Oaths. The officer presiding at the hearing or such person as he may designate shall have power to administer oaths and issue subpoenas to compel the attendance of witnesses and the production of relevant evidence, including witnesses and documents presented by the parties, and the provisions of the "County and Municipal Investigations Law," N.J.S.A. 2A:67A-1, et seq., shall apply.

Testimony.

The board shall furnish a transcript or duplicate recording in lieu thereof on request to any interested part at his expense. In furnishing a transcript of the proceedings to an interested party at his expense, the board shall not charge such interested party more than the maximum permitted in N.J.S.A. 2A:11-15. Said transcript shall be certified in writing by the transcriber to be accurate.
