Question juridique clé
Whether the calling-in action was sufficiently motivated under Arts. 81 and 82 CPC
Solution extraite
The application was insufficiently motivated because it did not concretely state and substantiate the materially connected claims against the third parties.
Motifs extraits
A calling-in action requires a materially connected recourse or warranty claim and only a concise statement of the intended claim against the third party. Here, the appellant failed to identify specific claims, defects, or the role of each third party, so the appellate court could refuse joinder.
