Karl Terrence Hudson-Phillips, ORTT, QC (20 April 1933 – 16 January 2014) was an Attorney-General of Trinidad and Tobago and a judge of the International Criminal Court. He was also lead counsel in the murder trial of Grenadian Prime Minister Maurice Bishop.
Hudson-Phillips attended Tranquillity School and Queen’s Royal College in Port of Spain, Trinidad, before going to England to read law at Selwyn College, Cambridge. In 1959, he was called to the bar at Gray's Inn, London. He returned to Trinidad and Tobago where he established a distinguished legal practice and was appointed a Queen's Counsel in 1970. He served as a Member of Parliament from 1966 to 1976. Between 1969 and 1973, he served as Attorney General and Minister of Legal Affairs. In this capacity, he was associated with the dreaded "Public Order Act" which was proposed by the People's National Movement (PNM) government in response to the Black Power riots and Army Mutiny of 1970. In 1973, he fell out of favour with then Prime Minister Eric Williams (for openly campaigning to replace Williams, who had spoken about retirement). This ended his political career in the PNM.
In 1974, Hudson-Phillips founded the National Land Tenants and Ratepayers Association of Trinidad and Tobago. In 1980, he founded the Organisation for National Reconstruction (ONR), a political party which contested the 1981 General Elections. Despite getting the second-highest vote tally in the election, the ONR failed to secure a single seat in Parliament. The ONR went on to form an accommodation with the National Alliance to contest the 1983 local government elections, and went on the merge with those parties to form the National Alliance for Reconstruction (NAR). Hudson-Phillips and Basdeo Panday, as the leaders of the two largest factions in what became the NAR, decided to step aside and allow A. N. R. Robinson, leader of one of the smaller parties, to become party leader. The NAR contested the 1986 general elections and won 33 of the 36 seats in Parliament. Hudson-Phillips did not take an active role in the party after the election.
