(a) At any time after 30 days after issuance of a complaint, or after publication of notice of an adjudicative hearing in a rulemaking proceeding under §3.13, any party may serve on any other party a written request for admission of the truth of any matters relevant to the pending proceeding set forth in the request that relate to statements or opinions of fact or of the application of law to fact, including the genuineness of any documents described in the request. Copies of documents shall be served with the request unless they have been or are otherwise furnished or are known to be, and in the request are stated as being, in the possession of the other party. Each matter of which an admission is requested shall be separately set forth.

(b) The matter is admitted unless, within 10 days after service of the request, or within such shorter or longer time as the Administrative Law Judge may allow, the party to whom the request is directed serves upon the party requesting the admission a sworn written answer or objection addressed to the matter. If objection is made, the reasons therefor shall be stated. The answer shall specifically deny the matter or set forth in detail the reasons why the answering party cannot truthfully admit or deny the matter. A denial shall fairly meet the substance of the requested admission, and when good faith requires that a party qualify its answer or deny only a part of the matter of which an admission is requested, the party shall specify so much of it as is true and qualify or deny the remainder. An answering party may not give lack of information or knowledge as a reason for failure to admit or deny unless the party states that it has made reasonable inquiry and that the information known to or readily obtainable by the party is insufficient to enable it to admit or deny. A party who considers that a matter of which an admission has been requested presents a genuine issue for trial may not, on that ground alone, object to the request; the party may deny the matter or set forth reasons why the party cannot admit or deny it.

(c) Any matter admitted under this rule is conclusively established unless the Administrative Law Judge on motion permits withdrawal or amendment of the admission. The Administrative Law Judge may permit withdrawal or amendment when the presentation of the merits of the proceeding will be subserved thereby and the party who obtained the admission fails to satisfy the Administrative Law Judge that withdrawal or amendment will prejudice him in maintaining his action or defense on the merits. Any admission made by a party under this rule is for the purpose of the pending proceeding only and is not an admission by him for any other purpose nor may it be used against him in any other proceeding.
