John Demjanjuk will appeal his conviction and death sentence for Nazi war crimes by next month, and Israel's Supreme Court will hear the case beginning Dec. 5, a court spokesman said Monday.

The spokesman, Shmaryahu Cohen, said in a telephone interview that the Ukrainian-born Demjanjuk, 68, has a June 10 deadline to file the appeal but that the retired Ohio autoworker's lawyers could request an extension.The appeal will be heard by five justices for three consecutive days, and then for another three days between Dec. 12 and 15, Cohen said, adding that Israeli prosecutors are scheduled to reply from Dec. 19 to Dec. 29.

The court will convene at the Supreme Court building in Jerusalem and provide simultaneous translations of the Hebrew language proceedings into English and Ukrainian, Cohen said.
