 The Continental Shelf Act 1964 and the Continental Shelf (Jurisdiction) Order 1968 defined the UK North Sea maritime area to the north of latitude 55 degrees north as being under the jurisdiction of Scots law meaning that 90% of the UK's oil resources was considered under Scottish jurisdiction.In addition, section 126 of the Scotland Act 1998 defined Scottish waters as "the internal waters and territorial sea of the United Kingdom as are adjacent to Scotland".This was subsequently amended by the Scottish Adjacent Waters Boundary Order 1999 which redefined the extent of Scottish waters and Scottish fishery limits.
