In 1968, the "Bundestag" passed a Misdemeanors Bill dealing with traffic misdemeanors, into which a high-ranking civil servant named Dr. Eduard Dreher who had been drafting the bill inserted a prefatory section to the bill under a very misleading heading that declared that henceforth there was a statute of limitations of 15 years from the time of the offense for the crime of being an accomplices to murder which was to apply retroactively, which made it impossible to prosecute war criminals even for being accomplices to murder since the statute of limitations as now defined for the last of the suspects had expired by 1960. The "Bundestag" passed the Misdemeanors Bill without bothering to read the bill in its entirety so its members missed Dreher's amendment. It was estimated in 1969 that thanks to Dreher's amendment to the Misdemeanors Bill that 90% of all Nazi war criminals now enjoyed total immunity from prosecution. The prosecutor Adalbert Rückerl who headed the Central Bureau for the Prosecution of National Socialist Crimes told an interviewer in 1969 that this amendment had done immense harm to the ability of the Bureau to prosecute those suspected of war crimes and crimes against humanity.
