No, they said that "one state cannot have standing on another", AS FAR AS THE TEXAS-LED ATTEMPT TO ENFORCE THE CONSTITUTION. COWARDS.
PLEASE SHOW US ALL THE MAIL IN BALLOT STANDARDS THAT WERE "CHANGED BY REPUBLICAN LEGISLATURES", AS THE CONSTITUTION CLEARLY REQUIRES, AND AS YOU FALSELY CLAIMED HAPPENED.
They said those filing the suit did not have standing. For the Supreme Court to have original jurisdiction it must be a dispute between states. If the dispute is between citizens of different states then it begins at the district court level.
The Supreme Court acted properly by not interfering in the laws of states. Even if they had accepted the case the lawsuit presented no evidence of any voter fraud and nothing to overturn an election.
