State of Texas v. Christi Lynn Johnston, Appellee

Summary

The Texas Court of Criminal Appeals reversed the Court of Appeals, holding that the compelled blood draw of Christi Lynn Johnston by police officers in a police‑station blood‑draw room was reasonable under the Fourth Amendment and that the trial judge's suppression order was erroneous; the court also concluded that the Texas Transportation Code is not controlling for Fourth Amendment reasonableness analysis. Justice Johnson, in a concurring opinion, warned that blood draws performed outside a medical environment, such as roadside draws, may violate the Fourth Amendment.
