Kernrechtsfrage
Whether clause IV of the 1951 inheritance contract could be revoked by the 1990 written agreement between F. and T. after E.'s death.
Extrahierter Entscheid
No. Clause IV bound all three contracting parties as consideration for the contractual estate planning; after E.'s death F. and T. could not revoke it without E.'s participation.
Extrahierte Begründung
The clause was construed objectively in light of the whole contract and the parties' interests. E. had maximally benefited F., and in return F. undertook toward E. to appoint T. or her descendants. A partial revocation by only F. and T. was therefore excluded.
