1.1 As will be apparent from the Introduction, the sources of English Admiralty jurisdiction are diverse. A claimant seeking the framework must consider statute, civil procedure rules and judicial doctrine, and must not always expect to find reference from one source to another. The starting point is the Supreme Court Act 1981,1 but in some respects the Act simply triggers the need to define concepts used, and makes no reference at all to some elements which are inherent in the jurisdictional framework. It is, therefore, necessary both to sound a cautionary note as to the limits of the Supreme Court Act and to review the other sources to discover the framework or Admiralty jurisdiction.
