The American Civil Liberties Union and two abortion rights groups Tuesday filed a federal lawsuit to stop a new state law aimed at banning a controversial abortion procedure.
The new law is set to take effect on March 30.
It was approved by the state Legislature last year after thousands of voters signed petitions to allow the bill become a law with only the approval of the House and Senate. Gov. Granholm vetoed the legislation the first time around.
The ACLU, the Center for Reproductive Rights and Planned Parenthood Federation of America say the law could be interpreted as a ban on all abortions.
But supporters say the bill is needed to stop that particular type of abortion critics call partial-birth abortion.
