Cornell Law professor Sherry F. Colb comments on the U.S. Supreme Court’s decision in Edwards v. Vannoy, in which it held that a prisoner may not invoke the denial of his Sixth Amendment right to a unanimous jury as a basis for challenging his criminal conviction when filing a federal habeas corpus petition. Professor Colb explains why, if cost/benefit analysis played a role in determining retroactivity, the Court perhaps should have decided that case the other way.
