MADISON, Wis. (AP) — Wisconsin Gov. Tony Evers on Thursday issued a statewide mask mandate amid a spike in coronavirus cases, setting up a conflict with Republican legislative leaders and some conservatives who oppose such a requirement and successfully sued to kill the governor’s “safer at homeî order.

Evers, a Democrat, declared a new public health emergency and ordered the wearing of masks for anyone age 5 and up starting on Saturday for all enclosed spaces except a personís home. The new order also applies to outdoor bars and restaurants, except when people are eating or drinking.

Anyone who violates the order would be subject to a $200 fine. It is scheduled to run until Sept. 28.

ìThis virus doesnít care about any town, city, or county boundary, and we need a statewide approach to get Wisconsin back on track,î Evers said in a statement, citing the recent rise in cases across the state.

The conservative-controlled Wisconsin Supreme Court in May tossed out an order from Eversí health secretary closing most nonessential businesses in an attempt to slow the spread of the virus.

Republican Assembly Speaker Robin Vos said he opposes a statewide mandate, but he indicated that he wouldn’t sue to stop it like he did the ìsafer at homeî order.

ìThere are certainly constitutional questions here,î Vos said. “I would expect legal challenges from citizen groups.î

Rick Esenberg, president of the conservative Wisconsin Institute for Law and Liberty, which has sued Evers several times, said the governor ìlacks the legal authorityî to issue the order. Esenberg stopped short of promising a lawsuit, saying he was reviewing it.

Republican state Sen. Steve Nass, one of the Legislatureís most conservative members, called for lawmakers to meet in an emergency session to kill the order, which he called ìillegal and unnecessary.î Evers said he would welcome the Legislature meeting to address the pandemic, which it hasn’t done since mid-April. But he said it was a ìsad commentaryî that Nass wanted to reconvene just to kill the mask order.

ìObviously he doesnít believe that masks matter,” Evers said. “Thatís fine, he can be one of those people that flouts the order. But to come in and have the Republicans say essentially we donít believe in science, itís pretty risky business. Itís risky political business and risky health business.î

Vos did not say whether the Legislature would reconvene to kill the order.

Evers has repeatedly cited the earlier Supreme Court ruling as a reason for his reluctance to join 32 other states that have mask mandates. However, the May ruling determined that the state health secretary overstepped her authority with the ìsafer at homeî order; the court did not address the governorís power to issue public health emergencies.

The stateís high court was controlled 5-2 by conservatives when it struck down the earlier order on a split 4-3 decision. But on Saturday, when the mask order takes effect, Justice-elect Jill Karofsky will join the court, narrowing the conservative majority to 4-3 and increasing the odds of the order surviving a legal challenge.

Evers said the rise in COVID-19 cases, not Karofsky’s joining the court, and the fact that not enough people wore masks voluntarily motivated him to act now. Evers had been under pressure from local governments, and even some Democrats, to issue a statewide order. Democratic state Sen. Chris Larson, of Milwaukee, started a petition for a statewide mandate.

ìThe bottom line is we need to keep people safe and this is one way to do it,” he said. “We hope the Supreme Court agrees with us. You never know, it may never end up in the Supreme Court.î

Numerous cities and counties across Wisconsin have already instituted mask mandates, including Milwaukee and Dane counties, Green Bay, Racine, Superior and Whitewater. Eversí order doesnít preempt local governments from enacting even stricter ordinances.

Wisconsin has had more than 52,000 confirmed cases of COVID-19 and 919 deaths from the disease since the pandemic started. That death count is the 28th-highest in the country and the 35th highest per capita, at nearly 16 deaths per 100,000 people. Over the past two weeks, the rolling average number of daily new cases has gone up by 90, an increase of more than 11%.

The virus, although still heavily concentrated in urban areas, is spreading to more rural counties that had largely avoided the disease.
