Wisconsin Gov. Tony Evers had postponed in-person voting for the spring election set to take place Tuesday.
The governor took the action via executive order.
In a televised press conference, Evers justified the action by citing concerns about holding in-person voting during a period in which a safe at home order is in effect to help slow the spread of COVID-19 coronavirus.
“I have an obligation to keep people safe,’ Evers said.
Republican legislative leaders appealed the decision to the state Supreme Court.
The Supreme Court voted 4-2 to overturn the executive order, with Justice Daniel Kelly, who is on the ballot, not voting.
