This canon gives us interesting information about the clergy that preferred civil to ecclesiastical justice. The council is strongly opposed to it, and threatens the clerics (including bishops) who do it in criminal cases with demotion, even if they are proven innocent. If they win something in a civil case, they have to renounce it if they are to retain their office. There are two textual traditions, evenly distributed, one of which ("in locum suum non restituatur") seems to suggest that the cleric was suspended from his office when a criminal case was pursued against him.
The second part of the canon, not cited here, stresses that going to secular judgement means disrespecting the Church as such; the authority of Paul (1 Cor 6,1-8) is invoked to strengthen this opinion.
