Separation of powers is the division of a state's government into branches, each with separate, independent powers and responsibilities, so that the powers of one branch are not in conflict with others. The typical division into three branches of government, sometimes called the trias politica model, includes a legislature, an executive, and a judiciary. It can be contrasted with the fusion of powers in monarchies, but also parliamentary and semi-presidential systems where there can be overlap in membership and functions between different branches, especially the executive and legislative.

Separation of powers is a political doctrine originating in the writings of Charles de Secondat, Baron de Montesquieu in The Spirit of the Laws, in which he argued for a constitutional government with three separate branches, each of which would have defined abilities to check the powers of the others. This philosophy heavily influenced the drafting of the United States Constitution, according to which the Legislative, Executive, and Judicial branches of the United States government are kept distinct in order to prevent abuse of power. The American form of separation of powers is associated with a system of checks and balances.

[1997] 3 S.C.R. 3 is a leading opinion of the Supreme Court of Canada in response to a reference question regarding remuneration and the independence and impartiality of provincial court judges. Notably, the majority opinion found all judges are independent, not just superior court judges and inferior court judges concerned with criminal law, as the written constitution stipulates. Unwritten constitutional principles were relied upon to demonstrate this, indicating such principles were growing in importance in constitutional interpretation. The reference also remains one of the most definitive statements on the extent to which all judges in Canada are protected by the Constitution.

In most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, and highcourt of appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court are binding on all other courts in a nation and are not subject to further review by any other court. Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts. A Supreme Court can also, in certain circumstances, act as a court of original jurisdiction, however, this is typically limited to constitutional law.

This enables the constitution to be easily changed as no provisions are formally entrenched.

It is crucial as it serves as a foundation for the rule of law and democracy.
