Enforcement and execution of regulations
4.—(1) Subject to the provisions of paragraph (2) of this regulation, every health authority shall enforce and execute these regulations and shall exercise their functions through the medical officer and such other officers as they may authorise in that behalf, and shall make such inquiries and take such other steps as seem to them to be necessary for securing the proper exercise of those functions.
(2) Any two health authorities may agree, upon terms and conditions approved by the Secretary of State, that one of them shall undertake the enforcement and execution of and arrange for their authorised officers to enforce and execute the whole or specified provisions of these regulations in the district of the other, and for this purpose the district in which any such provision is so enforced and executed shall be deemed to be the district of the authority who enforces and executes it; and if their district is an approved port or a designated approved port and they so agree to enforce and execute in another district the provisions relating to Deratting Certificates and Deratting Exemption Certificates, the authorised officer for the district shall have authority to grant such Certificates in such other district.
