William Sampson (26 January 1764 – 28 December 1836) was a lawyer and jurist who in his native Ireland, and in later American exile, identified with the cause of democratic reform. In the 1790s, in Belfast and Dublin he associated with United Irishmen, defending them in Crown prosecutions, contributing to their press and, according to government informants, participating on the eve of rebellion in their inner councils. In New York, from 1806 he won renown as a trial lawyer representing the abolitionist Manumission Society and disputing race as a legal disability; challenging the conspiracy charges against organised labor; and, in the name of religious liberty, establishing Catholic auricular confession as privileged. Maintaining that the tradition of common law denied citizens equal access to the law, and was a systematic source of injustice, Sampson pioneered the American codification movement.
