case. Judicial career In February 1975, Whitlam appointed Murphy to a vacancy on the High Court of Australia. He was the first serving Labor politician appointed to the Court since Dr. H. V. Evatt in 1931 and the appointment was bitterly criticised. He resigned from the Senate on 9 February 1975 to take up the appointment. Murphy was the last High Court justice to have served as a Member of Parliament, and the last politician appointed to the High Court. Additionally, Murphy was one of only eight justices of the High Court to have served in the Parliament of Australia prior to his appointment to the Court, along with Edmund Barton, Richard O'Connor, Isaac Isaacs, H.

Although it did not become a constitutional requirement until 1977, it had been long-standing convention that a Senate casual vacancy be filled by a person from the same political party. However, on 27 February 1975, the Premier of New South Wales, Tom Lewis, controversially appointed Cleaver Bunton, a person with no political affiliations, to replace Murphy in the Senate, beginning the chain of events which led to the 1975 Australian constitutional crisis. These events provided the impetus for the 1977 constitutional change that ensures such an appointment cannot be repeated, although a State Government can still achieve a similar result by declining to fill a Senate vacancy. Soon after his appointment to the bench, Murphy visited Justice Menzies' old chambers in Taylor Square, which would now be his. Staring at the volumes of British law reports on the shelves behind his desk, he said, "I want all of these to go". He replaced them with decisions from the Supreme Court of the United States. Court cases and death In the summer of 1983/84, during the term of the first Hawke government, both The National Times and The Age published transcripts of telephone conversations illegally recorded from 1979-81 by the New South Wales Police. Although not then authenticated, they were allegedly between Murphy and Sydney lawyer Morgan Ryan, who in 1982 faced charges of forgery and conspiracy. In July 1985, Murphy was initially convicted on one of two charges of attempting to pervert the course of justice, over new allegations made by Clarrie Briese, the Chief Magistrate of New South Wales, that Murphy had attempted to influence a court case against Morgan Ryan, whom Murphy referred
