What is Common Law?

Judicial Precedent

Common law, also known as judicial precedent or judge-made law, is a body of law primarily developed through judicial decisions rather than statutes. It is largely based on precedent—judicial rulings made in previous similar cases.

The Core Principle

At its heart, common law is rooted in stare decisis, a Latin phrase meaning "to stand by things decided." This principle mandates that courts follow precedents established by previous decisions when adjudicating similar cases.

Case of First Impression

When a case presents a novel legal issue without existing precedent or clear legislative guidance, judges are empowered to resolve the matter, thereby establishing new precedent for future cases.

Core Principles

Stare Decisis

The doctrine of stare decisis is fundamental. It requires courts to adhere to established precedents, ensuring consistency and predictability in legal rulings. Decisions from higher courts or legislatures carry greater weight.

Judicial Adjudication

The presiding judge determines which precedents are applicable to the facts of a new case. This process involves careful research, analysis of statutes, and extraction of principles from prior judicial decisions.

Evolving Law

Common law is inherently adaptable. Courts can reinterpret and revise the law to align with changing social needs, political philosophies, and improved understanding, often through gradual, incremental steps.

Law in Motion

Gradual Development

Unlike the often lengthy legislative process, common law evolves incrementally. This gradual adaptation allows for the refinement of legal principles over time, minimizing disruptive breaks with established norms.

Judicial Interpretation

Judges interpret statutes and constitutional provisions, creating what is sometimes termed "interstitial common law." This involves analyzing legal texts and applying them to specific factual scenarios, shaping the law's practical application.

Beyond Maxims

While historically rooted in maxims, modern common law adjudication increasingly incorporates policy considerations, economics, social sciences, and insights from other jurisdictions, moving beyond mere "blind imitation of the past."

Common vs. Civil Law

Origins and Foundation

Common law systems trace their lineage to the English common law, emphasizing judicial precedent. Civil law systems, prevalent in continental Europe and elsewhere, derive from Roman law and are typically codified.

Role of Precedent

In common law, judicial decisions (precedent) are a primary source of law. Civil law judges generally give less weight to precedent, relying more heavily on comprehensive legal codes.

Adversarial vs. Inquisitorial

Common law systems typically employ an adversarial system where two opposing parties present their cases to a neutral judge. Civil law systems often use an inquisitorial system, where an examining magistrate plays a more active role in developing evidence.

Historical Roots

Norman Conquest Origins

Common law emerged from the practices of English royal courts following the Norman Conquest in 1066, gradually supplanting local customs and establishing a unified legal system across England.

Medieval Development

Key developments occurred through royal judges, the establishment of courts like the Court of Common Pleas, and the recording of decisions in plea rolls and Year Books, laying the groundwork for the doctrine of precedent.

  • Henry II (1154): Institutionalized common law by creating a unified system and jury system.
  • Royal Itinerant Justices: Judges traveled the country, hearing disputes and establishing common practices.
  • Doctrine of Precedent: Developed in the 12th and 13th centuries, binding judges to earlier decisions.

Global Propagation

The English legal system, including common law, was spread through the British Empire. Many former colonies adopted it, leading to its widespread use globally, often integrated into mixed legal systems.

Worldwide Reach

Commonwealth Influence

Common law forms the basis of legal systems in many Commonwealth nations, including Australia, Canada (except Quebec), India, New Zealand, and South Africa, reflecting historical ties to the British legal tradition.

United States System

The United States federal system and most states operate under common law principles, though specific areas like Louisiana retain civil law influences. The US Supreme Court plays a crucial role in shaping federal common law.

Mixed Jurisdictions

Approximately one-third of the world's population lives in common law jurisdictions or mixed systems that integrate common law with civil law traditions, demonstrating its adaptability and global significance.
