Lowe was appointed to the
Supreme Court of Victoria in January 1927, with the encouragement of his friend
Owen Dixon. This was with an annual salary of
£2500 (equivalent to A$207,400 in 2020). where his decision was upheld on appeal to the
Judicial Committee of the Privy Council. He also presided over "four major commissions of inquiry": • the 1940 inquiry into the
Canberra air disaster, • the 1942 inquiry into the
Bombing of Darwin, • the 1943 federal royal commission into the Minister for Labor
Eddie Ward's "
Brisbane Line" allegations, and • the 1949–1950
Royal Commission Inquiring into the Origins, Aims, Objects and Funds of the Communist Party in Victoria and Other Related Matters, into the
Communist Party of Australia. Communist activist
Ralph Gibson concluded that Lowe, "contrary to our fears and to the Government's hopes, displayed a certain genuine interest in Communist theory and a certain respect for evidence". Lowe retired from the court in 1964 after a record 37 years, presiding over his final trial in 1962. ==Other activities==
