Brief filed: 06/29/2021


Hemphill v. State of New York

United States Supreme Court; Case No. 20-637

Prior Decision

Decision below 35 N.Y.3d 1035 (N.Y. June 25, 2020)


When a defendant opens the door to responsive evidence, he does not also forfeit his right to exclude evidence otherwise barred by the Confrontation Clause. The New York rule chills vital defense arguments. The New York rule forces defendants into a Hobson’s choice between constitutional rights. The New York rule undermines the institution of the criminal trial.
