West virginia constitution
Article III: bill of rights
Section 11

Political tests, requiring persons, as a prerequisite to the enjoyment of their civil and political rights, to purge themselves by their own oaths, of past alleged offences, are repugnant to the principles of free government, and are cruel and oppressive. No religious or political test oath shall be required as a prerequisite or qualification to vote, serve as a juror, sue, plead, appeal, or pursue any profession or employment. Nor shall any person be deprived by law, of any right, or privilege, because of any act done prior to the passage of such law.
