The proliferation of legislative veto provisions in legislation raised a series of constitutional questions. Congress until relatively recently had applied the veto provisions to some action taken by the President or another executive officer—such as a reorganization of an agency, the lowering or raising of tariff rates, the disposal of federal property—then began expanding the device to give itself a veto over regulations issued by executive branch agencies, and proposals were made to give Congress a veto over all regulations issued by executive branch independent agencies.
