Question juridique clé
Whether the collocation complaints were wrongly dismissed because the pledged claims and security rights were treated as legally irrelevant in the bankruptcy of Z. AG
Solution extraite
The dismissals could not stand because the lower court had not examined whether the creditors' rights could be collocated after the avoidance judgment and the later pledge arrangements.
Motifs extraits
The avoidance duty primarily binds the avoidance defendant, but third-party successors may be affected only under Art. 290 SchKG. The bankruptcy administration may raise a paulian defense in the collocation action, and if that defense fails, the material validity of the pledged claims and security rights must be examined.
