Latin. On the ground of interdiction. Interdiction, now scarcely known in practice, was a means formerly adopted for the protection of those who were weak, facile, and easily imposed upon ; and also for the protection of those who, being reckless and profuse, were unable to manage their estate with care and prudence. Interdiction was either judicial or voluntary ; and in whichever of these modes the interdiction was effected and imposed, any disposition of heritage thereafter by the interdicted, without the consent of his interdictors, was liable to reduction on the ground of interdiction, except where the conveyances were onerous and rational.
