Houston and Austin, Texas, DWI/DUI Defense Lawyers
When fighting charges of drunk driving, experience and legal knowledge can tip the scale. With offices in Houston and Austin, the attorneys Ralph Manginello and John Butler of The Manginello Law Firm, PLLC have handled hundreds of DUI/DWI cases.
Before you plead guilty, pay fines and risk a criminal record and increased insurance premiums, contact our firm to discuss the aggressive legal defense of your charges. We have successfully defended DWI/DUI charges using a broad range of defense tactics. Recent cases we have handled include:
- Our client was charged with drunk driving based on a breath test result. Our investigation revealed that a police department employee was not properly maintaining Breathalyzer machines, and we argued that, without a reliable breath test, the state had no case. The charges were dismissed.
- Our client was charged with DUI/DWI, and the state's primary evidence was a video of a field sobriety test. We succeeded in having the case dismissed because our client did appear drunk in the video.
- Our client drove home at 2:30 a.m., hit a curb and rolled his car, injuring a passenger. We investigated the case and learned that 1) on-the-scene emergency staff didn't note that he was intoxicated, 2) nurse notes from the hospital were missing and, 3) the police arrested our client but conducted no breath or blood test. The case was dismissed on the day of trial.
We can work to prevent the suspension of your driver's license, and can fight for your rights even if you refused to take a breath test. To learn more about your rights, contact attorneys Ralph Manginello and John Butler, who is board-certified in criminal law by the State Bar of Texas.
