Whether Mateo's death sentence had to be vacated because he went to trial while New York's unconstitutional plea provisions were operative.
Holding
Yes. The death sentence had to be set aside because the Appellate Division's ruling upholding the plea provisions was binding in the Fourth Department when Mateo went to trial.
Reasoning
Matter of Hynes v. Tomei held that New York's plea provisions created an unconstitutional two-tiered punishment scheme. Under that scheme, a defendant who waived trial and pleaded guilty could not receive death, while a defendant who exercised the rights to a jury trial faced that possibility. People v. Harris had already required vacatur of a death sentence imposed under that system.
Although the County Court initially ruled the plea provisions unconstitutional in Mateo's case, the Appellate Division later declared them constitutional in an action involving this defendant and trial judge. That Appellate Division decision was binding precedent in the Fourth Department when jury selection and trial occurred.
The Appellate Division ruling meant that Mateo could realistically avoid a death sentence only by waiving a jury trial and pleading guilty. That burden on his Fifth and Sixth Amendment rights was precisely the constitutional defect identified in Jackson and Hynes. The timing of the trial—after the Appellate Division's decision but before the Court of Appeals invalidated the provisions—did not cure the defect.
