Questions Presented

  1. Whether a candidate for office has Article III standing to challenge rules governing the counting of votes in the candidate's election without showing a substantial risk of losing the election, failing to achieve a legally significant vote threshold, or suffering a separate financial or reputational injury.
  2. Whether Congressman Bost adequately alleged a concrete and particularized interest in the integrity and legality of the election process.

Holdings

  1. A candidate for office has a concrete and particularized Article III interest in the rules governing the counting of votes in the candidate's election and may challenge those rules without showing a substantial risk that the rules will cause an election loss, reduce the candidate's vote share, or increase campaign costs.
  2. Article III does not require a candidate challenging vote-counting rules to plead or prove a substantial risk of electoral loss, failure to meet a legally significant vote threshold, or a likely disadvantage relative to a competitor.

Key quotations

Factual background

Illinois law requires election officials to count mail-in ballots postmarked or certified no later than election day if received within two weeks after election day. Congressman Michael Bost and presidential-elector nominees Laura Pollastrini and Susan Sweeney alleged that counting such ballots conflicted with federal statutes designating election day. Bost alleged that late ballot counting would require his campaign to continue organizing and monitoring the election for fourteen additional days, incurring costs and potentially affecting his vote margin, reputation, and electoral legitimacy.

Procedural history

In May 2022, Bost, Pollastrini, and Sweeney sued the Illinois State Board of Elections and its executive director, principally arguing that Illinois's post-election ballot-receipt rule conflicted with 2 U.S.C. § 7 and 3 U.S.C. § 1. The Northern District of Illinois dismissed the case for lack of standing. The Seventh Circuit affirmed, concluding that the alleged monitoring costs, competitive injury, and inaccurate-tally injury were insufficiently concrete or speculative. The Supreme Court reversed and remanded.

Remand instructions

The case was remanded to the lower courts for further proceedings consistent with the Supreme Court's holding that Congressman Bost has Article III standing.
