Kernrechtsfrage
Whether the bank could rely on alleged general terms requiring immediate notice of account disputes.
Extrahierter Entscheid
No; the alleged general terms were not properly pleaded and proven, so the court could not treat them as binding.
Extrahierte Begründung
The bank bore the burden of alleging and proving the extinguishing facts. Unilateral notices on account statements did not establish agreement to the terms, and there was no manifest inadvertence.
