The court shall rule, within a period of ten days from the date on which the matter is referred to it, on the application for the opposition to be dismissed made by the author of the acknowledgement, even if he is a minor.
In the event of an appeal, a ruling shall be made within the same time limit and, if the judgment appealed from has dismissed the opposition, the court must rule, even of its own motion.
A default judgment dismissing the opposition to the registration of the acknowledgement or to its mention in the margin of the child’s birth certificate may not be contested.
