On March 5, two Montana corporations filed a lawsuit in state court to overturn a 1912 state law that makes it illegal for corporations to make expenditures in election campaigns. The lawsuit does not attack the law that makes it illegal for corporations to make contributions. The new Montana lawsuit is, of course, based on the January 2010 U.S. Supreme Court ruling, Citizens United v Federal Election Commission. Here is the Montana complaint, which is Western Tradition Partnership v Attorney General, Montana First Judicial District, Lewis and Clark County, BDV 2010-238.
