The Review of Agency Action Clarification Amendment Act of 2025 amends the District of Columbia Administrative Procedure Act to codify agency deference as it existed prior to the Supreme Court's decision in Loper Bright Enterprises v. Raimondo. The bill clarifies that a reviewing tribunal must defer to an agency's reasonable interpretation of a statute or rule it administers when the statute or rule is silent or ambiguous on a specific issue, provided that the interpretation is not plainly wrong or inconsistent with the language of the statutes or rules or the intent of the legislature or agency.

Key amendments include the replacement of the phrase "So far as necessary" with "Subject to subsections (c), (d), and (e) of this section and so far as necessary" in subsection (a)(1). Additionally, new subsections (c), (d), and (e) are added, which outline the conditions under which a reviewing tribunal should defer to an agency's interpretation and the factors to consider in determining the reasonableness of that interpretation. These changes aim to ensure that agency interpretations are respected while allowing for the continued development of the law of deference.
