In the case of the
Red Army Faction terrorist
Christian Klar, the parole court ordered a deferment of at least 11 years (making his sentence a minimum of 26 years) before he again became eligible for parole. Such a long length was due to his involvement in multiple killings, lack of remorse, and his affiliation with a
terrorist group. In another case, a court ruled the defendant had to serve at least 38 years in
prison for the murder of five people. He was incarcerated beyond the required 38 years after it was determined he was a danger to society. Such a ruling mandates continued imprisonment
de jure, as being safe toward society is required to be paroled from a life sentence (§ 57a I Nr. 3 StGB in conjunction with § 57 I Nr. 2 StGB). However, the case was
appealed to the
German Constitutional Court (BVerfG, Judgment from 29.11.2011 - 2 BvR 1758/10), which
held that the decision to hold the prisoner beyond the original 38 years was unconstitutional for case-specific reasons. One of the most prominent "long termers" has been
Heinrich Pommerenke, who in total had served 49 years, from 1959 until his death in 2008, for
mass murder and
rape. As of 2023, the record is held by
Hans-Georg Neumann who was sentenced to life in prison in 1963 for murdering a pair of lovers and completed 59 years (including
pretrial detention) in prison until his release was ordered in 2021. ==Release and imposition of preventive detention==
