Questione giuridica chiave
Whether a cross-appeal falls away when the main appeal is withdrawn only in part.
Decisione estratta
No. Under § 251(3) ZPO, the cross-appeal falls away only if the main appeal is withdrawn or not admitted; while the main appeal remains pending, the cross-appeal is treated as an ordinary appeal.
Motivazione estratta
The court held that partial withdrawal of the main appeal did not trigger the statutory consequence for the cross-appeal. The cross-appeal remains procedurally independent as long as the main appeal is still pending.
