Vice admiralty courts were juryless courts located in British colonies that were granted jurisdiction over local legal matters related to maritime activities, such as disputes between merchants and seamen.
American maritime activity had been primarily self-regulated in the early to mid-1600s. Smaller maritime issues were settled at court in local jurisdictions, prior to the establishment of courts to specialize in admiralty. In the colony of Massachusetts Bay, for instance, a maritime code to specialize in maritime legislation was created and in 1674 the Court of Assistants was established to determine all cases of admiralty. Typically the courts were presided over by a judge, unless it was deemed more suitable to be presided over by a jury. This was similar in Maryland, where a so-called 'Court of Admiralty' heard cases of maritime issues including sailor's wages, the carriage of goods and piracy. Originally these courts dealt primarily with commercial matters, and the judges which presided over them were appointed by the local population and were paid from the colonial treasuries. Their jurisdiction expanded, however, during the French and Indian War, to the condemnation of enemy ships including disposing of their possessions. It was not until the passage and the later stricter enforcement of the Navigation Acts by the British parliament from the 1650s through to the 1770s that the British government were granted more power over American maritime issues, as vice-admiralty courts began to enforce customs and hear criminal trials for smuggling.
In the 1700s, the British passed a variety of laws aimed at combating illegal smuggling in the American colonies. Americans had developed trade relationships with places such as southern Europe, the Netherlands and the West Indies, despite the fact that the Navigation Acts intended to give Great Britain a trade monopoly with its American colonies. The Molasses Act of 1733 had tried to tax molasses and non-British sugar, though it was largely unsuccessful. Shipowners who imported manufactured goods from the Netherlands smuggled these products in absolute secrecy, with Crown officials estimating that the annual value of manufactured goods smuggled equaled £500,000. British admiralty prepared commissions to authorize governors to erect vice-admiralty courts throughout the American colonies. In 1701, William Atwood was dispatched to preside as judge of the Admiralty for New Hampshire and the Jerseys. Due to firm colonial opposition, however, the task was practically impossible so he retired only a few years later. Other vice-admiralty judges in Pennsylvania and southern colonies faced similar difficulties as locally elected authorities strongly opposed the work they were sent to do.
