Seerecht
Admiralty law governing relations between entities that operate vessels on the oceans is dealt with by special courts. There was a High Court of Admiralty in London and Vice Admiral's Courts in other ports. Originally they dealt with administrative and naval matters but then included piracy cases (from 1700). By the 16th century they had wide powers but these were later reduced until restored in the 19th century. Trade disputes generally are dealt with by the commercial court. The admiralty laws were a prominent feature in causing the American Revolution.
