Pearson v. Winston

Issue: (1) Whether the Fourth Circuit created an impermissible end-run around Harrington v. Richter, Cullen v.

Washington in concluding as a de novo matter, and contrary to the Virginia Supreme Court and Strickland, that trial counsel were ineffective for deciding not to argue mental retardation at sentencing?
