It shall be the duty of every local weights and measures authority to enforce the provisions of this Act within their area; and section 26 of the Act of 1968 (enforcing authorities) shall apply in relation to the enforcement of this Act, by such an authority, as it applies in relation to the enforcement of that Act.

The Council and the assay offices may also enforce the provisions of this Act.

Subject to subsection (7) below, the following provisions of the Act of 1968 shall apply in relation to the enforcement of this Act as they apply in relation to the enforcement of the Act of 1968, that is to say—
