Most of the Justices (yes, including Roberts) were pretty tough on Administration lawyers trying to defend the mandates. Big issue is whether or not the Fed. Gov’t can dip down to the local level to force madates on private businesses through what are basically executive orders with no action from Congress.
There seems to be a good chance the Court rules against the mandates in general. They may uphold Federal power over Federal employees but the mandates on businesses, which are crucial to what Biden is pushing for, will probably fall.
It will be a victory for conservatives and the American people IF the Court quashes mandates for private businesses (although the usual Nattering Nabobs of Negativism will show up and try to spin it as a victory for the Deep State).
