In Catholic canon law, an interdict /ˈɪntərdɪkt/ is an ecclesiastical censure, or ban that prohibits persons, certain active Church individuals or groups from participating in certain rites, or that the rites and services of the church are bannished from having validity in certain territories for a limited or extended time.
Before 1983, interdicts were either personal, if applied directly to a person, wherever he was, or local, if applied directly to a locality and only indirectly to the people in that place whether permanently or only on a visit. Only the Holy See was empowered to impose a general interdict on a diocese or state or a personal interdict on the people of a diocese or country, but bishops too could impose a general interdict on a parish or on the people of a parish or a particular interdict on a place (such as a church or oratory, an altar or a cemetery) or a person.
A local interdict forbade in general the public celebration of sacred rites. Exceptions were made for the dying, and local interdicts were almost entirely suspended on five feasts of the year: Christmas Day, Easter Sunday, Pentecost, Corpus Christi and the feast of the Assumption of Mary. Besides, in the case of a general local interdict, it remained permissible to celebrate in the cathedral or the only church in a town, but without any solemnity such as the ringing of bells and the playing of music, Mass, baptism, confession, and marriage.
