No testimony taken under authority of R.S. 51:143 shall be made public, unless by order of the governor, for the use in proper judicial proceedings.
Any person giving unlawful publicity to the testimony shall be in contempt of the court issuing the original order, and shall be fined not less than fifty dollars nor more than two thousand dollars or imprisoned not less than five days nor more than six months, or both. Any and all testimony taken under authority of R.S. 51:143 shall be heard only in the presence of the interested parties and their attorneys, but may be introduced in evidence in subsequent proceedings by the state against the person investigated, unless, in the discretion of the trial court, the defense would be unfairly affected.
