Facts of the case
Following the Civil War, Congress and Missouri adopted provisions that required persons in specified professional occupations to take an oath that they have never given aid to the rebellion and secession. Missouri convicted a priest who refused to take the oath. A former Confederate congressman asked the Supreme Court for permission to practice without taking the federal oath.
Do the state and national oaths violate prohibitions against ex post facto laws and bills of attainder of the Constitution?
