Murray was called to the bar at the Inner Temple in 1888, returned to South Australia and was associate to Sir Samuel Way until 1891, when he began practising as a barrister, initially in partnership with William Ashley Magarey as Murray & Magarey. He was soon successful, and in 1906 became a KC, the first Adelaide graduate to obtain this distinction. In 1909 he paid a visit to England and took his LL.M. degree, and in 1912 he was appointed a judge of the Supreme Court of South Australia. He had been on the council of the university since 1891, and in 1915 was appointed vice-chancellor. In 1916 he succeeded Sir Samuel Way as chief justice of South Australia and later the same year became chancellor of the university. His interest in educational problems and the university was shown in many ways, and his benefactions included £1000 for the building fund of the university in 1920, £2000 for general purposes in 1931, and £10,000 for a men's union building in 1936. He also renounced his life interest in the estate of his sister the value of which was estimated at £45,000. This was left to the university in 1936. Murray administered the government of South Australia on numerous occasions in the absence of the Governor. Murray visited Europe again in 1935, and died at Adelaide following an operation for appendicitis on 18 February 1942; he was buried privately beside his sister in St George'sChurch of England cemetery, Magill. He was created K.C.M.G. in 1917. He was unmarried.
Summary and legacy
Murray had a reserved manner, at times giving the impression that he was cold in his outlook. However, this was not the case as Murray was in reality warm-hearted, broad-minded, and generous, always anxious to assist deserving causes so long as it could be done without ostentation. As chancellor of the university for 25 years, he was held in honour and affection by teaching staff and students alike. As a counsel Murray was not a dramatic pleader, but was clear and systematic in his presentation of technical cases, and masterly in the marshalling of his arguments, excelling in equity cases. As a judge he showed himself to be an able lawyer with a wide knowledge of human nature, encouraging timid witnesses, and dealing firmly with those of a prevaricating or shifty character. His outlook at times may have seemed severe, but this came from his determination to carry out the law, and he was always diligent and painstaking. He was much esteemed by the legal profession. He was lieutenant-governor of South Australia for practically the whole period of his chief justiceship, on many occasions administered the government, and his experience was always available to incoming governors. He sought neither praise nor public approval, but at the time of his death he was the most distinguished South Australian of his period. In 1908 he endowed the University of Adelaide with £1,000 to establish the Tinline Scholarship in History in recognition of the family of his mother, born Margaret Tinline. Every year at St. Peter's College the house with the highest performance and effort in house events is awarded the George Murray shield.
