Task: Question Answering
Input (English): Passage: After the control of Rupert's Land was passed from Great Britain to the Government of Canada in 1869, Manitoba attained full-fledged rights and responsibilities of self-government as the first Canadian province carved out of the Northwest Territories. The Legislative Assembly of Manitoba was established on 14 July 1870. Political parties first emerged between 1878 and 1883, with a two-party system (Liberals and Conservatives). The United Farmers of Manitoba appeared in 1922, and later merged with the Liberals in 1932. Other parties, including the Co-operative Commonwealth Federation (CCF), appeared during the Great Depression; in the 1950s, Manitoban politics became a three-party system, and the Liberals gradually declined in power. The CCF became the New Democratic Party of Manitoba (NDP), which came to power in 1969. Since then, the Progressive Conservatives and the NDP have been the dominant parties.Like all Canadian provinces, Manitoba is governed by a unicameral legislative assembly. The executive branch is formed by the governing party; the party leader is the premier of Manitoba, the head of the executive branch. The head of state, Queen Elizabeth II, is represented by the Lieutenant Governor of Manitoba, who is appointed by the Governor General of Canada on advice of the Prime Minister. The head of state is primarily a ceremonial role, although the Lieutenant Governor has the official responsibility of ensuring that Manitoba has a duly constituted government.The Legislative Assembly consists of the 57 Members elected to represent the people of Manitoba. The premier of Manitoba is Brian Pallister of the PC Party. The PCs were elected with a majority government of 40 seats. The NDP holds 14 seats, and the Liberal Party have three seats but does not have official party status in the Manitoba Legislature. The last provincial general election was held on 19 April 2016. The province is represented in federal politics by 14 Members of Parliament and six Senators.Manitoba's judiciary consists of the Court of Appeal, the Court of Queen's Bench, and the Provincial Court. The Provincial Court is primarily for criminal law; 95 percent of criminal cases in Manitoba are heard here. The Court of Queen's Bench is the highest trial court in the province. It has four jurisdictions: family law (child and family services cases), civil law, criminal law (for indictable offences), and appeals. The Court of Appeal hears appeals from both benches; its decisions can only be appealed to the Supreme Court of Canada.
