29 CFR 102.105 : Labor (§ 0.735-1 To Parts 4908-4999) — (§ 100.101 To Parts 472-499) — Regulations Relating To Labor (§ 100.101 To Parts 472-499) — National Labor Relations Board (§ 100.101 To Parts 105-199) — Rules And Regulations, Series 8 (§ 102.1 To Appendix A To Part 102) — Declaratory Orders And Advisory Opinions Regarding Board Jurisdiction (§ 102.98 To § 102.110) — Petitions for declaratory orders; who may file; where to file; withdrawal.

Whenever both an unfair labor practice charge and a representation case relating to the same employer are contemporaneously on file in a regional office of the Board, and the general counsel entertains doubt whether the Board would assert jurisdiction over the employer involved, he may file a petition with the Board for a declaratory order disposing of the jurisdictional issue in the cases. Such petition may be withdrawn at any time prior to the issuance of the Board's order.
