Bost v. Illinois Bd. of Elections

Background

In 2022 Illinois allowed election officials to count mail‑in ballots that were postmarked or certified by Election Day and received within two weeks afterward. Congressman Michael Bost and two other candidates sued the Illinois State Board of Elections, saying the delayed counting violated federal statutes that set Election Day. The district court dismissed for lack of standing and the Seventh Circuit affirmed. The Supreme Court granted review and reversed, deciding on standing on January 14, 2026.

Reasoning

The Court addressed whether a candidate has a personal stake to sue over the rules that govern vote counting. The majority held that candidates have a particularized interest in a fair and accurate process. An unlawful counting rule can injure candidates by costing them an election, forcing extra campaign expenses, or reducing their vote share and harming reputation. The Court explained candidates need not show a substantial risk of losing or a specific monetary loss to have Article III standing. Chief Justice Roberts wrote the opinion, joined by four other Justices.

Real world impact

The ruling lets candidates challenge state vote‑counting procedures in federal court before or during an election more easily. That could increase pre‑election litigation by candidates seeking to enforce or block state rules about late ballots. The decision resolves only standing; the Supreme Court did not rule on whether Illinois’s law violates federal statutes. The lower courts will now consider the merits on remand.

Dissents or concurrances

Justice Barrett (joined by Justice Kagan) concurred in the judgment, arguing Bost had traditional pocketbook injury from costs to monitor counting. Justice Jackson (joined by Justice Sotomayor) dissented, warning the majority’s rule departs from usual injury requirements and risks opening many candidate‑led challenges.
