United States v. Young, ___ F.3d ___ (9th Cir. Aug. 17, 2006) (18 U.S.C. 922(g)(8)(A) makes it a federal offense to possess a firearm by one against whom a domestic violence restraining order has been issued "after a hearing of which such person received actual notice, and at which such person had an opportunity to participate" and there is no right to collaterally attack the constitutionality of the state court restraining order since those proceedings are immaterial except to the extent that the federal statute explicitly requires certain procedural protections).
