Democratic Gov. Tom Wolf asked the Pennsylvania Supreme Court on Friday to intervene in his dispute with legislative Republicans who have voted to end pandemic restrictions he imposed in March to slow the spread of the new coronavirus.

Republican majorities in the House and Senate, with a few Democrats in support, voted this week to end the state’s emergency disaster declaration that Wolf has used to shut down “non-life-sustaining” businesses, ban large gatherings and order people to stay at home.

Wolf asked the state’s high court to uphold the shutdown. He said that his gradual reopening plan is working, pointing to a downward trend in the number of new virus infections in Pennsylvania even as cases rise in nearly half the states.

“Pennsylvania’s measured, phased process to reopen is successful because of its cautious approach that includes factors relying on science, the advice of health experts and that asks everyone to do something as simple as wearing a mask when inside or around others outside the home,” Wolf said in a news release. “We will continue to move forward cautiously.”

Wolf has been easing restrictions in vast swaths of the state, including on Friday when he announced that another eight counties would be moving to the least restrictive “green” phase of his reopening plan. But gyms, barber shops, theaters and similar businesses in the state’s highly populated southeast corner remain closed, and many types of businesses statewide must abide by occupancy limits.
