Nonstatutory law is law that is not created by statute, but rather by court decisions. There are several synonyms for nonstatutory law, including case law, common law, judge-made law, and precedent. Case law refers to legal decisions that have been made by courts, and are often used as a basis for future legal decisions. Common law refers to the body of law that has been developed over time through judges' decisions and legal custom. Judge-made law refers to legal decisions that have been made by judges, either in the common law tradition or in the context of constitutional law. Precedent refers to legal decisions that provide a basis for future legal decisions. Ultimately, all of these terms refer to the same thing: nonstatutory law that is developed through the courts.
