5 CFR § 1201.26 - Service of pleadings and response.
(a) Service—(1) Service by the Board. The appropriate office of the Board will notify each party to the proceeding that a new appeal has been docketed and will attach to the initial order in the proceeding a certificate of service, consisting of a list of the parties to the proceeding or their designated representatives.
(2) Service by the parties. The parties must serve on each other one copy of each pleading, as defined by § 1201.4(b), and all documents submitted with it, except for the appeal. They may do so by electronic filing in accordance with § 1201.14, postal mail, facsimile, or commercial or personal delivery. Documents and pleadings must be served on each party and each representative. A certificate of service stating how and when service was made must accompany each pleading. The parties and their representatives must notify the appropriate Board office and one another, in a pleading, of any changes in their address, telephone number, or email address.
(b) Submission of documents. Pleadings and attachments filed via postal mail, facsimile, or commercial or personal delivery must be filed on 8 1/2-inch by 11-inch paper. This requirement enables the Board to comply with standards established for U.S. courts. Paper pleadings and attachments may not contain binders, folders, staples, paper clips, or notes adhered to pages. Such items will be removed and not included in the record, or the filing may be rejected. Documents may not be submitted on an electronic media storage device such as a Compact Disc (CD), Digital Video Disc (DVD), or flash drive. Parties are responsible for reviewing all pleadings to confirm legibility and to minimize the inclusion of nonrelevant personally identifiable information. Pleadings filed via e-Appeal must adhere to the formatting and filing requirements set forth in § 1201.14(h).
(c) Submission of audio and video evidence. Audio and video evidence must be submitted according to the formatting and submission requirements set forth in policies posted to the MSPB's website.
