Code of Civil Procedure Article 280

A fact shall be deemed admitted where a party does not dispute a fact alleged by the opposing party in oral argument, except where a party has already made other statements which may be considered to dispute such fact.Where a party states that he/she has no knowledge or memory with regard to a fact alleged by the opposing party, the court shall, taking all circumstances into consideration, determine whether such statement constitutes an admission.The first paragraph shall apply mutatis mutandis to cases where a party who has been timely and legally notified of a fact alleged by the opposing party neither appears in the oral-argument sessions nor submits a preparatory pleading to dispute such fact, except where the party failing to appear is notified by constructive notice.
