Article 1, Section 8, Clause 1 — Presidential And Congressional Power In The Vietnam War

prev | next

Article I, Section 8, Clause 11:

[The Congress shall have Power . . . ] To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water; . . .

After North Vietnamese patrol boats reportedly attacked U.S. naval vessels in international waters in Southeast Asia in August 1964, Congress enacted a joint resolution, known as the Gulf of Tonkin Resolution, authorizing the President to “take all necessary measures to repel any armed attack against the forces of the United States and to prevent any further aggression.” [1](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn1art1 " Pub. L. No. 88-408, 78 Stat. 384 (1964), repealed by 84 Stat. 2055 (1971). See also, U.S. Involvement in the Vietnam War: the Gulf of Tonkin and Escalation, 1964, U.S. Dep’t of State: Office of the Historian, >https://history.state.gov/milestones/1961-1968/gulf-of-tonkin (last visited Sept. 10, 2024); 2 Am. Mil. Hist., The U.S. Army in a Global Era 306 (2d ed. 2005), . ") As the conflict unfolded and spread beyond Vietnam’s borders, some Members of Congress questioned whether military operations had become so extensive that they exceed the Gulf of Tonkin Resolution’s scope and required a declaration of war.[2](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn2art1 " See, e.g., U.S. Commitments to Foreign Powers, Hearings before the S. Comm. on Foreign Relations, 90th Cong. 121 (1967) [hereinafter U.S. Commitments Hearing]. ") President Lyndon Johnson claimed the Constitution alone provided sufficient authority and would have done so even if Congress had never enacted the Gulf of Tonkin Resolution.[3](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn3art1 " See The President’s News Conference (Aug. 18, 1967), in U.S. Commitments Hearing, supra note 2, at 126 ( “We stated then, and we repeat now, we did not think the resolution was necessary to do what we did and what we are doing.” ). ") Executive branch attorneys, on the other hand, relied on a combination of the President’s Article II powers and the Gulf of Tonkin Resolution as domestic legal authorities.[4](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn4art1 " See

The State Department also cited the United States obligations under the South East Asian Collective Defense Treaty. Id. at 485. In an executive branch legal opinion addressing introduction of U.S. forces into Cambodia, then-Assistant Attorney General (and later Chief Justice of the Supreme Court) William Rehnquist took the view that the military action fell “short of war” and was “the sort of tactical decision traditionally confided to the Commander in Chief in the conduct of armed conflict.” [5](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn5art1 "

In 1971, Congress passed and the President signed a bill repealing the Gulf of Tonkin Resolution[6](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn6art1 " Pub. L. No. 91-672 § 12, 84 Stat. 2055 (1971). ") and calling for the “prompt and orderly” withdrawal of U.S. troops at the “earliest practicable date.” [7](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn7art1 " Pub. L. No. 92-156 § 601(a), 85 Stat. 430 (1971). ") U.S. troop presence diminished considerably during this period as the Nixon Administration carried out a policy to transfer control of the conflict to South Vietnamese forces, but the Nixon Administration continued aerial campaigns after the Gulf of Tonkin Resolution was rescinded.[8](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn8art1 " See Jennifer K. Elsea et. al., Cong. Rsch. Serv., R41989, Congressional Authority to Limit Military Operations 21 (2013), >https://crsreports.congress.gov/product/pdf/R/R41989. ") Congress eventually passed, and President Nixon signed, legislation prohibiting use of appropriated funds for military operations in Southeast Asia[9](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn9art1 " See, e.g., Pub. L. No. 93-50 §§ 304-07, 87 Stat. 99 (1973); Pub. L. No. 93-52 § 108, 87 Stat. 130 (1973). ") and setting a ceiling on U.S. civilian and military personnel in Vietnam.[10](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn10art1 " Foreign Assistance Act of 1974, Pub. L. No. 93-559 § 38(f)(1), 88 Stat. 1795. ") By 1973, Congress’s dissatisfaction with presidential use of armed forces without congressional authorization or consultation led it to enact the War Powers Resolution over President Nixon’s veto.[11](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn11art1 " See Pub. L. No. 93-148 § 1(c), 87 Stat. 555 (1973) (codified at 50 U.S.C. § 1541(c)). For broader discussion of the War Powers Resolution and its troop withdrawal deadlines, see and Matthew C. Weed, Cong.

Federal courts considered several cases contesting the constitutionality of military action in Vietnam and Southeast Asia, but no case successfully challenged the conflict or permanently constrained presidential action. Some lower courts held that these cases presented nonjusticiable political questions,[12](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn12art1 " See, e.g.,

(affirmed without written opinion). When the Supreme Court declined to adjudicate similar cases, Justice Douglass frequently dissented and contended that the Supreme Court should resolve the underlying separation of powers dispute. See, e.g., (Douglas, J., dissenting from denial of petition for certiorari); (Douglas, J., dissenting from denial of motion for leave to file bill of complaint). ") Other lower courts took a different approach and concluded that the question of whether congressional authorization was required for military action could be justiciable in some scenarios.[14](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/presidential-and-congressional-power-in-the-vietnam-war#fn14art1 "
