What are the search warrant requirements in Washington?
Washington's warrant procedure is set out in Superior Court Criminal Rule 2.3 and Chapter 10.79 RCW, with state constitutional protection under art. I § 7 that is notably broader than the Fourth Amendment.
1. Constitutional Foundation
Wash. Const. art. I § 7 — "No person shall be disturbed in his private affairs, or his home invaded, without authority of law" — provides BROADER protection than the Fourth Amendment (State v. Gunwall). It protects more privacy interests and is enforced through an independent state exclusionary rule.
2. Probable Cause & Affidavit
CrR 2.3(c) requires a sworn affidavit (or recorded sworn testimony) stating facts establishing probable cause. The warrant must particularly describe the place and items. Washington applies the Aguilar-Spinelli test for informant tips under art. I § 7, rejecting the federal Gates test (State v. Jackson). Anticipatory warrants are recognized.
3. Who Issues
CrR 2.3(b) authorizes a "court" — a superior, district, or municipal court judge — to issue warrants within the relevant jurisdiction. The issuer must be neutral and detached.
4. Execution
RCW 10.31.040 codifies knock-and-announce: officers may break open doors only after notice of authority and purpose and refusal. No-knock authorization requires a strong showing of danger or destruction (State v. Coyle). CrR 2.3(c) requires execution within 10 days. The Washington Supreme Court has held that violations of the knock-and-announce rule still warrant suppression under art. I § 7, departing from Hudson v. Michigan (State v. Schultz).
5. Scope & Plain View
Search is limited to areas where listed items could reasonably be hidden. Plain-view seizure is permitted when officers are lawfully present and incriminating nature is immediately apparent.
6. Exceptions to the Warrant Requirement
Washington's "private affairs" doctrine narrows several federal exceptions — automobile searches under art. I § 7 are more restricted (State v. Snapp), consent must be voluntary and free of coercion, and inventory searches require strict adherence to written policy.
7. Suppression
Washington REJECTS the Leon good-faith exception under art. I § 7 (State v. Afana). Evidence obtained in violation is excluded.
