All authorities are enforcing authorities and accept that, notwithstanding the Home Authority Principle, each local authority retains its ultimate statutory responsibility for the enforcement of the law.

However it should:

• liaise with the home authority before embarking on detailed investigations or legal actions;
• communicate with the home authority in specific terms, preferably in writing, indicating details of the issue;
• the nature of the assistance required and whether or not, it is content to leave action to the judgement of the home authority;
• ensure that the relevant documents, formal cautions, decisions to prosecute and the results of legal proceedings are notified to the home authority;
• take account of advice given to a business by the home or originating authority.
