§ 804. Reports; confidential information. A board of inquiry shall, after investigation, make a final report to the commissioner as to the matters referred to it and may make interim reports. Unless the strike, lock-out or other industrial dispute is terminated or adjusted prior thereto, or is re-submitted by all parties to the dispute for voluntary settlement to the state board of mediation, any final report of a board of inquiry shall be made public by the commissioner. The commissioner may make public any interim report of a board of inquiry or any part thereof, in such manner as he deems proper. Provided, however, that there shall be excluded from any report or publication authorized by the board or the commissioner, any information, other than information having a direct bearing on the dispute, obtained by the board in the course of its inquiry as to any labor union or as to any individual business (whether carried on by person, firm or corporation) if at the time such information is supplied to the board the person who supplies it represents to the board that it is confidential information and the board is satisfied that it is information which is not available otherwise than through evidence given at the inquiry, unless with respect to such evidence so presented as confidential and found to be not otherwise available the board procures from the labor union or the person, firm or corporation the consent to publication; nor shall any individual member of the board or any person concerned in the inquiry, without such consent, disclose any such information.
