Rules of practice and procedure

The commission shall prescribe rules of practice and procedure, the method and manner of holding hearings, and for taking evidence on all matters that may come before it, and enter such orders as may be just and lawful. In the investigations, preparations, and hearings of cases, the commission shall not be bound by the technical rules of pleadings and evidence, but in that respect it may exercise such discretion as will facilitate its efforts to understand and learn all the facts bearing upon the right and justness of the matter before it.#
