Article II, Section 1, Clause 8:
Before he enter on the Execution of his Office, he shall take the following Oath or Affirmation:– I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States.
Several Presidents have relied on the oath, alone or in conjunction with the Take Care Clause,[1](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn1art2 " U.S. Const. art. II, § 3. ") for authority to take actions necessary to “preserve, protect and defend the Constitution.” President Thomas Jefferson contended that the oath obligated him to suspend prosecutions under the Sedition Act, which Jefferson had repeatedly claimed was unconstitutional.[2](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn2art2 " Letter from Thomas Jefferson to Abigail Adams (July 22, 1804), in 1 The Adams-Jefferson Letters 274, 275–76 (Lester J. Cappon ed., 1959) (suggesting that the “obligations of an oath to protect the constitution, violated by an unauthorized act of Congress,” compelled Jefferson to “arrest [the] execution at every stage” of the Sedition Act). ") President Andrew Jackson relied in part on the presidential oath in vetoing a bill rechartering the Second Bank of the United States.[3](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn3art2 " Veto Message (July 10, 1832), in 3 A Compilation of the Messages and Papers of the Presidents 1139 (James D. Richardson ed., 1897) [hereinafter Messages and Papers]. ") He advanced the view that the presidential oath, as well as the general oath provision in Article VI,[4](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn4art2 " U.S. Const. art. VI, cl. 3. ") grants each branch of government an independent power to interpret the Constitution.[5](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn5art2 " Messages and Papers, supra note 3, at 1145 ( “Each public officer who takes an oath to support the Constitution swears that he will support it as he understands it, and not as it is understood by others.” ). ") Partially repudiating the Supreme Court’s decision in McCulloch v. Maryland,[6](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn6art2 " 17 U.S. (4 Wheat.) 316 (1819). ") which upheld the constitutionality of the national bank, President Jackson suggested that “[t]he authority of the Supreme Court must not . . . be permitted to control the Congress or the Executive when acting in their legislative capacities . . . .” [7](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn7art2 " Messages and Papers, supra note 3, at 1145. ")
President Abraham Lincoln relied on the oath to defend his decision to suspend unilaterally the privilege of the writ of habeas corpus,[8](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn8art2 " The writ of habeas corpus, which allows detained individuals to challenge their detention in court, is protected from suspension by the Constitution. U.S. Const. art. I, § 9, cl. 2; see . ") claiming that the presidential oath required the President to disregard “a single law” if doing so would preserve the Union.[9](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn9art2 " Abraham Lincoln, Message to Congress in Special Session (July 4, 1861), in Abraham Lincoln’s Speeches and Letters, 1832–1865, at 173 (Paul M. Angle ed., 1957) ( “[W]ould not the official oath be broken if the government should be overthrown, when it was believed that disregarding [a] single law would tend to preserve it?” ). ") President Lincoln similarly justified his position on emancipation of enslaved persons during the Civil War by invoking the presidential oath:
I did understand . . . that my oath to preserve the Constitution to the best of my ability, imposed upon me the duty of preserving, by every indispensable means, that government—that nation—of which that Constitution was the organic law. . . . I felt that measures, otherwise unconstitutional, might become lawful, by becoming indispensable to the preservation of the Constitution, through the preservation of the nation. Right or wrong, I assumed this ground, and now avow it. I could not feel that, to the best of my ability, I had even tried to preserve the Constitution, if, to save slavery, or any minor matter, I should permit the wreck of government, country, and Constitution all together.[10](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn10art2 " Letter from Abraham Lincoln to Albert G. Hodges, editor of the Frankfort, Kentucky ‘Commonwealth’ (Apr. 4, 1864), in Abraham Lincoln’s Speeches and Letters, supra note 9, at 264. ")
During President Andrew Johnson’s impeachment trial, his counsel alluded to the theory that the oath might grant the President power, but only in passing.[11](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn11art2 " Cong. Globe Supp., 40th Cong., 2d Sess. 314 (1868) (suggesting that a President is bound by oath to disregard a law that “upon its very face [is] in flat contradiction to plain express provisions of the Constitution” ). ") President Johnson’s lawyers argued that the oath might allow or obligate the President to disregard an unconstitutional law.[12](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn12art2 " Id. ") By contrast, the impeachment managers appeared to take the position that a President would violate their oath by doing so.[13](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn13art2 " Id. at 270 (statement of Rep. George S. Boutwell, on behalf of the Managers) ( “He must take the law and administer it as he finds it without any inquiry on his part as to the wisdom of the legislation . . . . If in any particular, by implication or construction, he assumes and exercises authority not granted to him by the Constitution or the laws he violates his oath of office . . . .” ). ") Chief Justice Chase, who presided over the impeachment trial, had no official duty to resolve this question, but appeared to side more closely with the view of the President.[14](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn14art2 " Letter from Chief Justice Chase to Gerrit Smith (Apr. 19, 1868), in J.W. Shuckers, The Life and Public Services of Salmon Portland Chase 578 (1874) ( “How can the President fulfill his oath to preserve, protect, and defend the Constitution, if he has no right to defend it against an act of Congress sincerely believed by him to have been passed in violation of it?” ).

Although several Presidents have cited the presidential oath as providing a basis for executive action, the Supreme Court has not expressly addressed whether the oath may be relied upon for that purpose.[15](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn15art2 " The Court has at times referred to the oath in passing as support for implied executive powers, such as the power to engage in electronic surveillance. United States v. U.S. Dist. Court (Keith), 407 U.S. 297, 310 (1972) ( “[T]he President of the United States has the fundamental duty . . . to ‘preserve, protect and defend the Constitution of the United States.’ Implicit in that duty is the power to protect our Government against those who would subvert or overthrow it by unlawful means.” ). ") In the case Lear Siegler, Inc., Energy Products Division v. Lehman, the Ninth Circuit rejected this notion.[16](https://www.law.cornell.edu/constitution-conan/article-2/section-1/clause-8/presidential-oaths-effect-on-executive-power#fn16art2 "
