Martinez v. Ryan, 566 U.S. 1 (2012), was a United States Supreme Court case which considered whether criminal defendants ever have a right to the effective assistance of counsel in collateral state post-conviction proceedings. The Court held that a procedural default will not bar a federal habeas court from hearing ineffective-assistance-of-trial-counsel if there was no counsel or ineffective counsel in an initial-review collateral proceeding.
