The Supreme Court won't hear a challenge to part of Vermont's campaign finance laws that impose contribution limits on political action committees.

The justices on Monday declined to hear an appeal from the Vermont Right to Life Committee, an anti-abortion group. The group argued that Vermont's campaign finance registration, reporting and disclosure requirements for PACs were too broad and unconstitutional.

The group argued that a subcommittee it created should not be subject to Vermont's $2,000 limit on contributions to PACs because the subcommittee does not give money directly to candidates and makes only independent expenditures.

But a federal judge rejected those arguments, finding that there was no clear accounting between the two committees. A federal appeals court agreed.
