Code of Civil Procedure Article 507-1

In cases where a third party who is legally interested in an action was prevented from intervening in that action due to reasons not imputable to himself/herself, and thus was unable to present means of attack or defense which may have affected the result of the judgment, such third party may, by naming the parties to that action as co-defendants, initiate an opposition action against that final and binding judgment to seek the revocation of the portion of such judgment prejudicial to him/her, except where such party should seek remedies through other legal proceedings.
