Kastner emigrated to Israel in 1947. He was a spokesman for the Minister of Trade and Industry when his negotiations with Eichmann became the subject of controversy. Kastner had been told in April or May 1944 of the mass murder that was taking place inside Auschwitz. Allegations spread after the war that he had done nothing to warn the wider community, but had focused instead on trying to save a smaller number. The inclusion on the train of his family, as well as 388 people from the ghetto in his home town of Kolozsvár, reinforced the view of his critics that his actions had been self-serving.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".
