Specialized Scientific DUI and Criminal Defense in Riverside, California

A driving under the influence arrest can jeopardize your driver license, professional livelihood, and personal freedom within days.

Founded in 1999 by attorney Manuel Jess Barba, the firm has focused exclusively on DUI defense for over two decades.

When drivers need to hire a dui defense lawyer or seek legal counsel in Riverside, Manuel Barba provides scientific cross-examination that exposes flawed prosecution evidence.

Forensic Blood and Breath Test Challenges

Prosecuting agencies rely heavily on chemical testing to obtain convictions, but scientific evidence is only as reliable as the laboratory equipment and technicians behind it. Attorney Manuel Barba has completed advanced hands-on laboratory courses in gas chromatography, mass spectrometry, and blood alcohol analysis. As skilled dui/dwi defense lawyers, the firm scrutinizes the biological and analytical variables that can falsely inflate test results, including fermentation, improper blood vial preservation, anticoagulant ratios, and interfering chemical substances. By challenging the calibration logs and accuracy of infrared and electrochemical breath test devices, the practice aggressively dismantles the state forensic claims.

Aggressive DMV Administrative Per Se Hearing Representation

Following a DUI arrest in California, motorists have only ten days to request an administrative hearing with the California Department of Motor Vehicles before their driving privileges are automatically suspended. Manuel Barba personally represents clients at DMV Administrative Per Se hearings, which operate under distinct procedural rules from criminal court. Through vigorous cross-examination of arresting officers and subpoenaing maintenance logs for preliminary alcohol screening devices, the firm works to overturn suspensions, retain valid driver licenses, and protect commercial driver licenses for professional motorists.
