First, there is significant judicial approval of this proposition. Most notable is the Court's decision in Myers v. United States, 272 U.S. 52 (1926). There the Court sustained the President's view that the statute at issue was unconstitutional without any member of the Court suggesting that the President had acted improperly in refusing to abide by the statute. More recently, in Freytag v. Commissioner, 501 U.S. 868 (1991), all four of the Justices who addressed the issue agreed that the President has "the power to veto encroaching laws . . . or even to disregard them when they are unconstitutional." Id. at 906 (Scalia, J., concurring); see also Youngstown Sheet & Tube Co. v. Sawyer, 343 U.S. 579, 635-38 (1952) (Jackson, J., concurring) (recognizing existence of President's authority to act contrary to a statutory command).
Second, consistent and substantial executive practice also confirms this general proposition. Opinions dating to at least 1860 assert the President's authority to decline to effectuate enactments that the President views as unconstitutional. See, e.g., Memorial of Captain Meigs, 9 Op. Att'y Gen. 462, 469-70 (1860) (asserting that the President need not enforce a statute purporting to appoint an officer); see also annotations of attached Attorney General and Office of Legal Counsel opinions. Moreover, as we discuss more fully below, numerous Presidents have provided advance notice of their intention not to enforce specific statutory requirements that they have viewed as unconstitutional, and the Supreme Court has implicitly endorsed this practice. See INS v. Chadha, 462 U.S. 919, 942 n.13 (1983) (noting that Presidents often sign legislation containing constitutionally objectionable provisions and indicate that they will not comply with those provisions).

. The President's office and authority are created and bounded by the Constitution; he is required to act within its terms. Put somewhat differently, in serving as the executive created by the Constitution, the President is required to act in accordance with the laws -- including the Constitution, which takes precedence over other forms of law. This obligation is reflected in the Take Care Clause and in the President's oath of office.
