States sued the Obama administration over things that the administration required them to do. It's possible that the Trump administration will roll back regulations or repeal laws. You can sue the Federal government for requiring your state to enact an environmental law. You can't sue them for repealing that law if it doesn't require the state to do anything. So we don't know if the laws passed by congress will warrant any legal work.
So what we have here is a legislature is fighting a battle against a non-existent opponent (until January 20) over non-existent laws. And spending money to do it. Kudos.
