Key legal question
Whether V.H. had standing to seek revision alone on behalf of the heirs' estate.
Extracted holding
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.
Extracted reasoning
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.
