The initial lack of a clear majority in the Legislative Assembly for either party led to political instability for the first eighteen months of the term of the Fourth Legislature. The Liberal government of Premier Joly de Lotbinière depended on the support of the two Independent Conservatives. The Liberals agreed to elect one of the two independents,
Arthur Turcotte, as Speaker of the Assembly, a highly coveted position. Given the narrow majority and factiousness within the Liberal caucus itself, Joly de Lotbinière's government was uncertain of support from vote to vote in the Assembly, which affected his ability to implement major legislation. Several times, his government only stayed in office by a vote from Turcotte as Speaker. Joly de Lotbinière's government was also supported from time to time by
William Evan Price, who was nominally a Conservative but often voted in support of the government. On the Conservative side, the former house leader of the party in the Legislative Assembly,
Auguste-Réal Angers, lost his seat in the general election. This event badly weakened the authority of the leader of the party, former premier Boucher de Boucherville, who sat in the unelected Legislative Council. He was forced to cede the leadership of the party to
Joseph-Adolphe Chapleau, who became the Leader of the Opposition. The next event was the dismissal of Lieutenant Governor
Luc Letellier de Saint-Just by the new federal Conservative government of
Sir John A. Macdonald. Conservatives in Quebec, led by Chapleau, had been pressuring Macdonald to dismiss Letellier de Saint-Just as soon as the Macdonald government had defeated
Alexander Mackenzie's Liberal government in the
1878 federal election. Macdonald replaced Letellier de Saint-Just with an equally partisan Conservative,
Théodore Robitaille. Joly de Lotbinière was confident that he could win an election on the issues. He advised the new lieutenant governor, Robitaille, to dissolve the Assembly and call a general election. On October 30, 1879, Robitaille refused the dissolution. Joly de Lotbinière resigned and the Lieutenant Governor called on Chapleau to form a government. The Chapleau government was sworn in on October 31, 1878. Since he now had a working majority, Chapleau did not call an election, instead leading the Conservative government for the remaining term of the legislature. Like the Conservatives the previous year, the Liberals accused the Lieutenant Governor of performing a ''coup d'état''. == Legislative Assembly ==
