The origin of many legal principles today comes from our common law British history. An Alberta case from 2006 traced a legal principle all the way back to the British decision in 1604 - Semayne's Case - establishing that a man's home is his castle.
The origin of many legal principles today - mostly now defined in legislation - comes from our common law British history.
For example, the Alberta case of R. v. Raponi, 2006 ABQB 593, has 339 paragraphs and detailed footnotes tracing relevant legal principles developed by prior court decisions.
This case is an example of the analysis and reasoning judges apply to every decision, even though the public might not see it. At paragraph 140, the foundation of this 2006 decision - that a seizure was unlawful - was based in part on the British decision from over four centuries ago: Semayne's Case (1604), which refers to, if not creates, the legal principle that "a man's home is his castle."
The Common Law Tradition in Canada
Canada's legal system is built on two great traditions: the common law tradition inherited from England (applied in every province except Quebec, which uses a civil law system derived from French law), and the constitutional framework established by the Constitution Act, 1867 and the Canadian Charter of Rights and Freedoms (1982).
The common law is judge-made law - principles developed over centuries through the decisions of courts. When a judge decides a case, that decision becomes a precedent that future courts in the same or lower jurisdictions are expected to follow. This doctrine is called "stare decisis" - Latin for "to stand by what has been decided." It gives the common law its remarkable stability and continuity across generations.
At the same time, the common law is not static. Courts at higher levels can "distinguish" older cases (find them inapplicable to new facts), "overrule" previous decisions when justice demands it, and develop new principles to address situations the older decisions never anticipated. This is how law evolves without requiring Parliament to pass new legislation for every new problem.
From Common Law to Legislation
Many of the most important legal principles in Canada today began as common law rules developed by judges - and were eventually codified (written into statutes) by Parliament or provincial legislatures. For example:
The right to be free from unreasonable search and seizure began as a common law protection of property (illustrated by Semayne's Case in 1604). It was later constitutionalized in section 8 of the Canadian Charter of Rights and Freedoms.
The law of contracts, negligence, and trusts all developed through centuries of judicial decisions before legislatures began supplementing them with statutes.
In BC family law, the old common law principle of "consortium" (a husband's legal right to his wife's services) has been abolished - replaced by the modern, equal framework of the Family Law Act (2011). But the process of identifying who qualifies as a "spouse" still draws on decades of case law interpreting what a "marriage-like relationship" means in practice.
Why This Matters for You
Understanding the deep roots of Canadian law helps explain why legal advice from an experienced lawyer matters so much. When you read the text of a BC statute - the Family Law Act, the Wills, Estates and Succession Act (WESA), the Business Corporations Act, or the Limitation Act - you are reading only part of the legal picture. Behind every section of every statute is a body of case law that fills in the gaps, defines the terms, and sometimes changes the meaning of words that seem clear on the surface.
For example, the FLA says a spouse is someone in a "marriage-like relationship" for two consecutive years. But what makes a relationship "marriage-like"? That question has been answered by dozens of BC court decisions over many years, each adding nuance to a concept the statute itself does not fully define.
A lawyer who knows the case law can advise you far more accurately than any reading of the legislation alone.
The Role of BC Courts
BC's court hierarchy mirrors this layered development of law:
The BC Provincial Court handles family law matters involving children, small claims, and certain criminal offences. Its decisions do not create binding precedent, but they reflect day-to-day application of the law.
The BC Supreme Court is a court of inherent jurisdiction - it can hear virtually any civil or family matter. Its decisions bind the Provincial Court and create precedent within BC.
The BC Court of Appeal reviews Supreme Court decisions. Its decisions bind all lower courts in BC.
The Supreme Court of Canada has final authority and its decisions bind courts across the country. When the SCC decides a family law or constitutional question, every court in Canada must follow that decision.

BC's legal system is based on the English common law tradition — courts follow the principle of stare decisis, meaning judges are bound to follow decisions made by higher courts in similar cases.
BC courts from lowest to highest are: BC Provincial Court, BC Supreme Court, BC Court of Appeal, and the Supreme Court of Canada — decisions from higher courts bind lower courts in BC.
Yes. While only BC appellate decisions are binding on BC trial courts, decisions from other Canadian provinces and even courts in similar common law countries like England or Australia are frequently considered as persuasive authority.
Statute law is written legislation passed by the BC Legislature or Parliament (such as the Family Law Act), while common law is judge-made law developed through court decisions — both apply in BC courts.
