The Supreme Court has refused to block a Minnesota law requiring disclosure of corporate political spending.
The high court without comment turned away a request for an injunction from Minnesota Citizens Concerned for Life.
The Supreme Court earlier this year freed businesses to spend company money on elections, overturning state restrictions on corporate political spending. Minnesota lawmakers responded by enacting disclosure requirements so that corporate campaign spending would be public.
Minnesota Citizens Concerned for Life, the Taxpayers League of Minnesota and a travel agency sued, saying the reporting requirements amounted to a ban on free speech. They want the law stopped while they appeal.
The high court refused.
