In the vast world of legal research, understanding case law is fundamental. Case law, often used interchangeably with common law, forms a critical part of the legal system in many countries, including the United States. It is a body of law established through the judicial decisions of courts and similar tribunals, rather than through constitutions, statutes, or regulations. These past decisions, or “precedents,” are based on the detailed facts of resolved legal cases.
The term “case law” refers to the body of law created by judges’ decisions in court. It is also known as “judge-made law”. While statutory law is enacted by legislative bodies and regulatory law is set by executive agencies, case law develops when judges interpret existing statutes and apply precedents to specific situations. This process provides clarity and guidance on how laws are interpreted in real-world scenarios.
A core principle of common law systems is stare decisis, a Latin phrase meaning “let the decision stand”. This principle binds judges to follow past decisions in similar cases, ensuring consistency and fairness in rulings. A decision by a higher court is binding on lower courts within the same jurisdiction. For example, a decision by the U.S. Supreme Court is binding on all federal courts, as well as on state courts regarding federal and constitutional law.
Legal Expert Tip: When a case has no clear precedent, known as a “case of first impression,” judges have the authority to resolve the issue and establish a new precedent. This is how case law evolves and adapts to new legal challenges.
Understanding where to find case law begins with the structure of the court system itself. The hierarchy generally follows a three-tiered model from the state to the federal level:
A decision from a higher court is binding on lower courts in the same jurisdiction, but a decision from a different jurisdiction may only be considered as a persuasive authority. For example, a court in New York is not strictly bound by case law from California, but might consider it if there is no binding precedent in its own jurisdiction.
Fortunately, a wide range of legal resources, both free and subscription-based, are available to help legal experts and students locate and analyze case law. These resources provide access to court opinions, statutes, and legal articles.
Cautionary Note: While these resources provide extensive information, it is crucial to verify the current applicability of any case law you find, as decisions can be overturned by higher courts or become outdated. Always check for the latest versions and official sources.

Navigating the complex landscape of legal research requires a solid understanding of what case law is and where to find it. Here are the key takeaways:
This blog post explores the critical role of case law in the U.S. legal system. We explained how court decisions create a body of precedent that guides future rulings and explored the hierarchical structure of U.S. courts, from the Supreme Court down to state appellate courts. The guide also provided a curated list of top online resources like FindLaw and Justia, which offer free access to millions of legal opinions, empowering legal professionals and students to conduct effective research.
Case law is based on judicial decisions and precedents, while statutory law is written and enacted by a legislative body, such as Congress. In case of a conflict, statutory law generally prevails over case law.
Binding precedent refers to a previous court decision that a lower court is required to follow when deciding a similar case. For example, decisions by the U.S. Supreme Court are binding on all lower federal and state courts.
While free resources like Justia and Google Scholar are invaluable for legal research, they may not be as comprehensive or up-to-date as paid subscription services. It is important to cross-reference and use multiple sources to ensure accuracy and thoroughness.
A legal expert can help you interpret complex case law, apply it to your specific situation, and navigate the intricacies of legal research to ensure you have a comprehensive and accurate understanding of the law.
