In 2004, a voter in Ohio moved to intervene in a 1981 District of New Jersey case, complaining that widespread voter-registration challenges in Ohio violated a consent decree between the two major political parties in the New Jersey case. On the day before the election, the district court in New Jersey granted injunctive relief. A panel of the court of appeals, over a dissent, denied the defendants a stay, but the full court ordered en banc review on election day. Because the plaintiff was allowed to vote, the appeal was subsequently declared moot. In 2016, a suit was again filed in the District of New Jersey to enforce and extend the consent decree. Related actions were filed in six other states, plaintiffs were denied immediate relief there, and the actions were dismissed voluntarily after the election. A little more than one year later, the consent decree was terminated.
