Ronald King Murray, Lord Murray, PC (15 June 1922 – 27 September 2016) was a Scottish Labour politician and judge who rose to be a Senator of the College of Justice in 1979.
In April 1977, the Young Liberals' annual conference unanimously passed a motion to call on the Liberal leader (David Steel) to move for the impeachment of Murray for allegedly mishandling a murder case. Despite the urgings of the then chairman of the Young Liberals, Peter Hain, Steel did not table such a motion in the House of Commons, but Murray agreed that the Commons still have the right to initiate an impeachment motion.
Lord Murray was an active supporter of the World Court Project U.K., part of a worldwide network directed to obtaining a decision on the legality of using nuclear weapons. Success came in 1996, when the International Court of Justice ruled, in an advisory opinion, that the use of such weapons and the threat to use them would generally be illegal as contrary to international humanitarian law.
