There are two pending lawsuits against the presidential debates rule that requires 15% in the polls. One of those cases is Level the Playing Field v Federal Election Commission, in the U.S. District Court in Washington, D.C., 1:15cv-1397. Journalist Sam Husseini, founder of VotePact.org, has written a proposed amicus curiae brief on the side of the plaintiffs. However, the FEC has asked the judge not to let him file that amicus. The judge will decide whether to permit the filing. This will be the first time the judge in this case will have had to make any type of procedural decision that is contested by the two sides to the lawsuit.
The other pending debates case, Johnson v Commission on Presidential Debates, has not had any activity since May 2016.
I never know Amicus briefs could be somehow prevented from filing. Was it an objection to something in the brief itself, or the person or organization that’s submitting it?
