The Presentment Clause, which is contained in Article I, Section 7, Clauses 2 and 3, provides: Every Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the President of the United States: If he approve he shall sign it, but if not he shall return it, with his Objections to that House in which it shall have originated, who shall enter the Objections at large on their Journal, and proceed to reconsider it.
Every Order, Resolution, or Vote to which the Concurrence of the Senate and House of Representatives may be necessary (except on a question of Adjournment) shall be presented to the President of the United States; and before the Same shall take Effect, shall be approved by him, or being disapproved by him, shall be repassed by two thirds of the Senate and House of Representatives, according to the Rules and Limitations prescribed in the Case of a Bill.The Supreme Court decision in Clinton v. City of New York, 524 U.S. 417 (1998), struck down as unconstitutional the Line Item Veto Act of 1996, holding that the line-item veto violated the Presentment Clause.
The Supreme Court also found the legislative veto unconstitutional in Immigration and Naturalization Service v. Chadha, 462 U.S. 919 (1983), as violating the Presentment Clause and bicameralism.
Some scholars believe this exclusion was not for religious reasons, but intended to support a deliberative process in which the President would consult and seek advice regarding the merits of the proposed law.
"[3] Specifically, the Court stated: Even the Constitution of the United States, which is supposed to have little touch upon the private life of the individual ... provides in Article I, Section 7, a provision common to many constitutions, that the executive shall have ten days (Sundays excepted) within which to determine whether he will approve or veto a bill.
