The question

Whether a candidate for office has Article III standing to challenge the rules that govern the counting of votes in his election.

Bost v. Illinois Bd. of Elections

What the Court decided

Reversed. The Court held that Congressman Bost, as a candidate for office, has standing to challenge Illinois rules on when mail-in ballots are counted, so the Seventh Circuit was wrong to dismiss for lack of standing. A candidate has a personal stake beyond winning, including an interest in a fair and lawful electoral process, and an unlawful election rule can injure a candidate by causing him to lose, requiring him to spend more resources, or damaging his vote share and reputation. A candidate need not show a substantial risk that a rule will change the outcome or block a legally significant vote threshold to establish standing.

The Court's opinion

Roberts, joined by Thomas, Alito, Gorsuch, Kavanaugh

A candidate has a personal stake under Article III that extends beyond winning to an interest in a fair and lawful electoral process. An unlawful election rule can injure a candidate by causing a loss, requiring additional resources, or decreasing vote share and damaging reputation, and reputational harm is a recognized Article III injury. A candidate need not show a substantial risk that a rule will be outcome determinative or will prevent reaching a legally significant vote threshold, because such a requirement would push election disputes to the eve of or after an election, when courts should ordinarily not alter election rules.

Concurring in the judgment

Barrett, joined by Kagan

Barrett agreed that the case should be resolved in Bost's favor on standing but did not join the reasoning of the Court's opinion. The syllabus states only that this opinion concurs in the judgment and does not set out its distinct rationale.

Dissenting

Jackson, joined by Sotomayor

Jackson would not find that Bost has standing. The syllabus identifies this as a dissenting opinion but does not set out its specific reasoning.
