The judiciary of Germany is the system of courts that interprets and applies the law in Germany.
The German legal system is a civil law mostly based on a comprehensive compendium of statutes, as compared to the common law systems. In criminal and administrative law, Germany uses an inquisitorial system where the judges are actively involved in investigating the facts of the case, as compared to an adversarial system where the role of the judge is primarily that of an impartial referee between the prosecutor or plaintiff and the defendant or defense counsel.
In Germany, the independence of the judiciary is historically older than democracy. The organisation of courts is traditionally strong, and almost all federal and state actions are subject to judicial review.
Judges follow a distinct career path. At the end of their legal education at university, all law students must pass a state examination before they can continue on to an apprenticeship that provides them with broad training in the legal profession over two years. They then must pass a second state examination that qualifies them to practice law. At that point, the individual can choose either to be a lawyer or to enter the judiciary. Judicial candidates start working at courts immediately. However, they are subjected to a probationary period of up to five years before being appointed as judges for life.
The judicial system is established and governed by part IX of the Basic Law for the Federal Republic of Germany. Article 92 of the Basic Law establishes the courts, and states that "the judicial power shall be vested in the judges; it shall be exercised by the Federal Constitutional Court, by the federal courts provided for in this Basic Law, and by the courts of the Länder."
Law
Germany's legal system is a civilian system whose highest source of law is the 1949 Basic Law for the Federal Republic of Germany (which serves as the nation's constitution), which sets up the modern judiciary, but the law adjudicated in court comes from the German Codes; thus, German law is primarily codal in nature. The court system adjudicates (1) public law (), that is, administrative law (civil-government litigation or litigation between two government bodies) and criminal law, and (2) private law (). German law—especially private law—is mainly based on early Byzantine law, specifically Justinian's Code, and to a much lesser extent the Napoleonic Code.
German law is not impregnated with legal positivism to the extent of Napoleonic legal systems, so Germany's judiciary is not subordinated to the legislature; the Basic Law directly invests supreme judicial power in the Constitutional Court as well as other federal courts and the courts of each Länder, and case law has greater importance, though not to the extent of common law systems.
In contrast to the adversarial system used by common law countries, the German system of criminal (and administrative) procedure is inquisitorial. Rather than allowing cross-examination between the defense and prosecutors, the judges conduct the majority of the trial. During a trial, the parties are expected to give all their evidence to the judges, who will then call forward and question the witnesses, after which the defense counsel and prosecutor may question the witnesses.
Courts
The primary legislation concerning court organization is the Courts Constitution Act (, or ). The courts are characterized by being specialist, regional, and hierarchically integrated at the federal level. There are five basic types of courts, plus the Federal Constitutional Court and the Länder's constitutional courts:
Ordinary courts, dealing with criminal and most civil cases
Administrative law courts
Tax law courts
Labour law courts
Social law courts
Constitutional law courts, focusing on judicial review and constitutional interpretation
The main difference between the Federal Constitutional Court and the Federal Court is that the Federal Constitutional Court may only be called if a constitutional matter within a case is in question (e.g., a possible violation of human rights in a criminal trial), while the Federal Court of Justice may be called in any case. Only the Constitutional Court can declare an Act of Parliament invalid.
