Kernrechtsfrage
Whether the donor could invoke the lack of public deed form for the donation promise despite prior conduct.
Extrahierter Entscheid
B. was entitled to rely on the formal nullity; invoking the defect was not a manifest abuse of rights on the established facts.
Extrahierte Begründung
The promise of donation was knowingly not made in public-deed form by both parties; the agreement had not been essentially performed beyond temporary use of the garage, and in such a case art. 2(2) CC does not create a right to compel performance of a formally invalid contract.
