Ban, prohibition. It is a legal term for the deprivation of a right to a person or society, imposed by a judge. The motives are diverse, such as avoiding or preventing a crime, or protecting from oneself a person incapable of making decisions. Whether or not a representative is appointed has nothing to do with interdiction, it would be a subsequent fact, and only if deemed necessary. It has Latin origin in interdict, onis, formed by the prefix inter- ("in the middle, between several") and dictio, onis ("declaration of judgment").
It is a legal process by which it is declared that a person is incapable of making his own decisions at the legal level. It states that he does not have the capacity to exercise his rights. Through this process a judge is given power to someone very close to him to represent him and make decisions that help him to lead a dignified life. In essence it is to choose a healer or protector. It can be declared total or partial. In many cases it is something very necessary, for example in cases of severe mental retardation.
