The Service's enforcement jurisdiction extends across the entire Bailiwick and encompasses the Islands of Guernsey, Alderney, Herm, and Sark. In common with many communities, a historical development of parish constables formed the system of
Law of Guernsey relating to rubbish collection and data protection laws. Certain laws affecting Guernsey can be imposed on Guernsey by the United Kingdom government and are registered as Guernsey laws to extend them to the Bailiwick. Examples include the Landmines Act 1998 ( becoming the Landmines Act 1998 (Guernsey) Order 2000) and the Police Act 1997. There have been many cases in history of Guernsey simply not registering Parliamentary laws which has the effect of nullifying them. Convention requires Parliamentary laws to (a) not go beyond the prerogative powers over the Islands and (b) should be consonant with aspects of modern law.
