Below is an article out of New Jersey detailing a class action law suit seeking to overturn 20,000 DUI convictions. It is alleged that an officer with the New Jersey Highway Patrol missed a step when calibrating thier breathalyzer machine, thereby invalidating thoursands of breath test results. This is a different type of machine than what is used in South Carolina, but South Carolina machines still require humans to service them, and humans are fallible.
