Possession denotes actual rule over an object, i.e. the ability of possessor to actually dispose of the object he holds in possession. It should be distinguished from the right of ownership because those two concepts not only differ, but the right of ownership partly encompasses the possession. As well as all other rights, the right of possession can be disturbed by third parties. Disturbing can be in the form of disturbing the possessor in the act of possessing or depriving him of possession against his will. Possessor can defend himself by allowed self-assistance and judicial protection of the possession. Allowed self-assistance denotes the right of the possessor to reject the autocratic disturbance of the possession by appropriate force against anybody who autocratically disturbs him in possession or has taken it away from him. Judicial protection of possession is realized by raising possession suits before the municipal court, which on those requests decides in an emergent procedure. In conducted possession suits, the prosecutor has to prove that he is the last peaceful possessor. In such cases, the courts decide by a decree and not a ruling. In case the possessor, who is at the same time the owner, does not manage to protect his right by possession suit in the emergency procedure, he still has ownership suits on which the court decides in a regular procedure. Therefore the procedure is longer-lasting and also much more expensive and complicated. It does not provide the emergency protection which the possessor-owner needs because during whole of the procedure he has to tolerate disturbing but after a successfully completed procedure, it brings legal security.
