§ 1531. Effect of judgment. 1. A final judgment in favor of either party, in an action brought as prescribed in this article, is conclusive, as to the title established in the action, against the other party, known or unknown, including an infant, a mentally retarded person, a mentally ill person, or an alcohol abuser, and also against every person claiming from, through or under that party, by title accruing after the filing of the judgment roll, or of the notice of the pendency of the action, as prescribed by law; also against each person not in being or ascertained at the commencement of the action, who by any contingency contained in a devise or grant or otherwise, could afterward become entitled to a beneficial estate or interest in the property involved, provided that every person in being who would have been entitled to such estate or interest if such event had happened immediately before the commencement of the action is a party thereto, or that a guardian ad litem is appointed, as prescribed by section 1513.

2. A new trial of said action after judgment shall not be granted as a matter of right, but the court may, in its discretion in the interest of justice, grant a new trial upon an application made by any party within one year after said judgment. Upon any new trial of an action brought as prescribed in this article, the record of the evidence given upon the previous trial may be again offered to the court by either party, and may be received in evidence, in case the same evidence cannot be again procured. The courts may make such rules and orders as to preserving the record of the evidence given in such actions and perpetuating the proofs produced therein, either with or without the awarding of any other relief to the party whose proofs are so perpetuated, as shall be necessary or proper, and may embrace such directions in the judgment.
