Constitutional Council (France)
The Government of France consists of an executive branch (President of the Republic, Prime Minister, ministers, and their services and affiliated organizations), a legislative branch (both houses of Parliament), and a judicial branch. The judicial branch is, unlike for instance the federal judiciary of the United States under the Supreme Court, not organized into a single hierarchy (administrative courts fall under the Council of State, civil and criminal courts under the Court of Cassation), and some of its entities also have advisory functions. For historical reasons there has long been a hostility to having anything resembling a "Supreme Court"—that is, a powerful court able to quash legislation. Whether the Council is a court is a subject of academic discussion, but some scholars consider it the supreme court of France.
Court system of Canada
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-jurisidctional 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. Also the Federal Courts have the power to review decisions, orders, and other administrative actions of most federal boards, commissions, and tribunals. That means most federal government 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 any stage of proceeding.
