On May 7, 2009, the US Supreme Court denied an application for a stay of deportation filed by accused concentration camp prison guard John Demjanjuk. Demjanjuk was facing deportation to Germany where he had been charged with 29,000 counts of accessory to murder for his alleged actions at the Sobibor concentration camp. Demjanjuk fought a lengthy legal battle against such allegations that included a denial of certiorari by the US Supreme Court in Demjanjuk v. Mukasey. He had previously been convicted and sentenced to death by an Israeli court in 1988 after being mistakenly identified as a former guard at Treblinka. That conviction was ultimately overturned by the Israeli Supreme Court in 1993. Following the Supreme Court's ruling, Demjanjuk was deported to Germany and convicted of assisting in the Holocaust by the Munich Regional Court in May 2011. However, he died in March 2012 at the age of 91 before the German Appellate Court issued the final verdict in his case.
