The Supreme Court reinstated a South Carolina voting rule that requires a witness to sign mail-in ballots, overturning a lower court ruling that temporarily blocked the requirement amid potential safety concerns related to the coronavirus. While the Supreme Court did not provide a full explanation for the ruling, Justice Brett Kavanaugh issued a concurring opinion, noting that the Supreme Court has “repeatedly emphasized that federal courts ordinarily should not alter state election rules in the period close to an election.”
Extra: The court noted that any ballots cast prior to its ruling yesterday (and received within the following two days) may not be rejected for failing to comply with the reinstated witness requirement.
