To prohibit the District of Columbia from requiring tribunals in court or administrative proceedings in the District of Columbia to defer to the Mayor of the District of Columbia's interpretation of statutes and regulations, and for other purposes.

Summary

Prohibits courts and administrative tribunals in the District of Columbia from giving any deference to interpretations of statutes or regulations advanced by the Mayor or DC agencies when those interpretations are reviewed in judicial or administrative proceedings. It also repeals a recent temporary D.C. amendment passed in 2024, restoring the prior law as if that temporary amendment had never been enacted. The change narrows the legal advantage agencies and the Mayor sometimes obtain when courts evaluate agency orders, decisions, or rules, making judges and tribunals decide the meaning of statutes and regulations without deferring to the executive branch's view.

• Stops courts and administrative tribunals in D.C. from deferring to Mayor or agency interpretations of laws and regulations.
• Applies to review of Mayor and agency orders, decisions, and rules in both judicial and administrative settings.
• Repeals the 2024 temporary amendment that had clarified or altered agency-review rules, restoring earlier law.
• Does not provide new funding or deadlines and includes no stated effective date in the text provided.
• Shifts interpretive authority away from the Mayor and agencies and toward courts and tribunals.
• Likely increases the chance that courts will independently interpret laws and regulations rather than accepting agency explanations.
• Directly affects the District of Columbia legal and administrative process; it does not change federal agency law outside D.C.
