Appeal as from an abuse
"Appeal as from an abuse" (French: appel comme d'abus) is a legal term applied in the canon law of the Catholic Church, meaning originally a legal appeal as recourse to the civil forum (court) against the usurpation by the ecclesiastical forum of the rights of civil jurisdiction. It could also mean (vice versa) a recourse to the ecclesiastical forum against the usurpation by the civil forum of the rights of ecclesiastical jurisdiction.
