Harry Blackmun,
Coleman v. Thompson — Dissenting Opinion
“ To permit a procedural default caused by attorney error egregious enough to constitute ineffective assistance of counsel to preclude federal habeas review of a state prisoner's federal claims in no way serves the State's interest in preserving the integrity of its rules and proceedings. The interest in finality, standing alone, cannot provide a sufficient reason for a federal habeas court to compromise its protection of constitutional rights. ”
