DMV v. Client (2012)
California is an implied-consent state where every driver, by receiving a driver’s license, consents to make themselves available to a chemical test when they are driving under the influence. The penalties for refusing a chemical test, eiher breath, urine, or blood, are heavy - 1 year suspended license for the first refusal.
In 2012, Margolin and Lawrence won a DMV Refusal Hearing where the client refused to take a chemical test at a DUI checkpoint - an exceptionally rare result.
