This Article examines over 500 nationwide-injunction cases and shows that a surprising participant is influencing the result: an outsider who has joined as an intervenor. Judicial discretion over intervention functionally gives courts control over how nationwide-injunction cases proceed, or whether they proceed at all. With few principles guiding that discretion, procedural rulings can appear to be influenced by the court’s own political leanings, undermining public confidence in the court’s decision on the merits. This Article represents the first scholarly examination of the significant role that intervention plays in nationwide-injunction suits. More broadly, this Article uses intervention to explore the function of procedural rules and the federal courts in a democratic system. Finally, this Article offers two reforms that would promote procedural values and cabin the role of the federal courts in ideological litigation.
