Exceptions—who may file; time limits for filing, including determining date of service of arbitration award for the purpose of calculating time limits; procedural and other requirements for filing.
5 C.F.R. § 2425.2
in effectEffective: 2024-07-01(a) Who may file. Either party to arbitration under the provisions of chapter 71 of title 5 of the United States Code may file an exception to an arbitrator's award rendered pursuant to the arbitration.
(b) Timeliness requirements—general. The time limit for filing an exception to an arbitration award is thirty (30) days after the date of service of the award. This thirty (30)-day time limit may not be extended or waived. In computing the thirty (30)-day period, the first day counted is the day after, not the day of, service of the arbitration award. Example: If an award is served on May 1, then May 2 is counted as day 1, and May 31 is day 30; an exception filed on May 31 would be timely, and an exception filed on June 1 would be untimely. In order to determine the date of service of the award, see the rules set forth in subsection (c) of this section, and for additional rules regarding computing the filing date, see 5 CFR 2429.21 and 2429.22.
(c) Methods of service of arbitration award; determining date of service of arbitration award for purposes of calculating time limits for exceptions. If the parties have reached an agreement as to what is an appropriate method(s) of service of the arbitration award, then that agreement—whether expressed in a collective bargaining agreement or otherwise—is controlling for purposes of calculating the time limit for filing exceptions. If the parties have not reached such an agreement, then the arbitrator may use any commonly used method—including, but not limited to, electronic mail (hereinafter “e-mail”), facsimile transmission (hereinafter “fax”), regular mail, commercial delivery, or personal delivery—and the arbitrator's selected method is controlling for purposes of calculating the time limit for filing exceptions. The following rules apply to determine the date of service for purposes of calculating the time limits for filing exceptions, and assume that the method(s) of service discussed are either consistent with the parties' agreement or chosen by the arbitrator absent such an agreement:
(1) If the award is served by regular mail, then the date of service is the postmark date or, if there is no legible postmark, then the date of the award; for awards served by regular mail, the excepting party will receive an additional five days for filing the exceptions under 5 CFR 2429.22.
(2) If the award is served by commercial delivery, then the date of service is the date on which the award was deposited with the commercial delivery service or, if that date is not indicated, then the date of the award; for awards served by commercial delivery, the excepting party will receive an additional five days for filing the exceptions under 5 CFR 2429.22.
(3) If the award is served by e-mail or fax, then the date of service is the date of transmission, and the excepting party will not receive an additional five days for filing the exceptions.
(4) If the award is served by personal delivery, then the date of personal delivery is the date of service, and the excepting party will not receive an additional five days for filing the exceptions.
(5) If the award is served by more than one method, then the first method of service is controlling when determining the date of service for purposes of calculating the time limits for filing exceptions. However, if the award is served by e-mail, fax, or personal delivery on one day, and by mail or commercial delivery on the same day, the excepting party will not receive an additional five days for filing the exceptions, even if the award was postmarked or deposited with the commercial delivery service before the e-mail or fax was transmitted.
(d) Procedural and other requirements for filing. Exceptions must comply with the requirements set forth in 5 CFR 2429.24 (Place and method of filing; acknowledgment), 2429.25 (Number of copies and paper size), 2429.27 (Service; statement of service), and 2429.29 (Content of filings).
