This order establishes the legal framework for the extension of the Security Service Act 1989 to the Channel Islands. The document, issued by the British government, delineates the jurisdictional application of intelligence and security protocols within these specific territories, ensuring that the oversight mechanisms and operational mandates of the Security Service are legally binding in the Bailiwick of Jersey and the Bailiwick of Guernsey.

Legal practitioners and constitutional scholars view this order as a technical instrument necessary for the uniform application of national security law across British dependencies. It is considered a foundational document for understanding the legislative relationship between the United Kingdom and the Channel Islands regarding intelligence oversight.
