The Wisconsin Supreme Court on Friday ruled 4-3 to reinstate the use of most ballot drop boxes across the crucial battleground state, overturning a decision it made less than two years ago that banned the use of most of those boxes.

“Our decision today does not force or require that any municipal clerks use drop boxes,” the decision Friday read. “It merely acknowledges … that clerks may lawfully utilize secure drop boxes in an exercise of their statutorily-conferred discretion.”
