The Presentment Clause (Article I, Section 7, Clauses 2 and 3) of the United States Constitution outlines federal legislative procedure by which bills originating in Congress become federal law in the United States. Text The Presentment Clause, which is contained in Article I, Section 7, Clauses 2 and 3, provides: Summary A bill must be passed in identical form by both the House of Representatives and the Senate. It is common practice for each House to pass its own version of a bill, and then to refer the two versions to a conference committee, which resolves disagreements between the two versions, and drafts a compromise bill; the compromise bill can then be voted upon and passed by both Houses in identical form. After a bill passes both Houses, it must be presented to the President for his approval. If the President approves the bill and signs it, then the bill becomes law. If the President disapproves the bill and vetoes it, then he must return the bill, along with a veto message (his objections), back to the House in which the bill was created. A two-thirds majority of both Houses may override the veto, and the bill will become law without the President's signature. In overriding a veto, the votes of both houses must be done by yeas and nays, and the names of the persons voting for and against the bill must be recorded. If, while the Congress is in session, the President does not sign a bill or veto it within 10 days (not counting Sundays) after its presentment, then it automatically becomes law. If a bill is presented on a Monday or Tuesday, the President has 11 real days; otherwise he has 12. If, while Congress is not in session (adjourned), the President does not sign a bill or veto it within 10 days (not counting Sundays) after its presentment, then it fails to become law. This "pocket veto"—so called because the President is then said to have put the bill in his pocket and forgotten about it—cannot be overridden by Congress, but once Congress reconvenes it can pass the same bill again. In addition, Congressional "pro forma" sessions may be used to prevent pocket vetoes. Veto issues Line-item veto 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
