Jan. 14 (UPI) -- Political candidates have legal standing to sue states that count mail-in ballots received after election day, the Supreme Court ruled Wednesday.

The court voted 7-2 to allow lead plaintiff Rep. Mike Bost, R-Ill., to continue his lawsuit against the Illinois State Board of Elections and its executive director for counting mail-in ballots that are received after a designated voting day.

Also suing are presidential elector nominees Laura Pollastrini and Susan Sweeney.

Article III of the Constitution requires plaintiffs to have a "personal stake" in a case in order to have legal standing to sue, and an unlawful election rule can cause injury in many ways, the court ruled.
