What is the current state of the law on habeas corpus under the Anti-Deficiency Amendments Amendments to be brought before the Federal Court of Appeal?

But while setting a high standard for relief, AEDPA protects and preserves the critical role federal courts play in identifying and correcting constitutional errors. Even under the strict dictates of AEDPA, constitutional infirmity in a state court conviction does not become immunized against federal review by virtue of subsequent affirmances in the state courts of appeals. See Slack v. McDaniel , 529 U.S. 473, 483, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000) ("The writ of habeas corpus plays a vital role in protecting constitutional rights.").
