Supreme Court Chief Justice John Roberts on Monday night rejected an emergency request by the National Association of Manufacturers, delivering the day’s second punch to the group’s fight against a new lobbying law.

The trade group sought relief from the Supreme Court after the U.S. Court of Appeals for the D.C. Circuit earlier rejected the group’s appeal to postpone enforcement of a key part of the Honest Leadership and Open Government Act. The provision requires trade groups to name certain dues-paying members.
