National Democratic Party organizations are asking a federal appeals court to reconsider a decision that rejected a challenge to a decades-old Florida law about how candidates are listed on election ballots.

The organizations have requested that the full U.S. Court of Appeals for the Eleventh Circuit take up the case after a three-judge panel on April 29 said the Democratic plaintiffs did not have legal standing to challenge the constitutionality of the law. The law requires that candidates who are in the same party as the governor appear first on the ballot, a requirement that Democrats say unfairly favors Republicans in the GOP-controlled state.
