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.
Copyright law of Canada The copyright law of Canada governs the legally enforceable rights to creative and artistic works under the laws of Canada. Canada passed its first colonial copyright statute in 1832 but was subject to imperial copyright law established by Britain until 1921. Current copyright law was established by the Copyright Act of Canada which was first passed in 1921 and substantially amended in 1988, 1997, and 2012. All powers to legislate copyright law are in the jurisdiction of the Parliament of Canada by virtue of section 91(23) of the Constitution Act, 1867.
