Changing roles,changing rules: procedural development and difference in Australian State upper houses

The status and potential of Australian State upper houses have been enhanced, to a greater or lesser degree from State to State, by electoral system change over the past half century. The purpose of this article is to determine the extent to which those changes have been accompanied by efforts on the part of the upper houses to improve performance of their core functions of review of legislation and scrutiny of government. The focus is the parliamentary procedures that facilitate performance of these functions. As well as surveying innovation in, and use of, relevant parliamentary procedures in the five upper houses, the article explains differential outcomes in innovation and effectiveness across the States in terms of the consequences of choice of electoral system and size of upper house membership.
