Scottish Adjacent Waters Boundaries Order 1999
UK Statutory Instrument 1999 No. 1126

The Scottish Adjacent Waters Boundaries Order 1999 (SI 1999/1126) is a statutory instrument of the United Kingdom government, defining the boundaries of internal waters, territorial sea, and British fishing limits adjacent to Scotland. It was introduced in accordance with the Scotland Act 1998, which established the devolved Scottish Parliament.
Defining jurisdictions
The territorial waters defined come under the jurisdiction of Scots law, and are also used for defining the area of operation of the Scottish Government (including the Marine Directorate), SEPA, and other Scottish Government agencies and public bodies.
The territorial waters defined as not being Scottish waters come under the jurisdiction of either English law or Northern Ireland law. Because the order defines the territorial limits of the three separate jurisdictions, it comprises a piece of constitutional law in the constitution of the United Kingdom.
Scottish waters
Scottish waters is a colloquial term which can refer to different sea areas, including:
Internal waters and territorial sea adjacent to Scotland. ("Scotland" as defined in the Scotland Act 1998)
British Fishing Limits adjacent to Scotland. ("The Scottish Zone" as defined in the Scotland Act 1998)
The UK continental shelf limits adjacent to Scotland. (Part of the "Scottish offshore marine region" as defined in the Marine and Coastal Access Act 2009)
Differences with existing boundaries
The maritime boundary adopted by the order is an equidistant boundary. This differed from the boundary established by the Civil Jurisdiction (Offshore Activities) Order 1987 (SI 1987/2197) which defined a straight line border between Scotland and England in the North Sea along the latitude of 55° 50' 00"N.
No oil fields were affected by this change as the new boundary only applied to fishing and had no impact on reserved matters.
