Parliament of Australia
From 1901 to 1949, the House consisted of either 74 or 75 members (the Senate had 36). Between 1949 and 1984, it had between 121 and 127 members (the Senate had 60 until 1975, when it increased to 64). In 1977, the High Court ordered that the size of the House be reduced from 127 to 124 members to comply with the nexus provision. In 1984, both the Senate and the House were enlarged; since then the House has had between 148 and 150 members (the Senate has 76).
Australian Senate committees
Senate committees can be affected by the party composition of the Senate. The Clerk of the Senate, Harry Evans, argued that a government majority of seats in the Senate resulted in limitations on what the committees inquired into, and how readily governments responded to their queries and requests for information. Statistics published by centrist political party the Australian Democrats have been used to support the contention that committee operations have been inhibited by government control of the Senate, particularly in respect of selection of topics for committee inquiry. However Senator Minchin, the leader of the government in the Senate in the mid-2000s, pointed out that their political rivals had previously cut off debate on more bills in the Senate than had his government.
