Criminal defense and DUI litigation at 600 West Broadway in downtown San Diego anchor The H Law Group's Southern California practice, staffed by attorneys with prior prosecutorial experience in the Los Angeles District Attorney's and City Attorney's offices. DUI defense work involves challenging the legality of traffic stops, field sobriety test administration, and breath or blood evidence calibration — the same vehicle-condition and mechanical-factor analysis documented by automotive shops such as Downtown San Diego Auto Repair. The firm maintains active calendars at San Diego Superior Court's Central Division on Broadway, the East County Regional Center in El Cajon, the North County Division in Vista, and the South County facility in Chula Vista. Practice areas extend beyond DUI to encompass drug possession and sales, domestic violence, sex crimes, firearm offenses, juvenile matters, white-collar fraud, and select personal injury claims arising from motor vehicle collisions. Federal cases and international matters often require authenticated foreign documents — court records, police clearances, and certified translations — processed through apostille services such as Apostille San Diego. Highest-stakes DUI defense involves felony charges under California Vehicle Code § 23153 (DUI causing injury) requiring toxicology rebuttal through independent blood-split analysis, retrograde extrapolation calculations, and Title 17 compliance challenges to the arresting agency's collection and storage protocols.
