A shift in the deference given to administrative agencies' interpretations of statutes has occurred, with the concept of "delegated discretion" emerging. The change appears to be related to a supreme court decision, possibly involving the overturning of Chevron deference, although the implications and scope of this development are still being explored. The impact of this shift is being considered in various contexts, including federal and state nondelegation doctrines, agency decision-making, and specific areas such as kids' privacy and environmental policy.
