Public law (Öffentliches Recht) rules the relations between a citizen or private person and an official entity or between two official entities. E.g., a law which determines taxes is always part of the public law, just like the relations between a public authority of the Federation (
Bund) and a public authority of a state (
Land). Public law was formerly based on the so-called "Über-Unterordnungs-Verhältnis" ("superiority inferiority relationship"). That means that a public authority may define what is to be done, without the consent of the citizen. (E.g., if the authority orders a citizen to pay taxes, the citizen has to pay, even without an agreement.) In return, the authority has to abide by the law and may only order if empowered by a law. The newer and now most acknowledged theory to determine whether a regulation is public or civil law is the "modifizierte Subjektstheorie" (modified theory of subjects). A codified regulation is public law, if at least one of the subjects is part of the state ("Der Staat" as is meant legislative, executive and judiciary) or is legally empowered to act on behalf of any part of the state. This Theory was necessary, because the Theory of "Über-Unterordnungs-Verhältnis" failed in certain situations, e.g.: A parent is legally superior to a minor. The minor cannot sign any contract without a parent's consent. Following the old theory, this would be a case of "Überordnung", which would qualify these regulations as public law. The newer theory qualifies these regulations as private law, because though the parents are superior, they are not part of the state nor acting on behalf of any. A subject in the sense of the
Modifizierte Subjektstheorie is the addressee, that might be entitled or obligated to do or to forbear something; e.g.: Tax Laws entitle the state to collect taxes, criminal law entitles the state to imprison criminals and also obligates the state to resolve crimes.
Constitutional law The constitution (Verfassung) is called the Grundgesetz (Basic Law) because the drafters saw this legal "corpus" as a provisional document, to be replaced by the constitution of a future united Germany. In reaction to National Socialism, the Grundgesetz shows mistrust towards its own people and its own government and was created as a reaction to the problems of the Weimar Constitution. Where the Weimar Constitution was weak, this constitution, the Basic Law was strong, where the Weimar Constitution left every decision to the free will of the legislator, the basic law defines the boundaries that nobody is allowed to cross. Wherever possible, powers are limited and controlled. The constitutional law
(Verfassungsrecht) deals, of course, mostly with Germany's constitution and the rights and duties of the various institutions. A major part are the
Civil rights which are first in the basic law
(Grundgesetz) and from which everything else derives. As usual in western democracies, the three powers are separated: the executive is taken care of by the government, the judicative by the courts and judges, and the legislative is managed by the federal and state parliaments. The most important principles, apart from that, are
Democracy,
Federalism and
Rechtsstaatsprinzip, meaning that the whole of the state must be based on laws. These parts of the Grundgesetz are forbidden to be changed. Decisions may be made according to the definition of these regulations, but the essential content has to be unaffected. The highest authority in constitutional law, and to some extent in German law as a whole, is the Federal Constitutional Court (
Bundesverfassungsgericht). The Bundesverfassungsgericht is no Supreme Court. It is not a court of last instance. Its only purpose is the protection of the constitution, by control of the actions of government, judicative and legislative according to constitutional procedures and the ensuring of constitutional rights and duties. Here, the various parts of the state can dispute about the extent of their authority, but it is also the place to appeal to when a citizen feels that he is being deprived of his civil rights. This particular matter takes up a lot of the court's work and often reshapes the legal process itself if the court finds that a certain law does in fact interfere with civil rights. Decisions of other courts are varied only with regard to violations of the constitution. Other mistakes are not relevant. Again, European law has a certain influence here as the Grundgesetz is no longer the sole source of law, instead it is joined by the treaties and laws of the European Union. Apart from the constitution of the Federal Republic, each state ("Land") has its own constitution (e.g. see
Constitution of Hamburg) and, necessarily, its own constitutional law and court. Nonetheless the Grundgesetz and the Bundesverfassungsgericht are appropriate to actions of the states (
Länder) and their branches.
Administrative law The administrative law is the law of the
Executive. It covers most kinds of legal relations between the state and the citizens, but also between different bodies and/or levels of government with the exception of constitutional law, but not those legal relations, when the state closes contracts like any other private citizen. The highest administrative court for most matters is the
Bundesverwaltungsgericht (Federal Administrative Court). There are federal courts with special jurisdiction in the fields of social security law (
Bundessozialgericht) and
tax law (
Bundesfinanzhof).
Administrative civil law The executive may act on grounds of the "Bürgerliches Gesetzbuch" (BGB, "civil code"). However, if a governmental office acts on ground of the "BGB" (e. g.: is buying a pencil), this office is bound to the "Grundgesetz" (and other laws) to prevent unequal treatment of citizens and businesses.
Criminal law Criminal law is a matter of federal law in Germany. The main source of law here is the
German Penal Code promulgated in 1871. Minors under 14 years old cannot be held liable for crimes in court; however, for minors between 14-18 years of age and in case of missing maturity under the age of 21, there are special juvenile courts and some adjustments to the criminal law as well. In court, a public prosecutor (
Staatsanwalt) carries out prosecutions, and the defendant can (in many cases has to) choose a defence attorney to defend him. The office of the public prosecutor
(Staatsanwaltschaft), together with the police forces, handle the investigations in the case at hand, yet they are not party to the case. The judgement is handed down by a single judge or in higher courts a bench of judges, of which two are lay magistrates (
Schöffen) in certain cases. In the criminal system, judges and magistrates are the only triers of fact and law; German law does not recognize
trial by jury. Sentences run the gamut from fines to
life imprisonment, which is usually open to appeal after 15 or more years for constitutional reasons. The
death penalty is explicitly forbidden by the constitution. Extremely dangerous persons can be turned over for psychiatric treatment or have to stay in prison as long as necessary—which can mean for the rest of their lives
(Sicherungsverwahrung)—in addition to their punishment. == Private law ==
