H.Res. 603 is a congressional resolution reaffirming core constitutional principles including the separation of powers, checks and balances, and the rule of law. The resolution, submitted by a bipartisan group of representatives in July 2025, condemns any efforts by public officials to undermine these principles—specifically calling out attempts to ignore court orders, consolidate power in a single branch, withhold congressionally approved funds, or use executive authority to arbitrarily prosecute political opponents. The resolution emphasizes Congress's constitutional powers over spending, oversight, and investigations, and asserts that appropriations made by Congress are binding law rather than mere recommendations. This is a symbolic measure with no funding or enforcement mechanisms; it calls on all public officials to uphold the Constitution and reject actions that threaten the constitutional order. The resolution was referred to the House Judiciary Committee for consideration.
