Question juridique clé
Whether V.H. had standing to seek revision alone on behalf of the heirs' estate.
Solution extraite
No. Only the parties to the proceedings leading to the challenged judgment may seek revision, and the heirs had to act jointly; a single heir could not file alone.
Motifs extraits
In the expropriation proceedings, party status belonged only to the heirs as a community, who had to act jointly or through a representative under Art. 602(3) CC. This requirement also applies in revision proceedings.
