29 CFR § 2700.9 - Extensions of time.
(a) The time for filing or serving any document may be extended for good cause shown. Filing of a motion requesting an extension of time is effective upon receipt. A motion requesting an extension of time shall be received no later than 3 days prior to the expiration of the time allowed for the filing or serving of the document, and shall comply with § 2700.10. The motion and any statement in opposition shall include proof of service on all parties by a means of delivery no less expeditious than that used for filing the motion, except that if service by electronic transmission (email) is impossible, the filing party must serve in person, by third party commercial carrier, or by facsimile transmission, resulting in same-day delivery.
(b) In exigent circumstances, an extension of time may be granted even though the request was filed after the designated time for filing has expired. In such circumstances, the party requesting the extension must show, in writing, the reasons for the party's failure to make the request before the time prescribed for the filing had expired.
(c) This rule does not apply to petitions for discretionary review filed pursuant to section 113(d)(2)(A)(i) of the Act, 30 U.S.C. 823(d)(2)(A)(i), and § 2700.70(a).
