Conscientious objection

Conscientious objection refers to the claim for exemption from compulsory military service based on ethical, moral, or religious beliefs. This phenomenon has been particularly contentious during periods of war, especially when conscription is enforced, leading to complex legal debates about who qualifies for such exemptions. Historically, the practice of conscription dates back to the American Revolution, with significant instances during the Civil War and the establishment of military drafts in the 20th century. The U.S. Supreme Court has faced challenges in defining conscientious objector status, primarily focusing on the First Amendment's guarantees of free exercise and establishment of religion.

While the military transitioned to an all-volunteer force in 1973, reducing the frequency of conscientious objection claims, issues surrounding this status have persisted, particularly during conflicts in Iraq and Afghanistan. Notably, diverse religious beliefs influence the perspectives on conscientious objection, with some sects advocating for complete pacifism while others permit participation in "just wars." The complexities of these beliefs have sparked discussions about fairness and discrimination in the treatment of individuals seeking exemption. Recent global conflicts, including hostilities involving Israel and Hamas, have further led military personnel to seek conscientious objector status, reflecting ongoing ethical dilemmas faced by service members.

Description: Claim of exemption from compulsory military service, or at least from combat, based on ethical, moral, or religious grounds. Only claims based on religious principles raise constitutional issues.

Significance: Controversies surrounding conscientious objection are most likely to occur when the nation is at war and begins conscription, especially during an unpopular war. The Supreme Court struggled with controversies over how conscientious objector status is to be defined and who is exempted from military obligation.

Conscription to raise an armed force dates to the American Revolution, when some American colonies imposed requirements of military service on their male citizens. Additionally, the North and South each resorted to a military draft during the Civil War. In the twentieth century, conscription became well established as an efficient means for Congress to carry out its Article I authority “to raise and support armies.” The requirement to answer the call to arms has been limited to males into the twenty-first century, and the decision to exempt from obligatory military service on religious grounds was left to the political discretion of Congress. However, when Congress has adopted policies respecting conscientious objection, the constitutional problems that have resulted have been many and complex.

Religious Objectors

Controversies over conscientious objection arise from the unprecedented religious diversity of the American population, including a number of pacifist sects whose adherents avoid all participation in warfare and others permitting their adherents to participate only in “just wars.” Quite apart from the practical observation that pacifists make ineffectual soldiers, it might be thought that the First Amendment’s free exercise of religion clause would require Congress to exempt religious pacifists from military service, rather than force citizens to act contrary to religious conscience. However, the Supreme Court, in the Selective Draft Law Cases (1918), rejected such a claim, calling “its unsoundness . . . too apparent to require us to do more.” Even so, it had historically been the practice to grant exemptions to members of specific sects, at least when the latter were sufficiently prominent to secure the respect of the surrounding community. For example, New York’s first constitution, adopted in 1777, exempted Quakers from military service, although it also authorized the legislature to impose special fees in lieu of service. The federal draft acts of 1864 and 1917 accommodated religious objections to military service, though in different ways. The Civil War–era Enrollment Act of 1864 permitted substitution or commutation, mechanisms typically used by members of pacifist religious groups. By contrast, the Selective Service Act of 1917 explicitly recognized conscientious objection, while authorizing the conscription of such individuals into noncombatant or alternative forms of service.

This deference to religious principle generates its own constitutional problems, however. When membership in a pacifist sect becomes the basis for granting exemption from the draft, Congress would seem to violate the establishment of religion clause. Although the precise meaning of this clause has been the subject of continuing debate, courts and commentators generally agree that it prohibits Congress from favoring or discriminating among religious sects. Identifying Quakers, or any other specific sects, as recipients of conscientious objector status might be viewed as creating a privilege on the basis of religious belief. Even without naming specific sects, Congress faces a dilemma in finding a religiously neutral way of limiting the exemption, lest it become universal. Thus, the crux of the problem is to define a category of persons who might claim exemption from conscription in a way that violates neither the free exercise nor the establishment of religion clauses of the First Amendment. Any attempt to do so exposes the potential conflict between these two clauses.

A Careful Approach

Perhaps in recognition of this dilemma, the Court usually avoided constitutional rulings in conscientious objector cases, purporting to resolve them by statutory interpretation. However, despite its ruling in the 1918 draft law cases, in the twentieth century, the Court clearly attempted to interpret draft statutes in a way that makes them conform to the complex demands of the First Amendment. It is equally clear that Congress struggled with this issue, but was less sensitive to the requirements of the establishment of religion clause than the Court.

The Draft Act of 1917, for example, extended conscription to all able-bodied males, exempting members of any “well-recognized religious sect or organization” that forbade its “members to participate in war in any form.” This formulation privileged adherents of well-recognized religions, compared with religions lacking such organization or doctrinal clarity, thereby conferring conscientious objector status on Quakers but denying it to equally sincere objectors who did not belong to any such organization. It also denied conscientious objector status to those whose religious principles included distinctions between just and unjust wars, such as Roman Catholics.

The Selective Training and Service Act of 1940 sought to avoid the problem of sectarian discrimination by dropping the requirement that the conscientious objector be a member of a well-recognized sect. An individual had only to object to war in any form based on “religious training and belief.” This standard was refined in 1948, when Congress defined religious training and belief to include “an individual’s belief in a relation to a Supreme Being involving duties superior to those arising from any human relation, but [excluding] essentially political, sociological, or philosophical views or a merely personal moral code.” Even with these enhancements, however, the definition of conscientious objection failed to achieve religious neutrality because it excluded religions that did not include a supreme being—such as Buddhism—and religions that were not monotheistic—such as Hinduism.

In United States v. Seeger (1965), the Court sought to remedy this problem by interpreting this definition of religious training and belief as including any “sincere and meaningful belief which occupies in the life of its possessor a place parallel to that filled by the God of those admittedly qualifying for the exemption.” Although this interpretation sought to eliminate the problem of discrimination among sects, it did so by extending conscientious objector status to many persons holding “political, sociological or philosophical views or merely a personal moral code,” people to whom Congress had specifically denied such an exemption, as the Court recognized in Welsh v. United States (1970). However, in Gillette v. United States (1971), the Court held that exemption from service could still be denied to those whose religiously based objection did not include war in all forms. Thus, those who believed in fighting only just wars still could not qualify for conscientious objector status.

In Clay v. United States (1971), the Court established a three-part test by which conscientious objector claims were to be evaluated, requiring that the claim be based on a religious belief as defined in Seeger, that the objection is to war in all forms, and that the claim is sincere.

The All-Volunteer Force

In 1973, after US military forces withdrew from Vietnam near the end of the Vietnam War (1955-75), the US military changed how it secured personnel to fill its ranks. Entry into the armed forces was done almost exclusively on a volunteer basis. This new model was termed the "All-Volunteer Force," or AVF. As such, this action greatly reduced the issue of conscientious objection to military service, at least in terms of the numbers seeking this deferment. 

In other respects, the issue was made more complex. This was demonstrated during the Persian Gulf War (1991), the wars in Iraq (2003–11), and the wars in Afghanistan (2001–21). Unlike previous wars, contemporary military service needed to be self-initiated, and prospective recruits affirmed their willingness to participate in combat to recruiters. These conditions raised questions on the rationales and the validity of those seeking this status. Conscientious objectors within the military ranks nonetheless persisted, even after the introduction of the AVF. The initiation of combat operations in Afghanistan and Iraq likely precipitated an increase in those seeking this status, as many who had volunteered for service later attempted to reverse their original decision. The Government Accountability Office indicated that during the period from 2002 to 2006, 425 members had applied for conscientious objector status. Fifty-three percent of the applications were approved. For some, conscientious objections were formed from experiences that occurred during an initial deployment. They subsequently requested a change in their status to forestall additional deployments.

Following the October 2023 initiation of hostilities between Israel and Hamas, questions surrounding conscientious objection again entered public discussion in the United States. Media reporting and advocacy organizations noted that some US service members explored or initiated conscientious objector applications, citing moral, ethical, or religious objections related to US military assistance to Israel and the conduct of the conflict. As in earlier periods, such cases were handled through established Department of Defense procedures, which required individualized review and did not exempt service members from duty unless formally approved.
