Decision: Garland v. Aleman Gonzalez, 596 U.S. 543 (2022).

Noncitizens detained under 8 U.S.C. section 1231(a)(6) during withholding proceedings obtained classwide injunctions requiring bond hearings after six months. On June 13, 2022, the Supreme Court addressed whether section 1252(f)(1) permitted that classwide injunctive relief. For a detained person, the practical distinction is between the procedure a class asks a lower court to impose for everyone and the relief that may be available in an individual case.

Section 1252(f)(1) limits remedial authority

Except for the Supreme Court, courts may not enjoin or restrain the operation of the specified immigration provisions other than with respect to an individual noncitizen against whom proceedings have been initiated.

The injunction altered statutory operation

The lower courts required bond hearings and related release procedures. The majority held that the orders restrained the statute’s operation even though the plaintiffs said they were seeking its correct enforcement. The remedial limit did not depend on first deciding whether the plaintiffs’ statutory interpretation was right. Slip opinion, pages 6–10.

Classwide relief was the dispositive problem

The individual exception did not authorize an injunction covering an entire class. The text preserves case-specific relief for an individual while withholding the lower courts’ power to issue the challenged classwide injunction.

Individual relief and constitutional claims

The decision concerned classwide injunctive relief under the covered statutes. Individual relief and constitutional merits remained separate questions. The Court did not decide whether the same restriction reached declaratory relief, or resolve the possible limits on a lawsuit with multiple named plaintiffs. It reversed and remanded the two class-injunction judgments. Slip opinion, page 7 footnote 2 and pages 10–11.

Key takeaways

• Identify the statutory detention provision and the precise remedy requested.
• Separate the merits of a detention challenge from section 1252(f)(1)’s remedial limit.
• Frame individual relief distinctly from classwide operational commands.
• Do not read the decision as eliminating every individual constitutional remedy.
