Prohibition on the admission of evidence regarding facts covered by the seal of confession in administrative proceedings. Administrative proceedings exclude the possibility of a priest obtaining the status of a witness in relation to facts he learned during confession. The provisions of public law do not contain a definition of a clergyman or confession, referring in this respect to the internal law of churches and trade unions. The seal of confession is an integral part of the celebration of this sacrament, from which no one can ever release a clergyman. Respecting the seal of confession is an expression of respect for the constitutional principle of autonomy and independence of religious communities that freely regulate the principles of faith and worship.
