Overview
- The Court heard arguments focused solely on Article III standing, not the merits of Illinois’ rule that counts mail ballots postmarked by Election Day if received within 14 days.
- Conservative justices questioned tying standing to a candidate’s odds of winning, with Chief Justice John Roberts warning that forecasting election outcomes is a “potential disaster.”
- Rep. Mike Bost’s counsel argued candidates face concrete “pocketbook” and reputational harms from prolonged counting, while Illinois said any injury is speculative or self‑inflicted.
- The Trump administration backed limited candidate standing, and the ACLU supported access‑to‑courts principles even as it opposes Bost on the merits of the late‑ballot policy.
- A decision expected by June 2026 could revive Bost’s suit and affect similar challenges in states that count late‑arriving ballots, including pending disputes in Mississippi and Louisiana.
