returnable in not less than two nor more than five days, directing such
person to show cause before the judge who made the order, or any other
judge aforesaid, why he should not be committed to jail; upon the return
of such order, the judge before whom the matter shall come on for a hear-
ing shall examine under oath such person, and such person shall be given
an opportunity to be heard; and if the judge shall determine that such
person has refused, without reasonable cause or legal excuse, to be examined
or to answer a legal and pertinent question, or to produce a book or paper
which he was ordered to bring or produce, he may forthwith commit the
offender to jail, there to remain until he submits to do the act which he

358. All hearings before the commission or commissioner shall be
governed by rules to be adopted and prescribed by the commission. And
in all investigations, inquiries or hearings the commission, or a commis-
sioner, shall not be bound by the technical rules of evidence. No person
shall be excused from testifying or from producing any books or papers in
any investigation or inquiry by or upon any hearing before the commission
or any commissioner, when ordered to do so by the commission, upon the
ground that the testimony or evidence, books or documents required of him
may tend to incriminate him or subject him to penalty or forfeiture; but
no person shall be prosecuted, punished or subjected to any penalty or for-
feiture for on account of any act, transaction, matter or thing concerning
which he shall, under oath, have, by order of the commission or a com-

that no person so testifying shall be exempt from prosecution or punish-

contained is intended to give, or shall be construed as in any manner giving
unto any corporation immunity of any kind from the law.
