the State of Texas v. Bhavesh G. Patel, 05-20-00129-CR

Background

Early-morning traffic stop after officer observed traffic violations; officer smelled alcohol, observed red eyes, and Patel admitted drinking; Patel failed field sobriety tests and was arrested.
Patel refused a voluntary blood draw; officer obtained a magistrate-issued search warrant authorizing seizure of Patel’s blood (warrant specified a six-hour execution window).
Blood was drawn shortly after issuance and submitted to SWIFS; the lab tested the sample four days later and reported a BAC of 0.201 g/100 ml.
Patel moved to suppress the blood-analysis results, arguing (relying on State v. Martinez) that chemical analysis is a separate Fourth Amendment search requiring a separate warrant and that the warrant was an impermissible general warrant.
The trial court granted suppression, but on grounds not asserted by Patel at the hearing: (1) the officer failed to file a timely return and inventory under Tex. Code Crim. Proc. art. 18.10, and (2) the BAC analysis was performed outside the statutory execution period; the court did not base its ruling on Patel’s separate-warrant argument.
The State appealed; the court of appeals reversed the suppression order and remanded for further proceedings.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Patel)	Held
1) Trial court relied on unraised grounds	Trial court erred to suppress on grounds not pled or litigated	Court improperly suppressed based on execution/return defects (Patel conceded he did not contest the draw)	Reversed: suppression cannot stand where ruling rests on issues not raised at hearing; State lacked notice and opportunity to develop record
2) Failure to file warrant return/inventory	Article 18.10's failure-to-return does not bar admission; no prejudice shown	Lack of return/inventory invalidates warrant and requires suppression	Reversed: art. 18.10 expressly does not bar admission; failure to return is a technical defect that does not vitiate warrant absent prejudice
3) Timeliness of testing under warrant execution period	Execution occurs when blood is drawn; statutory deadlines govern seizure, not later lab analysis	Analysis outside the warrant’s execution window renders testing unlawful	Reversed: warrant was executed when blood drawn (within six hours); testing later does not violate art. 18.07
4) Whether a separate warrant was required for chemical analysis	No separate warrant required; magistrate’s probable-cause finding to seize for forensic purposes suffices to authorize testing	Martinez requires a separate warrant / analysis is a distinct search; warrant was a general warrant if it didn’t specify testing	Reversed: following Crider, Jones, Staton, forensic testing of blood seized under a valid warrant does not require a second warrant
