Mr. St. Louis leads a firm that is uniquely qualified to handle DUI and other criminal charges, helping clients achieve the best possible outcome.
Joseph P. St. Louis Stands Apart
Known in the Legal Community
Mr. St. Louis has built a reputation in the legal community that has earned him the respect and recognition of his peers. He was the president of Arizona Attorneys for Criminal Justice, a statewide defense organization with over 400 members. At the request of the then-presiding chief judge of the Pima County Justice Courts, Mr. St. Louis served as a part-time Justice of the Peace in 2003.
Understanding the Science
A high BAC doesn't mean your case is hopeless. After becoming frustrated with an analyst who would never answer his questions, Mr. St. Louis learned the science of blood testing himself. He's become so well-versed in it, he teaches judges and juries about laboratory errors, and teaches fellow lawyers how to defend blood alcohol tests. He once got a complete dismissal on a .27.
Track Record of Success
Mr. St. Louis has protected many Tucson residents from harsh penalties by securing not-guilty verdicts, case dismissals, and generous plea bargains. Our clients have noted Mr. St. Louis's personable demeanor, clear explanations, and extreme diligence when handling their cases.
AN ADVOCATE IN YOUR CORNER
• Mr. St. Louis has tried over 200 cases to juries, on both misdemeanor and felony charges, in federal court and state courts throughout Arizona.
• He has argued cases before the Arizona Court of Appeals, the Arizona Supreme Court, and the Ninth Circuit Court of Appeals.
• He was lead counsel in Pima County’s first death penalty case tried completely to a jury in state court.
• He was found to be qualified as “Learned Counsel,” a designation reserved for only the most qualified attorneys handling death penalty cases, in federal court.
• Mr. St. Louis has the unique distinction of having had two back-to-back first-degree murder cases in which the judges dismissed all murder charges during the trial.
• In 2013, Mr. St. Louis was one of four lawyers who litigated a 17-day hearing in the Maricopa County Superior Court challenging how blood testing is performed in the Scottsdale City Crime Laboratory. The hearing resulted in the judge suppressing all blood evidence in 11 felony cases, after finding the results to be unreliable.
SPEAKING ENGAGEMENTS
Mr. St. Louis has been asked to give over 150 lectures and trainings by State Bar Associations and defense organizations throughout the United States in the last 25 years.
