  2. On May 14, 2021, the Mississippi Supreme Court issued a 6-3 decision stating that it is impossible for any petition to meet the state's distribution requirement and has been impossible since congressional reapportionment in 2001. The six justices wrote, "... Whether with intent, by oversight, or for some other reason, the drafters of [the constitutional signature distribution requirement] wrote a ballot initiative process that cannot work in a world where Mississippi has fewer than five representatives in Congress. To work in today’s reality, it will need amending—something that lies beyond the power of the Supreme Court."
