Sorry, the OP got it WRONG.
The State of NJ is NOT being sued. Phil Murphy, in his official capacity as Governor is being sued. The suit seeks injunctive relief to an Executive Order.
YWN posted a news article about a Lakewood Rabbi joining the suit and posted the actual suit filed in US District Court.
All my previous comments about needing the state’s permission to sue the state were a waste of my time, since the state was not being sued.
