59.(1) Where there is a breach of warranty by the seller, or where the buyer elects or is compelled to treat any breach of a condition on the part of the seller as a breach of warranty, the buyer is not by reason only of such breach of warranty entitled to reject other goods; but he may(a) set up against the seller the breach of warranty in diminution or extinction of the price; or(b) sue the seller for damages for breach of warranty.(2) The fact that a buyer has set up a breach of warranty in diminution or extinction of the price does not prevent him from suing for the same breach of warranty if he has suffered further damage.
