5 C.F.R. § 1201.155

(a) Source and applicability. (1) Under paragraph (d) of 5 U.S.C. 7121, an employee who believes he or she has been subjected to discrimination within the meaning of 5 U.S.C. 2302(b)(1), and who may raise the matter under either a statutory procedure such as 5 U.S.C. 7701 or under a negotiated grievance procedure, must make an election between the two procedures. The election of the negotiated grievance procedure “in no manner prejudices” the employee's right to request Board review of the final decision pursuant to 5 U.S.C. 7702. Subsection (a)(1) of section 7702 provides that, “[n]otwithstanding any other provision of law,” when an employee who has been subjected to an action that is appealable to the Board and who alleges that the action was the result of discrimination within the meaning of 5 U.S.C. 2302(b)(1), the Board will decide both the issue of discrimination and the appealable action in accordance with the Board's appellate procedures under section 7701.

(2) This section does not apply to employees of the Postal Service or to other employees excluded from the coverage of the Federal labor management laws at chapter 71 of title 5, United States Code.

(b) When filed. The appellant's request for Board review must be filed within 35 days after the date of issuance of the decision or, if the appellant shows that he or she received the decision more than 5 days after the date of issuance, within 30 days after the date the appellant received the decision.

(c) Scope of Board review. If the negotiated grievance procedure permits allegations of discrimination, the Board will review only those claims of discrimination that were raised in the negotiated grievance procedure. If the negotiated grievance procedure does not permit allegations of discrimination to be raised, the appellant may raise such claims before the Board.

(d) Contents. The appellant must file the request with the Clerk of the Board, Merit Systems Protection Board, 1615 M Street NW., Washington, DC 20419. The request for review must contain:

(1) A statement of the grounds on which review is requested;

(2) References to evidence of record or rulings related to the issues before the Board;

(3) Arguments in support of the stated grounds that refer specifically to relevant documents and that include relevant citations of authority; and

(4) Legible copies of the final grievance or arbitration decision, the agency decision to take the action, and other relevant documents. Those documents may include a transcript or recording of the hearing.

(e) Development of the record. The Board, in its discretion, may develop the record as to a claim of prohibited discrimination by ordering the parties to submit additional evidence or forwarding the request for review to a judge to conduct a hearing.

(f) Closing of the record. The record will close upon expiration of the period for filing the response to the request for review, or to the brief on intervention, if any, or on any other date the Board sets for this purpose. Once the record closes, no additional evidence or argument will be accepted unless the party submitting it shows that the evidence was not readily available before the record closed.

(g) Petition for enforcement. A petition for enforcement of a final Board decision or order that was issued pursuant to paragraphs (a) through (f) of this section, should be filed with the Office of the Clerk of the Board and should otherwise comply with the requirements set forth in § 1201.182(a).
