Opposition Leader in the Senate. Attorney-Generalship In 1969, Labor Leader Gough Whitlam appointed him Shadow Attorney-General and, when Labor won the 1972 election, he became Attorney-General and Minister for Customs and Excise. One of Murphy's more dramatic actions as Attorney-General was his sudden visit to the Melbourne headquarters of the Australian Security Intelligence Organisation (ASIO) on 16 March 1973. This came about because ASIO officers were unable to satisfy his requests for information concerning intelligence on supposed terrorist groups operated by Croatian Australians. Murphy's concern about the matter was heightened by the impending visit to Australia of the Yugoslav Prime Minister Džemal Bijedić. ASIO officers claimed not to be able to locate the file with which to properly brief Murphy. Murphy's belief was that, though a security service was an important part of the Australian social fabric, like any other arm of executive government it must be accountable to the relevant Minister. According to journalist George Negus, then Murphy's press secretary: "Lionel had asked for the files of the six most dangerous or subversive people in Australia". When the files arrived, Murphy found they were of several Communist Party (CPA) unionists and people such as CPA leader and peace movement activist Mavis Robertson. When he told Whitlam, they both laughed. Murphy was highly involved in the behind-the-scenes machinations and parliamentary debates around the appointment of DLP Senator Vince Gair as Ambassador to Ireland in 1974 (see Gair Affair), which preceded Whitlam's calling of a double dissolution election for May 1974. Murphy's most important legislative achievement was the Family Law Act 1975, which completely overhauled Australia's law on divorce and other family law matters. It established the principle of "no-fault divorce", in the face of opposition from the Roman Catholic Church and many other individuals and organisations. This act also established the Family Court of Australia. Civil Celebrants Murphy used an existing provision of the Marriage Act 1961 (Section 39C) to establish the Civil Marriage Celebrant programme. Using this provision he appointed about a hundred Civil Celebrants and urged them to provide marriage ceremonies of dignity, meaning and substance for non-church people. It was an initiative opposed by the Australian Labor Party, the public servants of his department and his personal staff. The civil celebrant program is almost entirely the result of one man’s vision. Murphy himself told me the story of how he was opposed by his own staff, the
