United States v. MacIntosh

Background

The case concerns an immigrant born in Canada who came to the United States in 1916 and declared his intention to become a citizen in 1925. He applied for naturalization, but the district court denied his application because he would not promise in advance to bear arms in defense of the United States unless he personally believed a war was morally justified. The court of appeals reversed, and the Supreme Court reviewed the question.

Reasoning

The Court looked to the Naturalization Act, which requires an oath to "support and defend" the Constitution and that applicants be "attached to the principles of the Constitution." The majority said those statutory requirements allow courts to probe an applicant’s beliefs and to ensure the oath will be taken without mental reservations. The applicant had written and oral statements saying he would judge for himself whether a future war was morally justified and might withhold armed or moral support. Relying on an earlier decision addressing similar objections, the Court concluded those qualifications showed he was not sufficiently attached to the Constitution and properly denied his application.

Real world impact

The decision permits denial of citizenship when an applicant expressly reserves the right to refuse military support on personal moral or religious grounds. It signals that courts may scrutinize applicants’ stated beliefs at naturalization hearings. Congress, however, retains power to change the legal treatment of conscientious objection or exemptions.

Dissents or concurrances

A dissent argued the issue is one of law, noted the applicant’s strong character and wartime service roles, and said the oath historically was not meant to force people to abandon religious scruples about bearing arms; Congress should speak clearly if it intends otherwise.
