The Canadian legal system has its foundation in the English common law system with some influence from Scots Law,[citation needed] inherited from being a former colony of the United Kingdom and later a Commonwealth Realm member of the Commonwealth of Nations. The legal system is bi-jurisdictional, as the responsibilities of public (includes criminal) and private law are separated and exercised exclusively by Parliament and the provinces respectively. Quebec, however, still retains a civil system for issues of private law (as this domain falls within the exclusive jurisdiction of the provinces). Both legal systems are subject to the Constitution of Canada. Criminal prosecutions are conducted in the style of the British common law, as this jurisdiction falls exclusively to the federal government. The federal government also has jurisdiction over certain exclusive domains which are regulated exclusively by Parliament, as well as all matters and disputes between provinces. These generally include interprovincial transport (rail, air and marine transport) as well as interprovincial trade and commerce (which generally concerns energy, the environment, agriculture).
