Kernrechtsfrage

Extrahierter Entscheid
The ordinary civil-law appeal was inadmissible because the value in dispute did not reach the minimum and no question of principle was shown.
Extrahierte Begründung
The dispute turned on the application of Art. 264 CO to the specific guarantee letter, which did not raise a legal issue of general importance.
