The People of the State of New York v. Merle Eugene McCartney

Summary

The Court affirmed the Appellate Division’s denial of a certificate under CPL 640.10 to compel an out‑of‑state Maryland trooper, holding that the trial judge properly exercised discretion because the defendant failed to show the witness’s materiality, and reiterating that the Sixth Amendment does not constitutionally require a state to secure out‑of‑state witnesses.
