Challenging DUI stops on a lack of probable cause: Part I

For a drunk driving charge to be legitimate, police need to prove that they followed proper procedure. For instance, defense attorneys may try to challenge how a field sobriety test was administered. And at the heart of any DUI conviction is this question: did the officer have probable cause to pull over the suspect?

Wisconsin Appeals Court upholds DUI stop based on cautious driving

Last week, we wrote about the Wisconsin man who was convicted of DUI despite the fact that he was never pulled over and no one even saw him driving. The Wisconsin Supreme Court upheld the ruling based solely on evidence from an electronic monitoring device the man was wearing.
