History
Common Law
Quick fact
The doctrine of precedent means that a decision in a higher court is binding on lower courts, creating a hierarchy that ensures consistency. Over time, a series of decisions forms a body of law—hence the term 'common law'—which is as powerful as any statute.
Why this is interesting
You've likely heard of 'judge-made law,' but did you know that in many countries, a single court decision can shape the law for centuries? How does a court ruling become a rule that binds millions?

Understanding Common Law
Imagine two neighbors disputing a property boundary. The judge decides based on principles of fairness and prior cases. That decision becomes a 'precedent.' When a similar dispute arises later, judges are expected to follow that precedent to ensure fairness and predictability. This is the core of common law: law built from the ground up, one case at a time. It contrasts with civil law, where a comprehensive code dictates outcomes. In common law, the judge is not just an enforcer of rules; they are a participant in creating them. This system originated in medieval England, where royal courts traveled the country to settle disputes, gradually unifying local customs into a single, 'common' law.
A deeper explanation
The underlying mechanism is the principle of 'stare decisis'—Latin for 'to stand by things decided.' Courts are arranged in a hierarchy, and higher courts' decisions bind lower courts. When a court encounters a new issue, it looks to prior cases for guidance. If a precedent is on point, it must be followed. If not, the judge creates a new precedent, which then becomes part of the law. This creates a body of case law that evolves organically as societies change. The system's strength lies in its flexibility: it can adapt to new situations through judicial reasoning, and it ensures consistency and fairness through precedent. While statutes passed by legislatures can override judge-made law, the common law tradition emphasizes the judiciary's vital role in interpreting and refining those statutes, leading to a symbiotic relationship between legislation and judicial decisions.
