MILWAUKEE — The Milwaukee Police Association is asking a judge to order the city of Milwaukee to obey a new state law that allows public-sector employees to move out of the city.

The lawsuit was filed late Wednesday in Milwaukee County Circuit Court. The police union's lawsuit says the city's failure to comply with the law, signed June 30 by Gov. Scott Walker, deprives officers of their rights to live where they choose, free of the threat of being fired for violating the city's residency rule.

Mayor Tom Barrett tells the Milwaukee Journal Sentinel (http://bit.ly/1bsIVEL ) he continues to believe the 75-year-old residency rule is legal.

Last week, the Common Council voted to continue enforcing the residency rule and authorized City Attorney Grant Langley to file suit challenging the new state law.
