During the two weeks the so-called "duumvirate" held office, Whitlam sought to fulfill those campaign promises that did not require legislation. Whitlam ordered negotiations to establish full relations with the People's Republic of China, and broke those with Taiwan. Legislation allowed the defence minister to grant exemptions from conscription. Barnard held this office, and exempted everyone. Seven men were at that time incarcerated for refusing conscription; Whitlam arranged for their liberation. The Whitlam government in its first days reopened the equal pay case pending before the Commonwealth Conciliation and Arbitration Commission, and appointed a woman, Elizabeth Evatt, to the commission. Whitlam and Barnard eliminated sales tax on contraceptive pills, announced major grants for the arts, and appointed an interim schools commission. The duumvirate barred racially discriminatory sports teams from Australia, and instructed the Australian delegation at the United Nations to vote in favour of sanctions on apartheid South Africa and Rhodesia. It also ordered the Australian Army Training Team home from Vietnam, ending Australia's involvement in the war; most troops, including all conscripts, had been withdrawn by McMahon.
