Texas Criminal Defense Group releases guide on challenging DWI blood test evidence, particularly referencing samples drawn without consent. The resource addresses Fourth Amendment protections and defense strategies for Texas drivers facing blood-test-based prosecutions.
-- Texas Criminal Defense Group has released a guide addressing how individuals facing DWI charges can challenge blood test evidence in court, particularly when samples were drawn without proper consent. The resource is intended for Texas drivers confronting prosecutions built on blood test results, detailing the specific Fourth Amendment protections that typically require police to obtain either consent or a warrant before conducting blood draws.

Blood tests have become central to DWI prosecutions across Texas because they offer advantages that breath tests cannot match. Unlike breathalyzers, which measure only alcohol and face accuracy challenges, blood samples detect both alcohol and drugs while providing precise Blood Alcohol Concentration levels that courts consider highly reliable. However, this investigative preference often leads to Fourth Amendment violations, as blood draws are invasive searches that require strict adherence to voluntary consent or judicial authorization. Prosecutors build cases around blood evidence that can be difficult to refute without understanding the legal framework governing its collection.
They may introduce refusal as evidence suggesting consciousness of guilt, and these consequences pressure many drivers into compliance, making challenges to the legality of the blood draw itself a critical defense avenue when consent was not truly voluntary or when procedural violations occurred.
The Texas Criminal Defense Group guide highlights the importance of blood draws, noting that "a conviction for DWI can also carry a fine ranging from $2,000 to $10,000, as well as a license suspension of between 90 days and two years, depending upon the severity of the case."
The firm explains that a blood draw is not an infallible "smoking gun" but a complex forensic process prone to human and mechanical error. Its approach centers on aggressive discovery, forcing the state to prove the scientific integrity of the sample from the needle to the lab.
Defense strategies for challenging blood test admissibility operate on multiple levels, targeting both the collection process and the handling of samples. Attorneys examine whether warrants were properly obtained and whether claimed exigent circumstances genuinely existed, since Fourth Amendment violations can lead to evidence suppression. Procedural errors during collection—such as blood drawn by unqualified personnel or improper technique—undermine reliability, while chain of custody problems, including contamination, mishandling, or sample mix-ups, create additional grounds for exclusion.
Texas Criminal Defense Group utilizes the services of in-house forensic toxicologists to scrutinize blood test evidence in DWI cases, scrutinizing laboratory procedures and identifying weaknesses that even strong BAC results cannot overcome when the evidence was obtained unlawfully.
The firm brings 27 years of criminal defense experience to DWI cases, led by Attorney Stephen Hamilton, with an approach centered on thorough evidence analysis and constitutional protection.
With a flat-fee structure that covers all stages of the case, including trial representation, and a willingness to challenge every aspect of the prosecution's case, Texas Criminal Defense Group provides Texans with resources to fight back against potentially unlawful blood draws and protect their constitutional rights.
