The Michigan attorney general has lost a court challenge to remove seven of 11 members of Detroit's school board. The Detroit Free Press says Attorney General Bill Schuette sued last year, arguing that the seven board members are illegally holding office. The seven were elected by district in 2011; Michigan law says a school system must have 100,000 students or more to be considered a first-class district that is able to elect board members by district. Detroit's enrollment dropped below 100,000 students in 2008-09. But the judge ruled that state law doesn't address how an enrollment decline affects the status of a first-class school district. The law also does not address how board elections should be handled after a school system drops below the 100,000 enrollment threshold.
