The allegations culminated in Kastner being accused in a newsletter of having been a Nazi collaborator. The government sued for libel on his behalf, and the defendant's lawyer turned the trial into an indictment of the Mapai (Labour) leadership and its alleged failure to help Europe's Jews. The judge found against the government, ruling that Kastner had "sold his soul to the devil" by negotiating with Eichmann and selecting some Jews to be saved, while failing to alert others. Kastner was assassinated in Tel Aviv in March 1957. Nine months later, the Supreme Court of Israel overturned most of the lower court's ruling, stating in a 4–1 decision that the judge had "erred seriously".
