John Clarke MacDermott, Baron MacDermott, MC, PC, PC (NI), Northern Irish politician, barrister, and judge, dies at his home in Belfast on July 13, 1979. He serves as Attorney General for Northern Ireland, a Lord of Appeal in Ordinary, and Lord Chief Justice of Northern Ireland. He is the first law lord to be appointed from Northern Ireland.
MacDermott is born in Belfast on April 12, 1896, the third surviving son and sixth of seven children of the Reverend John MacDermott DD, a Presbyterian clergyman who is minister of Belmont and moderator of the Presbyterian Church in Ireland, and of his wife Lydia Allen MacDermott (née Wilson), the daughter of a Strabane solicitor. He is educated at Campbell College, Belfast, from where he wins a scholarship to read Law at the Queen’s University Belfast (QUB) in 1914.
During the World War I, he serves with the machine gun battalion of the 51st (Highland) Division in France, Belgium and Germany, winning the Military Cross in 1918 and reaching the rank of Lieutenant. After the war he is called to the Bar of Ireland in 1921.
Eight years later MacDermott is appointed to determine industrial assurance disputes in Northern Ireland, and in 1931 becomes a lecturer in Jurisprudence at Queen’s University Belfast, teaching for four years.
In 1936, he is made a King’s Counsel, and two years later he is elected to the Northern Ireland House of Commons as an Ulster Unionist member for Queen’s University.
In 1940, MacDermott is appointed Minister of Public Security in the Government of Northern Ireland, and the following year becomes the Attorney General for Northern Ireland. He is succeeded in this post by William Lowry, whose son, Lord Lowry, would eventually succeed MacDermott as Lord Chief Justice. In 1944, he resigns his parliamentary seat on appointment as a High Court Judge for Northern Ireland, and three years later, on April 23, 1947, is made a Lord of Appeal in Ordinary, becoming a life peer as Baron MacDermott, of Belmont in the city of Belfast.
MacDermott returns from the House of Lords to take up his appointment as Lord Chief Justice of Northern Ireland. His successors to the latter office become Law Lords subsequently. Whilst Lord Chief Justice, he is affectionately known as “the Baron.”
In 1977, aged over eighty, MacDermott offers to redeliver a lecture at the Ulster College, which had been interrupted by a bomb meant for him and which had severely wounded him.
Having been made a Northern Ireland Privy Counsellor seven years earlier, MacDermott is sworn of the British Privy Council in 1947.
Four years later, in 1951, MacDermott is appointed Lord Chief Justice of Northern Ireland, a post he holds for twenty years. He is also Pro-Chancellor of his alma mater from 1951 to 1969. In 1958, he chairs the commission on the Isle of Man Constitution. He dies at his home in Belfast on July 13, 1979.
In 1926, MacDermott weds Louise Palmer Johnston, later Lady MacDermott. Their son, Sir John MacDermott, is also sworn into the British Privy Council in 1987, as a Lord Justice of Appeal in Northern Ireland. He later became a Surveillance Commissioner for Northern Ireland.
