Jenkins was called to the bar at
Gray's Inn on 14 May 1924. He entered the colonial service in
Nyasaland in 1925, before becoming
Solicitor General of
Northern Rhodesia in 1936. He then served as
Attorney General of Fiji from 1938 to 1945; towards the end of his term, he was appointed
Chief Justice of Nyasaland on 8 November 1944. As Chief Justice, he headed a
commission of inquiry into a riot that had taken place at
Zomba Prison in November 1949. He was criticised by both
Sir Geoffrey Colby, the
Governor of Nyasaland, and the
Legislative Council, for allegedly paying undue attention to "matters of relatively minor significance" and of ignoring what they believed was the fundamental cause of the problem: the breakdown of discipline in the prison over the previous two years. Sometime before September 1953, he was appointed a Justice of Appeal on the
Kenya-based
Court of Appeal for Eastern Africa. He sat as one of the judges on
Jomo Kenyatta's unsuccessful appeal against his conviction for organizing the
Mau Mau movement. He was still reported as serving on the Court of Appeal as of 24 December 1954. ==References==
