The 25th Alberta Legislative Assembly was in session from April 9, 2001, to October 25, 2004, with the membership of the assembly determined by the results of the 2001 Alberta general election held on March 12, 2001. The Legislature officially resumed on April 9, 2001, and continued until the fourth session was prorogued and dissolved on October 25, 2004, prior to the 2004 Alberta general election on November 22, 2004. Alberta's twenty-fifth government was controlled by the majority Progressive Conservative Association of Alberta, led by Premier Ralph Klein. The Official Opposition was led by Ken Nicol of the Liberal Party. The Speaker was Ken Kowalski. With the exception of the three MLAs listed below, all members held their seats until dissolution of the legislature. History The 25th Legislative Assembly was ushered in with a massive Progressive Conservative majority, with Alberta being dubbed Ralph's World following the 2001 general election. The official opposition Liberals began a turbulent period that would see the party go through four leaders. The third party Alberta New Democrats also changed leaders in July 2004 with the retirement of Raj Pannu and choice of Brian Mason as new leader. Towards the end of the legislature for the first time since 1985, a new party caucus was formed. Edmonton-Norwood MLA Gary Masyk would cross the floor to the Alberta Alliance which had been formed in 2002 and registered in 2003 creating the caucus for that party. His reason for leaving was the Premier's interference in the 2004 federal election that coincided with a sharp decline in poll numbers that kept the federal Conservatives from winning the election. His electoral district was also abolished in the 2004 Alberta Boundary Re-distribution. Support the Progressive Conservatives softened through the reign of the Assembly but still remained high during the 2004 general election. Bills Adult Interdependent Relationships Act The Adult Interdependent Relationships Act (S.A. 2002, c. A-4.5) was passed by the Alberta Legislature on December 4, 2002, and proclaimed in force on June 1, 2003. The act did not amend Alberta's Marriage Act, but did amend 69 other Alberta laws following the 1999 landmark Supreme Court of Canada ruling in the case of M. v. H., which essentially required all provinces to extend the benefits of common-law marriage to same-sex couples, under the equality provisions of Section Fifteen of the Canadian Charter of Rights and Freedoms.
