2026.10.19 Supreme Court Order List

The Supreme Court has invited Solicitor General Sauer to submit a brief about whether Iowa can implement Senate File 2340. The Eighth Circuit had previously affirmed a district-court injunction against implementing the law, but DOJ voluntarily dropped its suit after this administration took office. The Iowa Migrant Movement for Justice remains the only plaintiff challenging the Iowa law. In its petition for certiorari, Iowa asked the Court to review the Eighth Circuit's decision to determine if plaintiffs had standing to challenge the law's constitutionality before it went into effect. Bird v. Iowa Migrant Movement for Justice, No. 26-49 (S.Ct.).
