I don't believe any act of Congress can bind the authority of a future Congress (unless it is a Constitutional amendment). Every appropriations bill must be passed by Congress and signed by the President. A veto throws it back to Congress for override (if they can manage it). Legislation can be revoked by a future Congress. This is the threat hanging over all entitlements.
