Gradiz v. Gonzales, 490 F.3d 1206, ___, (10th Cir. Jun. 20, 2007) ("[T]he First Offender Act, 18 U.S.C. 3607, permits the expungement of first-time simple drug-possession offenses for all purposes, including immigration adjudications. As the Ninth Circuit noted in Lujan-Armendariz, there is no reason to suppose that Congress repealed the First Offender Act sub silentio. It thus makes sense to read the 1101(a)(48)(a) definition to exclude expungements.").
