From how many sources does this constitution, on which the Constitution of Alberta is modeled, draws?
Constitution of the United Kingdom The United Kingdom does not have one specific constitutional document named as such. Instead, the so called constitution of the United Kingdom is a sum of laws and principles that make up the body politic of the UK. This is sometimes referred to as an "unwritten" or uncodified constitution. The British constitution primarily draws from four sources: statute law (laws passed by the legislature), common law (laws established through court judgments), parliamentary conventions, and works of authority. Similar to a written constitution, this sum also concerns both the relationship between the individual and the state, and the functioning of the legislature, the executive and judiciary.
Law of Canada The Canadian legal system has its foundation in the English common law system, 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).
