22 C.F.R. § 16.1
(c) Grievance means any act or condition subject to the control of the Foreign Affairs agencies (the Department of State, the Agency for International Development, or the U.S. Information Agency) which is alleged to deprive the grievant of a right or benefit authorized by law or regulation or is otherwise a source of concern or dissatisfaction to the grievant, including, but not limited to the following:
(d) Grievance does not include the following:
(4) Any complaints or appeals for which a specific statutory appeals procedure exists (see appendix A for examples).
A grievance filed under these procedures may be based on matters for which there is a specific statutory appeals procedure which is applicable to the Foreign Service grievant. Should the jurisdiction of the Grievance Board over a specific grievance be placed into question on grounds that the basis of the grievance is not encompassed within the Board's authority (§ 16.1(d)(4) and Appendix A), the Board shall consult with the other statutory body concerned, transmitting the views of the parties concerned before determining whether it has jurisdiction.
