The Supreme Court on Monday declined to review limits on coordinated election spending between national party committees and federal candidates, meaning the restrictions will remain in place.

By not taking up the case of Cao v. Federal Election Commission, the Supreme Court let stand a decision by the 5th Circuit Court of Appeals that affirmed restrictions on how much parties can spend after consultation with Congressional campaigns.

Lawyers for former Rep. Anh “Joseph” Cao (R-La.) argued that limits on coordinated spending infringe on the national party committee’s freedom of speech.

“This morning the Supreme Court deferred to precedent and declined to hear this attack on the long-standing limits on party coordinated spending,” said attorney Tara Malloy of the Campaign Legal Center. “Plaintiffs’ challenge would have blown huge loopholes in the federal campaign finance laws and enabled large-scale circumvention of the individual contribution limits.”
