Sir Hector Horace Hearne (23 February 1892–31 December 1962) was a Judge.
He was Appeal Justice, the West African Court of Appeal (1954–1955), Chief Justice, Kenya (1951–1954), Chief Justice, Jamaica (1945-1950/1951), Puisne Judge, Ceylon (1937–1944), Puisne Judge, Tanganyika Territory (1934-1936/1937) and a non-practicing Barrister.
After holding the appointments of first class Magistrate, District Magistrate, Senior Magistrate and Acting Puisne Judge, Hearne was appointed as a Puisne Judge (High Court Judge), Tanganyika Territory (East Africa) in 1933/1934, where he acted as Chief Justice in 1935 and 1936.
As a Puisne Judge of the Supreme Court of Ceylon, the judgments of Mr Justice Hearne were subject to at least two appeals to the Privy Council in London. The reported cases appear in the English law reports. They are: Abdul Hameed Sitti Kadija v De Saram  AC 208 and Vander Poorten v Settlement Officer  AC 271. The former case concerned construction of a will; the latter concerned the Waste Lands Ordinance, No 1 of 1897, ss 18, 20. The second case is probably of historical interest only; the first may conceivably still be a relevant authority (i.e. part of English caselaw). In the first case, Hearne J (as he is cited in the law reports) was one of the majority in the Supreme Court which made the decision which was appealed to the Privy Council. A fellow High Court Judge dissented; and the Privy Council upheld the dissenter, thus finding that Hearne J and his colleagues were in error. The second appeal was also allowed, another finding that Hearne J and his colleagues had erred.
Hearne was created a Knight in 1946, for services to the Crown during the Mau Mau Uprising and was known thereafter as Sir Hector. Unlike a number of his fellow judges, he was never made King's (or Queen's) Counsel. He was an honorary Judge in the Queen's Bench Division.
Hearne was escorting the Princess Elizabeth to a dinner at the Tree Tops Safari Hotel in Kenya on the night her father, King George VI, died and she became Queen Elizabeth II. She returned immediately to the UK, escorted by Hearne.
Horace held the position of Chief Justice in Kenya until 1954 when he became an Appeal Justice of the West African Court of Appeal, a position he held between 1954 and 1955. He was Acting President of the West African Court of Appeal in 1958.
Horace's speciality was Roman Law. Horace's last entry in the Law List as a barrister was 1963. (It is indicated at the head of the list for that year that non-subscribing barristers will not be included in the list except by application).
He married Winifred Combridge (died 1959), and they had two sons. He died on 31 December 1962 at the age of 70.
