A warrant or order that fails on its face to satisfy the particularity or identification requirements imposed by the Fourth Amendment or procedural rules. The defect appears in the document itself and cannot be cured by reference to an affidavit or other extrinsic materials.
Detective Ruiz obtained a warrant listing the correct clinic address but leaving the items-to-be-seized section entirely blank. Officers executed the warrant at the clinic without carrying the detailed affidavit. The clinic owner moves to suppress the seized records. The court grants the motion because the warrant is facially deficient and the affidavit cannot supply the missing particularity.
Agents obtained a warrant from a neutral magistrate after submitting an affidavit that omitted exculpatory emails. A later court finds the affidavit insufficient to establish probable cause. The company moves to suppress the seized files. The court denies suppression because the warrant was facially valid and the agents relied on it in objective good faith.

Agents obtained an arrest warrant identifying the suspect only by the online alias ZeroDay and a generic description of a male software engineer in the tech district. Multiple contractors matched the description. Agents arrested one contractor using the warrant. The arrestee moves to suppress evidence from the ensuing search. The court grants the motion because the warrant failed to identify the person with reasonable certainty on its face.
The exception does not apply when the warrant is so facially deficient that no reasonable officer could presume it valid. A warrant leaving the items-to-be-seized section blank or failing to identify the arrestee with reasonable certainty supplies an obvious example.

A bare-bones affidavit may still allow reasonable reliance if the warrant is facially valid. Facial deficiency, by contrast, appears on the warrant document itself and prevents any reasonable officer from believing the warrant authorizes the search or arrest.
Supporting sources
No. When multiple individuals match the alias and description, the warrant fails to identify the arrestee with reasonable certainty and is facially deficient. Post-issuance records cannot cure the defect on the face of the warrant.
