The only recourse is pulling the state plan authorization. There is no court option. Arizona is currently under this threat over their refusal to adopt the first ETS in the summer.

My "court" thought was based on some action by the feds, for example puling of the state plan authorization, becing challenged in a court.

But great point, the first move is not by a court, but by OSHA. I think it is beyond disagreement that state plans exist by dint of federal approval.
