Gerwig v. Gordon
Annotate this CaseThe issue this case presented was one of first impression for the Court of Appeal: whether a licensee can rebut an Evidence Code presumption that chemical blood tests were properly conducted, and the results are thus reliable. Plaintiff William Lee Gerwig crashed into the back of another vehicle at an intersection. He was thrown from his motorcycle and landed on the asphalt. California Highway Patrol Officer Jacob Rebelo responded to the scene and spoke with Gerwig while he was receiving medical attention. Based on his lethargic responses, the smell of alcohol, and his inability to recall the collision details, Rebelo suspected Gerwig was intoxicated. Rebelo arrested Gerwig for driving under the influence of alcohol (DUI), and watched while state-certified phlebotomist Francisco Moreno collected two vials of blood using a nonalcoholic swab to clean the site. Rebelo took the vials himself and entered them into evidence. Test results from Gerwig’s blood draw showed a blood-alcohol concentration (BAC) of .25 percent. At the Department of Motor Vehicle hearing, Gerwig’s counsel called an employee of Specimen Specialists of America, Inc. (SSI), the company that dispatched phlebotomist Moreno to draw Gerwig’s blood. Through the employee’s testimony, counsel demonstrated that certain SSI procedures were out of compliance with state regulations that govern blood test procedures. In particular, Moreno was functionally unsupervised and the manual that SSI provided for phlebotomists had not been approved by a physician and surgeon. After eliciting testimony to demonstrate these procedural failings, counsel argued that the test results could not be relied on due to SSI’s regulatory violations. The Court of Appeal concluded that licensees rebut the Evidence Code presumption only when they cast doubt on the integrity of the test. "It is not enough to show a violation of governing regulations that has only a tenuous connection to the accuracy of the results. Here, because plaintiff proved a regulatory violation with only an indirect and speculative relationship to the manner in which the blood test was conducted, and thus the reliability of the test results," the Court affirmed the order denying mandamus relief.
