In mid-century America, emergency powers were truly potent. But those days are gone. In his two terms as President, Trump has declared 21 national emergencies, including eight since January 20. This glut of "emergencies" can only further discredit the whole concept. He and his advisors seem to see those as creating nearly magical legal powers, allowing them to deport people without hearings, run roughshod over environmental safeguards, and impose tariffs willy-nilly. They are probably in line for a disappointment. Judges are no longer in awe of emergency powers.
