—Effect of Admission

the merits of (a) Any matter admitted under this section is con- clusively established unless the judicial authority on motion permits withdrawal or amendment of the admission. The judicial authority may permit withdrawal or amendment when the presentation of the action will be subserved thereby and the party who obtained the admission fails to satisfy the judicial authority that withdrawal or amendment will prejudice such party in main- taining his or her action or defense on the merits. Any admission made by a party under this section is for the purpose of the pending action only and is not an admission by him or her for any other purpose nor may it be used against him or her in any other proceeding. (b) The admission of any matter under this sec- tion shall not be deemed to waive any objections to its competency or relevancy. An admission of the existence and due execution of a document, unless otherwise expressed, shall be deemed to include an admission of its delivery, and that it has not since been altered.
