318 U.S. 80 (1943)
Securities and Exchange Commission v. Chenery Corp.
Whether an administrative agency can justify its decision based on legal grounds different from those originally articulated.
An administrative agency's decision must be based on the grounds articulated at the time of decision-making and cannot be defended on new grounds during judicial review.
The U.S. Supreme Court held that the Securities and Exchange Commission had the authority to make decisions based on its evolving understanding of the laws it administers. However, such decisions must be justified with clear reasoning at the time they are made, not retrospectively.
The SEC v. Chenery Corp. decision is pivotal for law students as it sets a foundational precedent regarding the principles of administrative discretion and the obligation for agencies to provide reasoned justifications for their actions. The case underscores the requirement for transparency in administrative decision-making, which continues to impact the framework of judicial review and regulatory compliance. Understanding this ruling helps illustrate the balance between deference to specialized expertise and the need for accountability in agency conduct.
