Bloomberg BNA:

A case set to be argued March 15 before a federal appeals court in New York could challenge the trend toward deregulated campaign spending that has accelerated since the 2010 Supreme Court ruling in Citizens United v. Federal Election Commission, according to a brief filed in the case (Vermont Right to Life Committee v. Sorrell, 2nd Cir., No. 12-2904, argument 3/15/13).

The brief, filed by a group of officials from nine states, asked the court to restore the power of states to limit contributions to political action committees (PACs), including so-called super PACs, which now take unlimited contributions for independent campaign expenditures.
