In the past decade, there has been an interesting argument in American legal circles concerning the constitutionality of the legislative veto. This type of veto is a provision included in legislation (and in some cases making up the legislation itslef) which allows Congress to cancel executive actions. Soem scholars argue that since such vetoes take place and have the force of law without recieving the signature of the President, nor in many cases the approval of the other House of Congress, they are unconsitutional. Others oint out, however, that for the Congress to exercise a legislative veto both Houses of Congress must have already agreed to, and the President have signed, a bill containing a legislative veto provision. Therefore, they argue, such propositions are indeed constitutional.
