The investigation of a jurisdictional dispute under section 10(k) is initiated by the filing of a charge, as described in § 101.2, by any person alleging a violation of paragraph (4)(D) of section 8(b). As soon as possible after a charge has been filed, the Regional Director serves on the parties a copy of the charge together with a notice of the filing of such charge.

These matters are handled as described in §§ 101.4 to 101.7, inclusive. Cases involving violation of paragraph (4)(D) of section 8(b) in which it is deemed appropriate to seek injunctive relief of a district court pursuant to section 10(1) of the Act are given priority over all other cases in the office except other cases under section 10(1) of the Act and cases of like character.

If, after investigation, it appears that the Board should determine the dispute under section 10(k) of the Act, the Regional Director issues a notice of hearing which includes a simple statement of issues involved in the jurisdictional dispute and which is served on all parties to the dispute out of which the unfair labor practice is alleged to have arisen. The hearing is scheduled for not less than 10 days after service of the notice of the filing of the charge, except that in cases involving the national defense, agreement will be sought for scheduling of hearing on less notice. If the parties present to the Regional Director satisfactory evidence that they have adjusted the dispute, the Regional Director withdraws the notice of hearing and either permits the withdrawal of the charge or dismisses the charge. If the parties submit to the Regional Director satisfactory evidence that they have agreed upon methods for the voluntary adjustment of the dispute, the Regional Director shall defer action upon the charge and shall withdraw the notice of hearing if issued. The parties may agree on an arbitrator, a proceeding under section 9(c) of the Act, or any other satisfactory method to resolve the dispute. If the agreed-upon method for voluntary adjustment results in a determination that employees represented by a charged union are entitled to perform the work in dispute, the Regional Director dismisses the charge against that union irrespective of whether the employer complies with that determination.

If the parties have not adjusted the dispute or agreed upon methods of voluntary adjustment, a hearing, usually open to the public, is held before a hearing officer. The hearing is nonadversary in character, and the primary interest of the hearing officer is to insure that the record contains as full a statement of the pertinent facts as may be necessary for a determination of the issues by the Board. All parties are afforded full opportunity to present their respective positions and to produce evidence in support of their contentions. The parties are permitted to argue orally on the record before the hearing officer. At the close of the hearing, the case is transmitted to the Board for decision. The hearing officer prepares an analysis of the issues and the evidence, but makes no recommendations in regard to resolution of the dispute.

The parties have 7 days after the close of the hearing, subject to any extension that may have been granted, to file briefs with the Board and to request oral argument which the Board may or may not grant. However, in cases involving the national defense and so designated in the notice of hearing, the parties may not file briefs but after the close of the evidence may argue orally upon the record their respective contentions and positions, except that for good cause shown in an application expeditiously made to the Board in Washington, DC, after the close of the hearing, the Board may grant leave to file briefs in such time as it shall specify. The Board then considers the evidence taken at the hearing and the hearing officer's analysis together with any briefs that may be filed and the oral argument, if any, and issues its determination or makes other disposition of the matter.

After the issuance of determination by the Board, the Regional Director in the Region in which the proceeding arose communicates with the parties for the purpose of ascertaining their intentions in regard to compliance. Conferences may be held for the purpose of working out details. If satisfied that the parties are complying with the determination, the Regional Director dismisses the charge. If not satisfied that the parties are complying, the Regional Director issues a complaint and notice of hearing, charging violation of section 8(b)(4)(D) of the Act, and the proceeding follows the procedure outlined in §§ 101.8 to 101.15, inclusive. However, if the Board determines that employees represented by a charged union are entitled to perform the work in dispute, the Regional Director dismisses the charge against that union irrespective of whether the employer complies with the determination.
