Garcia v. Ashcroft, 394 F.3d 487 (7th Cir. Jan. 6, 2005) (jurisdiction limitation triggered by state controlled substances conviction precludes consideration of claim state possession conviction did not constitute aggravated felony; petition for review transferred to district court as habeas corpus petition to determine whether state felony conviction for possession of a controlled substance, which would have been punishable only as a misdemeanor under federal law, qualifies as an aggravated felony).
