Key legal question
Whether the alleged later-discovered original version of the expert-hearing plan qualified as a new and material fact under Art. 137 lit. b OG.
Extracted holding
The earlier version of the plan, even if newly discovered, would not have changed the prior judgment and was therefore not material.
Extracted reasoning
Revision requires a new fact that could alter the factual basis and lead to a different result. The court held that its earlier decision did not depend on the disputed plan version, because it had already found that the private expert had no procedural right to reply and that the proceedings were otherwise fair.
