The ACLU has filed a federal lawsuit on behalf of four Michigan teens who were required by police to blow into a Breathalyzer at parties.
The ACLU says Michigan is the only state in the country where police don't need a search warrant to require pedestrians under age 21 to take an alcohol test. If they refuse, they face a $100 fine.
Saginaw Valley State University honors student Katie Platte blew into a Breathalyzer at a party last year. She say Michigan law presumes young people guilty until proven innocent. Platte figures to have success in court.
US District Judge David Lawson of Bay City, who in 2003 struck down a Bay City ordinance that was nearly identical to the state law, will hear the case.
