On December 4, independent presidential candidate Robert F. Kennedy, Jr., and some supporters filed a federal lawsuit against the Utah independent presidential petition deadline of January 8, 2024. Maxfield v Henderson, 4:23cv-112. Here is the motion for injunctive relief.
In 1983 the U.S. Supreme Court ruled in Anderson v Celebrezze that independent presidential petition deadlines cannot be as early as March. In the wake of that decision, lower courts struck down deadllines in April, May, and June. In 1987, there was a moment at which every state had a means for an independent presidential candidate to get on the ballot in July, August, or September.
But during the years since, many states have moved their deadlines to earlier dates. But Utah is the most extreme. In 2022 the legislature moved the deadline from August to early January. And the Utah deadline realistically is in December, because January 8 is the deadline for the counties to have checked the signatures, which means they must be submitted in December.
In 1984, Lyndon LaRouche sued Utah over its April 15 deadline, and the state admitted it could not defend its deadline, and moved it to September, later moving it to August.
