Section 101.10 - Hearings(a) Except in extraordinary situations the hearing is open to the public and usually conducted in the Region where the charge originated. A duly designated administrative law judge presides over the hearing. The Government's case is conducted by an attorney attached to the Board's Regional Office, who has the responsibility of presenting the evidence in support of the complaint. The rules of evidence applicable in the district courts of the United States under the Rules of Civil Procedure adopted by the Supreme Court are, so far as practicable, controlling. Counsel for the General Counsel, all parties to the proceeding, and the administrative law judge have the power to call, examine, and cross-examine witnesses and to introduce evidence into the record. They may also submit briefs, engage in oral argument, and submit proposed findings and conclusions to the administrative law judge. The attendance and testimony of witnesses and the production of evidence material to any matter under investigation may be compelled by subpoena.(b) The functions of all administrative law judges and other Board agents or employees participating in decisions in conformity with section 8 of the Administrative Procedure Act ( 5 U.S.C. 557 ) are conducted in an impartial manner and any such administrative law judge, agent, or employee may at any time withdraw if he or she deems himself or herself disqualified because of bias or prejudice. The Board's attorney has the burden of proof of violations of section 8 of the National Labor Relations Act and section 222(f) of the Telegraph Merger Act. In connection with hearings subject to the provisions of section 7 of the Administrative Procedure Act ( 5 U.S.C. 556 ):(1) No sanction is imposed or rule or order issued except upon consideration of the whole record or such portions thereof as may be cited by any party and as supported by and in accordance with the preponderance of the reliable, probative, and substantial evidence.(2) Every party has the right to present its case or defense by oral or documentary evidence, to submit rebuttal evidence, and to conduct such cross-examination as may be required for a full and true disclosure of the facts.(3) Where any decision rests on official notice of a material fact not appearing in the evidence in the record, any party is on timely request afforded a reasonable opportunity to show the contrary.(4) Subject to the approval of the administrative law judge, all parties to the proceeding voluntarily may enter into a stipulation dispensing with a verbatim written transcript of record of the oral testimony adduced at the hearing and providing for the waiver by the respective parties of their right to file with the Board exceptions to the findings of fact (but not to conclusions of law or recommended orders) in the administrative law judge's decision.
