Kernrechtsfrage
Whether the federal appeal was admissible as to the counterclaim under Art. 60(3) OG because the main claim and counterclaim excluded each other.
Extrahierter Entscheid
The claims did not exclude each other. They arose from different legal transactions and each could be decided independently of the other.
Extrahierte Begründung
The main claim concerned payment of the remaining purchase price from the 1902 sale of the business. The counterclaim was based on a separate agreement about housing, household services, and later business assistance. Since neither claim depended on the fate of the other, the special admissibility requirement of Art. 60(3) OG was not met.
