It usually takes the Supreme Court about three months after an argument to issue a decision. The biggest rulings tend not to arrive until late June, no matter how early in the term the cases were argued.
But the case argued Thursday is different, and the nation can expect a prompt ruling.
The justices put the case on a fast track when they agreed to hear it, and the parties have asked for a quick decision, saying that voters must know soon whether former President Donald J. Trump is eligible to be on the ballot. The question, Mr. Trump’s lawyers told the justices, “urgently require this court’s prompt resolution.”
Lawyers for the six Colorado voters who challenged Mr. Trump’s eligibility asked the court to rule by Sunday, the day before the state mails primary ballots. “Having a decision on the merits by Feb. 11 would ensure that every in-state Colorado voter knows of this court’s decision before receiving their ballot and casting their primary vote,” the challengers told the court.
That deadline seems unrealistic. But the court may well act before the Super Tuesday on March 5, when Colorado and 14 other state hold their presidential primaries.
