Background

Three named petitioners brought the case on their own behalf and for others allegedly similarly situated, challenging federal immigration action associated with the Alien Enemies Act. The district court had not certified a class and had declined to do so.

After the government removed all three named petitioners from the United States, the petitioners moved in the Fifth Circuit to add five new class representatives. The government did not oppose the motion. The proposed representatives had differing immigration circumstances, including approved asylum, current Temporary Protected Status, and an application for lawful permanent residence.

The Court’s Holding

The en banc Fifth Circuit denied the motion without prejudice. It emphasized that no certified class existed and that the petitioners had not demonstrated that the proposed representatives were similarly situated to putative class members or otherwise satisfied Rule 23’s requirements. Their individual immigration circumstances instead suggested that they might be uniquely situated, including because they might not be removable under authorities other than the Alien Enemies Act.

The court also concluded that the district court was better positioned to make the factual findings required for class certification and representative adequacy. Its ruling did not prevent the district court from later permitting the addition or substitution of representatives, allowing an amended petition, or certifying a class. Judge Haynes concurred in the denial.

Key Takeaways

  • The Fifth Circuit would not add new class representatives on appeal where the district court had not certified—and had previously declined to certify—a class.
  • An unopposed substitution request still requires a showing that the proposed representatives satisfy Rule 23 and are similarly situated to the putative class.
  • The denial was without prejudice, leaving the district court free to consider new representatives, an amended petition, and class certification.

Why It Matters

The order underscores that replacing named plaintiffs after their claims may have become moot is not automatic, particularly before any class has been certified. Even when the opposing party does not object, proposed representatives must fit the putative class and satisfy Rule 23.

The decision also directs fact-intensive questions about new representatives and class certification back to the district court, while preserving a potential path for the litigation to continue there.
