In Dickinson v. United States, 1953, the U.S. Supreme Court ruled in favor of a Jehovah's Witness who had been convicted for refusing induction into military service during World War II due to his religious beliefs. The court held that the Selective Service System had acted arbitrarily and capriciously by denying him conscientious objector status without any basis in fact. The petitioner, Elijah Dickinson Jr., argued that he was entitled to an exemption from military service as a minister of religion under the Universal Military Training and Service Act. However, his application was denied by local draft boards and affirmed on appeal up to the President. The Supreme Court reversed these decisions stating that there must be some factual basis for denial of conscientious objector status beyond mere disbelief or disagreement with applicant’s claim or sincerity thereof. This case set precedent for future cases involving claims of conscientious objection based on religious belief against compulsory military service; it underscored respect for individual conscience rights even amidst national security concerns during wartime.

In the dissenting opinion for Dickinson v. United States, Justice Jackson argued that the majority's decision to exempt a Jehovah’s Witness from military service based on his religious beliefs was inconsistent with previous rulings and could potentially undermine national security. He contended that this interpretation of the law would allow anyone claiming sincere religious or philosophical objections to avoid military service, which could be exploited by those seeking to evade their civic duties. Furthermore, he expressed concern about how such determinations of sincerity and religiosity were being made by Selective Service boards without clear guidelines or standards. This lack of clarity could lead to arbitrary decisions and potential discrimination against certain religions or belief systems.
