Functions of the judiciary in different law systems

In common law jurisdictions, courts interpret law; this includes constitutions, statutes, and regulations. They also make law (but in a limited sense, limited to the facts of particular cases) based upon prior case law in areas where the legislature has not made law. For instance, the tort of negligence is not derived from statute law in most common law jurisdictions. The term common law refers to this kind of law. Common law decisions set precedent for all courts to follow. This is sometimes called stare decisis.
