Editing Constitution (section)

====Mixed constitutions====
Some constitutions are largely, but not wholly, codified. For example, in the [[Constitution of Australia]], most of its fundamental political principles and regulations concerning the relationship between branches of government, and concerning the government and the individual are codified in a single document, the Constitution of the Commonwealth of Australia. However, the presence of statutes with constitutional significance, namely the [[Statute of Westminster 1931|Statute of Westminster]], as adopted by the Commonwealth in the [[Statute of Westminster Adoption Act 1942]], and the [[Australia Act 1986]] means that Australia's constitution is not contained in a single constitutional document.{{citation needed|date=July 2020}} It means the Constitution of Australia is uncodified,{{dubious|date=July 2020}} it also contains [[Constitutional convention (political custom)|constitutional conventions]], thus is partially unwritten.

The [[Constitution of Canada]] resulted from the passage of several [[British North America Acts]] from 1867 to the [[Canada Act 1982]], the act that formally severed British Parliament's ability to amend the Canadian constitution. The Canadian constitution includes specific legislative acts as mentioned in section 52(2) of the [[Constitution Act, 1982]]. However, some documents not explicitly listed in section 52(2) are also considered constitutional documents in Canada, entrenched via reference; such as the [[Proclamation of 1763]]. Although Canada's constitution includes [[List of Canadian constitutional documents|a number of different statutes, amendments, and references]], some constitutional rules that exist in Canada are derived from unwritten sources and constitutional conventions.

The terms ''written constitution'' and ''codified constitution'' are often used interchangeably, as are ''unwritten constitution'' and ''uncodified constitution'', although this usage is technically inaccurate. A codified constitution is a single document; states that do not have such a document have uncodified, but not entirely unwritten, constitutions, since much of an uncodified constitution is usually written in laws such as the [[Basic Laws of Israel]] and the [[Parliament Acts 1911 and 1949|Parliament Acts]] of the United Kingdom. Uncodified constitutions largely lack protection against amendment by the government of the time. For example, the U.K. [[Fixed-term Parliaments Act 2011]] legislated by simple majority for strictly [[Fixed-term election|fixed-term parliaments]]; until then the ruling party could call a general election at any convenient time up to the maximum term of five years. This change would require a constitutional amendment in most nations.
