You've been busted by police for a DUI, and a blood test came back showing you're over the legal limit. That's the end, right? How can you challenge that?
Actually, there are several potential ways to challenge that kind of evidence. Just because your blood alcohol content tested over 0.08%, the legal limit in California, doesn't mean it's an open and shut case.
We're not saying cases like the Annie Dookhan lab scandal are going to happen all the time. But blood tests are done by people and people make mistakes. You just need to know where to look for them.
