Daniel Seeger had a "belief in goodness and virtue for their own sakes, and a religious faith in a purely ethical creed."
Most of these draft court cases were over religious reasons for opposition to the war. Those who believed that war was against their religion desired a conscientious objectors exemption. Daniel Seeger believed that he was a conscientious objector and refused to go when he was drafted. Seeger was arrested, tried, and convicted but later appealed and won, his reasoning being that his conviction was in violation of the 1st Amendment.
