5 CFR § 1201.29 - Dismissal without prejudice.
(a) In general. Dismissal without prejudice is a procedural option that allows for the dismissal and subsequent refiling of an appeal.
(b) Procedure. Dismissal without prejudice may be granted on the judge's own motion or upon request by either party. The decision whether to dismiss an appeal without prejudice is committed to the sound discretion of the judge, and may be granted when the interests of fairness, due process, and administrative efficiency outweigh any prejudice to either party.
(c) Refiling. Except in certain USERRA appeals under Part 1208 involving the use of military leave, a decision dismissing an appeal without prejudice will include a date certain by which the appeal must be refiled. The judge will determine whether the appeal must be refiled by the appellant or whether it will be automatically refiled by the judge as of a date certain. When a dismissal without prejudice is issued over the objection of the appellant, the appeal will be automatically refiled as of a date certain.
