Wyoming Liberty Group attorneys filed an amicus curiae (friend-of-the-court) brief in the Wisconsin Supreme Court today in Three Unnamed Petitioners v. Peterson, a case consolidated with two others in what has become known as the “Wisconsin John Doe Investigation.” The prosecution in each case alleges illegal campaign finance coordination between political groups and ostensibly members of Wisconsin Governor Scott Walker’s campaign. WyLiberty’s brief argues that Wisconsin law governing coordination is unconstitutionally overbroad, and the latest effort to criminalize political participation.
