My canvas is dauntingly broad, and I must perforce paint with broad strokes. I will focus on administrative law in relation to government regulation, broadly understood. I will first briefly summarize the central elements of administrative law in the United States over the past century and show how they carry forward, reconfigured, into our current era. I will then assess the emerging new methods for achieving regulatory goals in the face of growing administrative fatigue and the implications of those new methods for administrative law. I will conclude with a précis of the emerging international aspects of administrative law.
