Incredibly, there is long-term opposition to Beate Merk's proposal. This article from almost two years ago.
Vorstoß aus Bayern: Missbrauch soll erst nach 30 Jahren verjähren - Nachrichten Politik - Deutschland - WELT ONLINE:
Strong criticism for the proposal came from the Opposition. "A society based on constitutional law is not only punitive but also a forgiving", the Alliance 90/The Greens spokesman in parliament on legal matters, Jerzy Montag told Welt Online. The current limitation periods are sufficient. Montag called the Merk proposals "absurd": "The policy is not based on Christianity but on fundamentalist rancour." (The German left has an entirely discreditable past to conceal on these matters, especially Cohn-Bendit, one of the Green's leaders and now an MEP)
Even in the CDU, Merk's proposal is controversial. "A blanket extension of the limitation period to 30 years is without purpose," said the legal affairs spokesman of the CDU / CSU faction in the Bundestag, Michael Grosse-Brömer to Welt Online. The decisive point is the severity of the offense. Grosse-Brömer argued for, in less serious cases, to raise the statute of limitations from five to ten years. Also, it would make sense to treat sexual abuse of children basically as a "crime" category, with a minimum sentence of one year in prison. So far, sexual abuse of children are classified as "misdemeanors" (Cathcon!!!)
Justice Minister received support from the Deutsche Kinderhilfe. "Especially with sexual offenses against children, the victims sometimes only talk about itecades later," said Chairman George Ehrmann to this newspaper. His association has therefore been calling for some time to extend the limitation period to 30 years.
