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 and such person shall come on for a hearing 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, with
out reasonable cause or legal excuse, to be examined or to answer a legal
or 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 was so required to do, or is
discharged according to law.

No person shall be excused from testifying or from producing any books
or papers or documents in any investigation or inquiry by or upon any
hearing before the Commission or any Commissioner, when ordered to do
so by the Commission or its Secretary, upon the ground that the testi-
mony or evidence, books, papers, 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 forfeiture
for or on account of any act, transaction, matter or thing concerning which
he shall, under oath, have, by order of the Commission or a Commissioner
or its inspector or examiner, testified to or produced documentary evidence
of; provided, however, that no person so testifying shall be exempt from
prosecution or punishment for any perjury committed by him in his testi-
mony.

the Commission or an inspector or an examiner, shall receive for his at-
tendance the fees and mileage provided for witnesses in civil cases in the
Circuit Courts of the Counties or the Common Law Courts of Baltimore
City, as of the place where he gives his testimony, which shall be audited
and paid from the State Treasury in the same manner as other vouchers
approved by any member of the Commission and the Secretary. No wit-
ness subpoenaed at the instance of a party other than the Commission, or an
inspector or examiner, shall be entitled to compensation from the State
Treasury unless the Commission shall certify that his testimony was ma-
terial to the matter investigated. In an investigation, the Commission may
cause depositions of witnesses residing within or without the State to b'e
taken in the manner prescribed by law for like depositions taken in cases
pending before the Circuit Courts of the Counties or the Common Law
Courts of Baltimore City, as is now or hereafter may be provided by law.
