Admiralty courts, also known as maritime courts, are courts exercising jurisdiction over all maritime contracts, torts, injuries, and offences. King's Bench Division#Admiralty Court The Scottish court's earliest records, held in West Register House in Edinburgh, indicate that sittings were a regular event by at least 1556. Judges were styled "Judge Admiral" and received appointment at the hands of the Scottish High Admiral to hear matters affecting the Royal Scots Navy as well as mercantile, privateering and prize money disputes. From 1702 the judge of the court was also authorised to appoint deputies to hear lesser matters or to deputise during his absence. The Scottish court's workload was small until the mid-eighteenth century, with judges hearing no more than four matters in each sitting. After the 1750s the volume of cases rose until by 1790 it was necessary to maintain a daily log of decisions. The growth in caseload was related to increasing disputes regarding breaches of charter, including ship's masters seeking compensation for unpaid freight and merchants suing for damage to goods or unexpected port fees. Cases reflected Scotland's principal marine industries including the transshipment of sugar and tobacco and the export of dried fish, coal and grains. A smaller number of cases related to smuggling, principally brandy, and to salvage rights for ships wrecked on Scottish shores. The court ceased operation in 1832 and its functions were subsumed into the Court of Session, Scotland's supreme court for civil disputes. The sole survivor of the independent courts of admiralty is the Court of Admiralty for the Cinque Ports, which is presided over by the early-merged role of Judge Official and Commissary. This office is normally held by a High Court Judge who holds the appointment of Admiralty Judge. The jurisdiction of the Court of Admiralty of the Cinque Ports extends in an area with boundaries running from the Naze Tower, Essex along the shore to Brightlingsea, then to Shoe Beacon (or Shore Beacon), (to the east of Shoeburyness, Essex), across the mouth of the Thames Estuary to Shellness, Kent, and around the coast to Redcliffe, near Seaford, Sussex.
