AIDS Vaccine Advocacy Coalition v. Department of State (AIDS USAID 2025)

The Impoundment Control Act prohibits the executive from unilaterally deferring or rescinding appropriated funds, yet the Trump administration's freeze on PEPFAR disbursements did precisely that, halting congressionally allocated funds for a congressionally mandated purpose without seeking the approval required by statute. The Appropriations Clause vests spending authority in Congress, and here the executive's unilateral action to interrupt a continuous funding stream violated that core constitutional allocation when Congress had specifically earmarked those dollars for HIV/AIDS treatment abroad. The court's issuance of a temporary restraining order suggests the plaintiff organizations demonstrated a likelihood of success on their Impoundment Control Act claim, the freeze constitutes a prohibited deferral that requires either congressional acquiescence under the statute's procedures or judicial intervention to restore compliance. The remaining question is whether the executive can articulate any lawful basis for the broader freeze or whether it amounts to an unconstitutional usurpation of Congress's spending power.
