Habeas – Violation of State Law not Supported
Wilson v. Corcoran, USSC No. 10-91, 11/8/10, vacating and remanding habeas grant in, Corcoran v. Levenhagen, 593 F.3d 547 (7th Cir. 2010)
Mere violation of state law doesn’t support habeas relief, violation of federal law being required.
But it is only noncompliance with federal law that renders a State’s criminal judgment susceptible to collateral attack in the federal courts.
