Such composition does not prevent the prosecution of the public ministry. A party may add to his composition a stipulation for a penalty against him who shall fail to execute it. Compositions only regulate the disputes which are therein comprised, whether the parties have manifested their intention by special or general expressions, or whether such intention can be understood as a necessary consequence of what is expressed. If the party having compounded for a claim which he had in his own right, becomes afterwards possessed of a similar claim in right of another person, he is not bound by the anterior composition so far as regards the claim acquired. Composition made by one of the interested parties does not bind others interested, and cannot he objected by them.
Compositions have, between the parties, the authority of a matter decided in the last resort.
They cannot be impeached on the ground of error in law, or on the ground of injury. Nevertheless, a composition may be rescinded where there is mistake in the person, or in the object of the litigation. It may be so in all cases where there is fraud or violence. There is equal foundation for an action of annulment against a composition, when it was made in execution of a void title, unless the parties have expressly treated respecting such nullity. Composition made upon documents which have subsequently been discovered to be false, is entirely null.
