Many inferior courts have specialized functions, such as hearing only criminal law matters, youth matters, family law matters, small claims matters, "quasi-criminal" offences (i.e., violations of provincial statutes), or bylaw infractions. In some jurisdictions these courts serve as an appeal division from the decisions of administrative tribunals. Quebec also has a system of municipal courts that hear cases such as municipal and traffic infractions. Municipal courts in large cities such as Montreal and Quebec City may also hear minor criminal cases. Federal courts In addition to the Supreme Court of Canada, there are three civil courts created by the federal Parliament under its legislative authority under section 101 of the Constitution Act, 1867: the Federal Court of Appeal, the Federal Court, and the Tax Court of Canada. Federal Court of Appeal The Federal Court of Appeal hears appeals from decisions rendered by the Federal Court, the Tax Court of Canada and a certain group of federal administrative tribunals like the National Energy Board and the Canada Industrial Relations Board. All judges of the Federal Court are judges of the Federal Court of Appeal, and vice versa, although it is rare that a judge of one court will sit as a member of the other. The Federal Court of Appeal is a travelling court. The judges of the Court sit in panels of three, and hear cases in English and in French in 18 cities, from Vancouver to St. John's, including locations in northern Canada. Federal Court The Federal Court exists primarily to review administrative decisions by federal government bodies such as the immigration board and to hear lawsuits under the federal government's jurisdiction such as intellectual property and maritime law. It also has concurrent jurisdiction with the superior trial courts of the provinces to hear civil lawsuits brought against the federal government. The Federal Court also has jurisdiction to determine inter-jurisdictional legal actions between the federal government and a province, or between different provinces, provided the province in question has passed corresponding legislation granting the Federal Court jurisdiction over the dispute. The Federal Court have the power to review decisions, orders, and other administrative actions of most federal boards, commissions, and tribunals. That means most federal government administrative decisions can be challenged in the Federal Court. Also with the Federal Court, the system may refer back to questions of law, jurisdiction, or price to one of the federal courts at
