Texas DWI Defense Attorney Says Evidentiary Challenges Are Part of a Solid Defense Strategy


A solid DWI defense often includes multiple strategies for defeating the prosecution’s case against the defendant. Evidence is a critical component of the state’s case in any DWI case. When it’s possible that there could be a problem with one or more of the pieces of evidence that the state plans to present at trial, a defense attorney will often challenge the admissibility of the evidence in the hope that the court will agree with their argument and exclude the evidence from the trial. Since the state must be able to support its case against the defendant with the evidence it plans to present at trial, each piece of the state’s evidence that is excluded from the trial weakens the case against the defendant.

The Texas Court of Criminal Appeals recently issued a ruling that excludes the admission of a specific blood sample. In its ruling, the Court agreed with a lower court’s decision that the evidence was gathered in an unconstitutional manner, thus violating the defendant’s rights. The State tried, in its appeal, to persuade the Texas Court of Criminal Appeals that the judge who previously ruled in favor of excluding the evidence abused his judicial discretion. The Texas Court of Appeals has sent the case back to the 210th District Court for trial.

The defendant in the case mentioned above is a man from El Paso who is charged with the deaths of three people in connection with an automobile wreck that happened on Christmas Eve in 2014. Joel Garcia’s blood was taken without a warrant, in the hours following the crash. The State claimed that the blood sample had to be drawn before a warrant could be obtained because the defendant required immediate medical treatment after his accident. The defense argued that the defendant’s injuries did not require immediate medical treatment, rendering the warrantless  blood draw a violation of Garcia’s fourth amendment rights. After several appeals, the issue of whether the defendant’s blood sample is allowed as evidence in his trial was finally decided by the Texas Court of Criminal Appeals, as mentioned above.

Constitutional challenges are just one of the ways defense attorneys can attack the validity of blood samples and other types of physical evidence. In some cases, questions over the handling of items like blood samples lead to the exclusion of evidence that the state planned to rely on heavily in its case. Blood samples can be taken incorrectly, stored improperly, and in some cases even mixed up and mislabeled with the wrong name. Blood and breath testing equipment are not infallible, and challenges to the validity of test results are another way that defense counsel can sometimes have evidence excluded from a defendant’s trial.
