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.

HR 3766 prohibits the District of Columbia from requiring courts or administrative bodies to automatically accept the Mayor's interpretation of laws or regulations when reviewing the Mayor's decisions or rules. It specifically blocks DC from making tribunals defer to the Mayor's or agencies' interpretations of statutes during legal challenges. The bill also repeals a temporary 2024 law (D.C. Law 25-290) that had allowed such deference. This change directly affects how DC courts and administrative proceedings handle appeals of Mayor-led agency actions. The policy shift ensures independent review of interpretations rather than automatic acceptance of the executive branch's stance.
