The governor’s coronavirus orders have for months banned local governments from taking more restrictive or lenient steps than the state. But the new set of rules he signed on Wednesday specified for the first time that cities and counties can’t require the use of masks or other face coverings.

That could improve the state’s standing in a courtroom fight against a string of cities that have defied Kemp’s emergency order by requiring masks. Savannah led that charge earlier this month, and since then other cities including Atlanta, Athens and Augusta have followed suit.

The governor’s order also requires vulnerable people to shelter in place, restricts gatherings of more than 50 people, and mandates that restaurants and other businesses take numerous precautions.
