A federal appeals court has refused to rehear the deportation case of a retired western Pennsylvania steelworker who served as a Nazi concentration camp guard during World War II. The only recourse now for Anton Geiser, a naturalized US citizen, is to appeal to the US Supreme Court. The 3rd US Circuit Court of Appeals in Philadelphia ruled in June that Geiser, 83, should have his citizenship revoked and be deported because his work as a guard meets the type of persecutory conduct banned under the Refugee Relief Act, which was in effect when he entered the US His attorneys had wanted the three-judge appellate panel or the entire 3rd Circuit to rehear the case. The appeals court refused last week. Geiser's attorney, Adrian Roe, declined to comment Thursday.
