Sentence revoked because judgment granted claim based on cause of action different from that alleged by plaintiffs.

The Tribunal da Relação de Lisboa revoked the appealed sentence due to a fundamental procedural error. The lower court granted the plaintiffs' request based on a cause of action that differed from the one actually alleged by them in the initial complaint. Consequently, the appellate court determined the original judgment was null and void because it failed to adjudicate the specific legal basis presented by the parties.
