Latin. For interposing their authority. For interposing or adding their authority. Interdictors and curators ad lites are appointed for this purpose merely, and incur no personal liability, through the performance of the duties of their office. Tutors and curators, the one given as a guardian of the pupil's person, the other, of the minor's estate, are liable for the exercise of a care and diligence, in which persons of the class we are dealing with are not bound. Interdictors give their consent to the deeds of the person interdicted, and by such consent incur no responsibility in warrandice, &c.; while curators ad lites, by their becoming parties to a suit in that character, incur no liability for expenses, &c. Such persons are appointed merely to their respective offices ad præstandam auctoritatem.
