powers of the local authority, rather than merely failing to confer a power on it to do a thing.
