Whenever it is charged that any person has engaged in an unfair labor practice within the meaning of Section 8(b)(4)(D) of the Act, the Regional Director of the office in which such charge is filed or to which it is referred will, as soon as possible after the charge has been filed, serve on the parties a copy of the charge and will investigate such charge and if it is deemed appropriate to seek injunctive relief of a district court pursuant to Section 10(l) of the Act, the Regional Director will give it priority over all other cases in the office except other cases under Section 10(l) and cases of like character.

If it appears to the Regional Director that the charge has merit and the parties to the dispute have not submitted satisfactory evidence to the Regional Director that they have adjusted, or have agreed-upon methods for the voluntary adjustment of, the dispute out of which such unfair labor practice has arisen, the Regional Director will serve on all parties to such dispute a Notice of Hearing under Section 10(k) of the Act before a Hearing Officer at a time and place stated in the Notice. The hearing date will not be less than 10 days after service of the notice of the filing of the charge. The Notice of Hearing must contain a simple statement of the issues involved in such dispute. Such Notice will be issued promptly, and, in cases in which it is deemed appropriate to seek injunctive relief pursuant to Section 10(l) of the Act, will normally be issued within 5 days of the date upon which injunctive relief is first sought. Hearings will be conducted by a Hearing Officer, and the procedure will conform, insofar as applicable, to the procedure set forth in §§ 102.64 through 102.68. Upon the close of the hearing, the proceeding will be transferred to the Board, and the Board will proceed either promptly upon the record, or after oral argument, or the submission of briefs, or further hearing, to determine the dispute or otherwise dispose of the matter. Parties who desire to file a brief with the Board must do so within 7 days after the close of the hearing. However, no briefs will be filed in cases designated in the Notice of Hearing as involving the national defense, and the parties, after the close of the evidence, may argue orally upon the record their respective contentions and positions; except that, upon application for leave to file briefs expeditiously made to the Board in Washington, DC, after the close of the hearing, the Board may for good cause shown, grant leave to file briefs and set a time for filing. Simultaneously upon such filing, a copy must be served on the other parties. No reply brief may be filed except upon special leave of the Board.

If, after issuance of the determination by the Board, the parties submit to the Regional Director satisfactory evidence that they have complied with the determination, the Regional Director will dismiss the charge. If no satisfactory evidence of compliance is submitted, the Regional Director will proceed with the charge under Section 8(b)(4)(D) and Section 10 of the Act and the procedure prescribed in §§ 102.9 through 102.51 will, insofar as applicable, govern. However, if the Board determination is that employees represented by a Charged Union are entitled to perform the work in dispute, the Regional Director will dismiss the charge as to that union irrespective of whether the employer has complied with that determination.

The record of the proceeding under Section 10(k) and the determination of the Board will become a part of the record in such unfair labor practice proceeding and may be subject to judicial review in proceedings to enforce or review the final order of the Board under Section 10(e) and (f) of the Act.

If, either before or after service of the Notice of Hearing, the parties submit to the Regional Director satisfactory evidence that they have adjusted the dispute, the Regional Director will dismiss the charge and will withdraw the Notice of Hearing if Notice has issued. If, either before or after issuance of the Notice of Hearing, 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 will defer action upon the charge and will withdraw the Notice of Hearing if Notice has issued. If it appears to the Regional Director that the dispute has not been adjusted in accordance with such agreed-upon methods and that an unfair labor practice within the meaning of Section 8(b)(4)(D) of the Act is occurring or has occurred, the Regional Director may issue a complaint under § 102.15, and the procedure prescribed in §§ 102.9 through 102.51 will, insofar as applicable, govern; and §§ 102.90 through 102.92 are inapplicable, except that if an 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 will dismiss the charge as to that union irrespective of whether the employer has complied with that determination.
