The Review of Agency Action Clarification Amendment Act of 2025 aims to amend the District of Columbia Administrative Procedure Act by codifying agency deference. The bill stipulates that a reviewing court or tribunal must defer to an agency's reasonable interpretation of the statutes or regulations it administers, as long as that interpretation is not plainly wrong or inconsistent with the statutory or regulatory language or the legislature's intent. This amendment seeks to clarify the standards for judicial review of agency actions, ensuring that agencies have the authority to interpret the laws they enforce.

The bill includes specific amendments to Section 110 of the District of Columbia Administrative Procedure Act. It replaces the phrase "So far as necessary" with "Subject to subsections (c) and (d) of this section and so far as necessary" in subsection (a)(1). Additionally, it introduces new subsections (c) and (d), which explicitly outline the deference that courts must give to the Mayor or agency's reasonable interpretations during reviews of orders, decisions, or rules. These changes are intended to reinforce the principle of agency expertise in the interpretation of laws and regulations.
