Honestly, I was almost starting to appreciate being left behind while everyone else was given the chance to prepare for the mess Earth had gotten itself into. On a side note, it turns out I'm pretty good at hunting monsters. Though dragons and such are a bit out of my league. Just a bit. I survived dozen-something kobolds that wanted me dead, and now it's time to pay back their leader.

Natural Resources Defense Council, this judicial review has been highly deferential: courts must uphold agency interpretations of unclear laws as long as these interpretations are "reasonable." But the Chevron doctrine faces backlash from constitutional scholars and, now, from Supreme Court justices who insist that courts, not administrative agencies, have the authority to say what the law is. Recognizing that Congress cannot help relying on agencies to carry out laws, Merrill rejects the notion of discarding the administrative state.
