Federal district courts are hearing the first major legal challenges to 'pocket rescissions'—a tactic that lets presidents refuse to spend money Congress has already appropriated.

A pocket rescission occurs when the President simply doesn't spend funds Congress allocated, effectively canceling the money without legislative approval. That differs from a standard rescission, which requires both presidential action and congressional agreement within 45 days under the Impoundment Control Act of 1974.

Congress passed the Impoundment Control Act after President Richard Nixon had aggressively withheld appropriated funds. The law set strict rules: presidents could propose rescissions, but Congress had to approve them or the money went out anyway.

These new cases force federal judges to directly weigh presidential authority against Congress's constitutional power of the purse. Plaintiffs argue that pocket rescissions violate the separation of powers, since only Congress controls spending decisions. Courts will examine whether the President's actions constitute an unlawful impoundment or fall within permissible executive authority.

The stakes are real. If courts side with the President, future chief executives gain broad power to reshape budgets after Congress votes. If courts back Congress, they curtail executive flexibility in managing federal accounts. District court rulings will likely set the template for how the Supreme Court eventually weighs the two competing powers.
