Key legal question
Whether the request for third-party notice was sufficiently substantiated under Art. 81-82 CPC
Extracted holding
The request was not sufficiently substantiated because the appellant did not clearly identify the materially connected recourse or warranty claims against each third party.
Extracted reasoning
A third-party notice requires a material connection to the main claim and a concise statement of the claims against the third party. The appellant relied on vague allegations and did not explain which defects, contractual breaches, or recourse claims were asserted against the individual third parties.
