State of Texas v. Christi Lynn Johnston, Appellee

Summary

The Court of Criminal Appeals of Texas reversed the Court of Appeals and held that the warrant‑based blood draw performed by a police officer in a police‑department blood‑draw room was reasonable under the Fourth Amendment, that the Texas Transportation Code does not control the Fourth Amendment analysis, and that the officers' failure to obtain a medical history or record the draw did not make the draw unreasonable. The decision was joined by a concurring opinion warning against extending the holding to roadside draws.
