5 CFR § 2422.14 - What is the effect of your withdrawal or the Regional Director's dismissal of a petition?
(a) Withdrawal/dismissal less than sixty (60) days before contract expiration.
(1) If you withdraw a timely filed petition seeking an election, or the Regional Director dismisses the petition less than sixty (60) days before the existing agreement between the incumbent exclusive representative and the agency or activity expires, or any time after the agreement expires, another petition that seeks an election will not be considered timely if filed within a ninety (90) day period beginning with either:
(i) The date on which the Regional Director approves the withdrawal; or
(ii) The date on which the Regional Director dismisses the petition when the Authority does not receive an application for review; or
(iii) The date on which the Authority rules on an application for review.
(2) Other pending petitions that have been timely filed under this part will continue to be processed.
(b) Withdrawal by petitioner. If you submit a withdrawal request for a petition seeking an election that the Regional Director receives after the notice of hearing issues or after approval of an election agreement, whichever occurs first, you will be barred from filing another petition seeking an election for the same unit or any subdivision of the unit for six (6) months from the date on which the Regional Director approves the withdrawal.
(c) Withdrawal by incumbent. When an election is not held because the incumbent disclaims any representation interest in a unit, an incumbent's petition seeking an election involving the same unit or a subdivision of the same unit will be considered untimely if filed within six (6) months of cancellation of the election.
