The Constitution protects against unreasonable searches, so a search warrant must meet strict requirements to be valid: it must be issued upon probable cause, personally determined by a judge, after examination under oath of the complainant and the witnesses they may produce, and it must particularly describe the place to be searched and the things to be seized. A warrant that fails to particularly describe these — a general warrant — is void. A search warrant is generally implemented in the daytime, and the search of a house should be in the presence of the lawful occupant or two witnesses. Evidence seized under an invalid warrant, or in an unreasonable search, is inadmissible. There are recognized exceptions where a search without a warrant is valid, such as a search incident to a lawful arrest, seizure of items in plain view, a consented search, a stop-and-frisk under genuine suspicion, a search of a moving vehicle, and customs searches. These exceptions are strictly construed.
Your home and belongings are protected against unreasonable searches. A search warrant is valid only if it meets strict constitutional requirements.
The Requirements for a Valid Warrant
A search warrant must be:
- Issued upon probable cause;
- Personally determined by a judge (not delegated);
- After examination under oath of the complainant and the witnesses they produce; and
- Particularly describing the place to be searched and the things to be seized.
No General Warrants
The particularity requirement is crucial. A warrant that does not specifically describe the place and items — a general warrant or a “scatter-shot” warrant covering multiple unrelated offenses — is void. This prevents officers from conducting fishing expeditions.
How It Must Be Implemented
- Generally served in the daytime, unless the warrant authorizes night service on a proper showing;
- The search of a house should be in the presence of the lawful occupant or, in their absence, two witnesses of the locality; and
- Officers may seize only the items described (plus items in plain view that are themselves contraband/evidence).
Invalid Warrant = Inadmissible Evidence
Evidence obtained under an invalid warrant, or through an unreasonable search, is inadmissible for any purpose in any proceeding — the exclusionary rule.
Valid Warrantless Searches (Exceptions)
Certain searches are valid without a warrant, but these are strictly construed:
- Search incident to a lawful arrest — of the person and immediate area, after a valid arrest;
- Plain view — seizure of items in plain view of an officer who is lawfully present, when the incriminating nature is immediately apparent;
- Consented search — where consent is voluntary, made by one with authority;
- Stop-and-frisk — a limited pat-down based on genuine, reasonable suspicion;
- Search of a moving vehicle — where obtaining a warrant is impracticable and there is probable cause; and
- Customs searches and searches at borders/checkpoints under their rules.
Practical Takeaways
- A valid search warrant needs probable cause, a judge's personal determination, examination under oath, and particular description of place and things;
- General warrants are void, and evidence from an invalid search is inadmissible;
- Warrantless searches are valid only under strict exceptions (incident to arrest, plain view, consent, stop-and-frisk, moving vehicle, customs).

What is a general warrant? A warrant that fails to particularly describe the place and items to be seized, or covers multiple unrelated offenses. A general warrant is void because it enables fishing expeditions.
