Kernrechtsfrage
Whether the heirs' accounting request against Y. SA was time-barred under the contractual accounting claim
Extrahierter Entscheid
The request was time-barred because the right to accounting under Art. 400 CO is subject to a ten-year limitation period running from the end of the mandate.
Extrahierte Begründung
The heirs succeed to the deceased client's contractual right to information; since the relevant bank relationships ended in 1990 and 1993, the claim filed in 2005 was prescribed.
