The two highest courts, the Supreme Court (Högsta domstolen) and the Supreme Administrative Court (Högsta förvaltningsdomstolen), have the right to set precedent which is in practice (however not formally) binding on all future application of the law. Courts of appeal, both general courts (hovrätter) and administrative courts (kammarrätter), may also issue decisions that act as guides for the application of the law, but these decisions may be overturned by higher courts. Much of the case law is used to prove the existence of a law and not, unlike many common law jurisdictions, the creation of law.
