Question juridique clé
Whether the seller's conduct amounted to an anticipatory breach allowing the buyer to claim the contractual penalty of CHF 25,000.
Solution extraite
Even if an anticipatory breach could be inferred, the buyer lost the right to rely on it because he did not immediately declare that he would forgo performance and invoke the penalty; his later withdrawal was too late.
Motifs extraits
Under Art. 107 and 108 OR, a creditor may dispense with a cure period only if the debtor clearly and definitively refuses performance. In case of anticipatory breach, the creditor must promptly elect the remedy; otherwise the right is forfeited.
