The statutory limitation as a legal institution of criminal law has been well discussed and frequently modified during the last couple of years. The political debates that preceded these modifications tended to be rather emotional and mostly (especially when it was about the very sensitive topic of sexual offenses) led to an aggravation of the current legal status. The most important instruments to regulate the law of statutory limitation are the actual periods of limitation that are laid down in § 57 StGB and depend on the range of punishment for the crime. These periods of limitation are completed by the facts of extension in § 58 StGB, that can prevent the statutory limitation or at least hinder the periods of limitation to run out under certain circumstances. At first, this thesis shall give an overview on the current legal situation of the criminal statutory limitation of § 57 StGB; then each of the facts of extension of § 58 StGB will be deeply analyzed and discussed. Doing so, this thesis is not only going to give pure legal explanations but will also discuss the ratio legis, the opinions in literature (party from a psychological point of view) and jurisdiction as well as the dogmatic background of the rules for statutory limitation. One main emphasis shall be put on the 2. Gewaltschutzgesetz 2009, which seems to be of particular interest because of the recent and important changes that were involved with it. Also, some other selected problems that are connected with the facts of extension, such as the retroactive effects of a new legal situation of the criminal statutory limitation on crimes that were already committed or the psychological ratio legis of the obstruction of periods of limitation regarding sexual offenses, will be discussed,.
