The Ninth Circuit has rejected a void-for-vagueness challenge to the phrase "crime involving moral turpitude."  The Court deemed itself bound by the Supreme Court's decision in Jordan v. DeGeorge, though it recognized that "later Supreme Court cases cast some doubt on its general reasoning."  The Court rejected the Government's argument that the void-for-vagueness doctrine cannot apply to any ground of inadmissibility.
