The aim of this article is to analyse the procedural position of the suspect and the accused in the case of the offence of sexual exploitation of a minor or a person using reason to a limited extent. The rights conferred and the obligations imposed on those parties in current ecclesiastical legislation require consideration in the context of the applicable principle of the rights of defence, assessing their legal effectiveness. The work concludes with conclusions on the current ecclesiastical regulations governing these matters and proposals for making appropriate changes to them.
