There have been some cases decided. Gun stores were allowed to reopen last week in MA by court order after being deemed non-essential, but they are of course specially protected. Churches have won court cases to be able to hold in-person services, also a specially protected class.

But then there was the case of the barber shop in Michigan which just today a judge denied a preliminary injunction where the state was trying to keep them closed.
