102.105—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 Such petition may be withdrawn at any time prior to the issuance of the Board's order.
