Interdict generally means to ban or prohibit something. It may also refer to an ecclesiastical censure by the Roman Catholic Church withdrawing certain sacraments and Christian burial from a person or all persons in a particular district. For example, Helicopter Interdiction Tactical Squadrons are units that contain Coast Guard armed helicopters and are authorized to employ airborne use of force. The unit’s primary mission is to interdict and stop drug smuggling go-fast vessels.
Interdict could also refer to a person who is deprived of the right to handle his or her own affairs because of mental incapacity. For example, interdiction does not affect the validity of a juridical act made by the interdict prior to the effective date of interdiction. Interdiction as used here refers to the act of depriving a person of the right to handle his or her own affairs because of mental incapacity.
