Rodriguez-Castellon v. Holder, 733 F.3d 847 (9th Cir. Oct. 22, 2013) (California conviction for lewd and lascivious acts upon a 15-year-old girl when the actor is at least ten years older, under Penal Code 288(c)(1), is a categorical crime of violence and therefore an aggravated felony, under INA 101(a)(43)(F), 8 U.S.C. 1101(a)(43)(F), because this offense, in the ordinary case, poses a substantial risk of the use of physical force under 18 U.S.C. 16(b)).

Note: Although not a positive case, the discussion does carefully address prior Ninth Circuit case law and has some very useful analysis distinguishing 18 U.S.C. 16(b), substantial risk analysis from the minimum-conduct analysis required for other portions of the Act, including Sexual Abuse of a Minor, Child Abuse, Domestic Violence, and 18 U.S.C. 16(a).
