Kamagate v. Ashcroft, 385 F.3d 144 (2d Cir. Sept. 21, 2004) (removal of respondent did not render moot a federal habeas action under 28 U.S.C. 2241 challenging validity of removal order on basis of aggravated felony, since he can show some 'collateral consequence' ... meaning 'some concrete and continuing injury other than the now-ended [threat of removal]' to establish a live case or controversy; noncitizen convicted of a crime of moral turpitude may seek cancellation of removal and thereby avoid permanent inadmissibility, only if he is not an aggravated felon; fact that noncitizen removed as aggravated felon causes ongoing damage sufficient to create case and controversy).
