Question juridique clé
Whether the call-in action was sufficiently motivated under Arts. 81-82 CPC
Solution extraite
The request was insufficiently motivated because the appellant did not identify concrete, materially connected recourse or warranty claims against the third parties.
Motifs extraits
A call-in action requires only a succinct explanation showing that the asserted claim depends on the outcome of the main action, but the appellant failed to specify the alleged defects, the third parties' roles, and the concrete claims against them. Mere references to general faults or alleged representation were not enough.
