The purchaser's right to the warranty shall be established even if they, acting in good faith, acknowledge the third party's right or conclude a settlement with them in respect thereof without awaiting a judicial ruling to be issued, provided that the purchaser had notified the seller of the claim in due time and called upon them to substitute for them therein, and the seller failed to do so.
