What are the search warrant requirements in New York?
New York's warrant law is set out in Article 690 of the Criminal Procedure Law, and the state constitution frequently outpaces federal doctrine in protecting privacy.
1. Constitutional Foundation
The Fourth Amendment is supplemented by N.Y. Const. art. I § 12, which the Court of Appeals has interpreted to provide greater protection in many contexts (People v. P.J. Video; People v. Scott — privacy in posted lands).
2. Probable Cause & Affidavit
CPL § 690.35 requires a sworn written application by a public servant. The affidavit must particularly describe the place and items (§ 690.45). New York applies the Aguilar-Spinelli two-pronged test for informant tips under its constitution, rejecting the more permissive federal Gates totality-of-the-circumstances test (People v. Griminger). Anticipatory warrants are valid with a defined triggering event.
3. Who Issues
CPL § 690.05 authorizes any local criminal court judge — including Supreme Court justices, County Court judges, District Court judges, City Court judges, and Town/Village Justices — to issue a warrant within their geographic jurisdiction.
4. Execution
CPL § 690.50 codifies knock-and-announce: officers must give notice of authority and purpose and may force entry only after refusal. No-knock authorization requires a showing under § 690.35(4)(b) that property may be destroyed or officers endangered. Execution must occur within 10 days (§ 690.30), and nighttime (9 p.m.-6 a.m.) service requires a specific judicial endorsement.
5. Scope & Plain View
Search is limited to areas where listed items could reasonably be hidden. Plain-view seizure is allowed when officers are lawfully present and incriminating nature is immediately apparent (Horton v. California).
6. Exceptions to the Warrant Requirement
Consent, search incident to arrest, exigent circumstances, automobile (more limited than federal — People v. Galak), inventory, protective sweep, and Terry frisk.
7. Suppression
New York applies a robust exclusionary rule and has REJECTED the Leon good-faith exception under its state constitution (People v. Bigelow).
