The U.S. Supreme Court now has promulgated the bizarre illogic that challenges to sketchy voting practices come too soon if they are made before the election but too late if they come afterward. Its silent inaction amounts to an open invitation to serious voting-related mischief in future elections.

In dissent on Monday, Justices Clarence Thomas, Samuel Alito, and Neil Gorsuch were right to blast the other justices’ refusal to hear two Pennsylvania cases. Both cases involved the Pennsylvania Supreme Court’s sudden, unilateral changes last fall to the state’s voting procedures against the express language of laws duly passed by the state’s Legislature.
