same as for testimony in a Circuit Court. Witness fees, mileage, and
the actual expenses necessarily incurred in securing attendance of
witnesses and their testimony shall be itemized, and shall be paid

witness was subpoenaed, or by the person, if other than the Com-
missioner, at whose request the hearing is held.

same manner as if issued from a Circuit Court. If any individual
fails to obey a subpoena lawfully served, the Commissioner shall
forthwith report such disobedience, together with a copy of the sub-
poena and proof of service thereof, to the Baltimore City Court or
the Circuit Court for the County in which the individual was re-
quired to appear, and such court shall forthwith cause such indi-
vidual to be produced and shall impose penalties as though he had
disobeyed a subpoena issued out of such court.

(4)   Any person wilfully testifying falsely under oath as to any
matter material to any such examination, investigation, or hearing,
shall upon conviction thereof be guilty of perjury and shall be
punished accordingly.

records, documents or other evidence requested by the Commis-
sioner, or who wilfully fails to give the Commissioner full and
truthful information and answer in writing to any material written
inquiry of the Commissioner, relative to the subject of any such
examination, investigation, or hearing, or wilfully fails to appear
and testify under oath before the Commissioner, shall upon convic-
tion thereof, in addition to or in lieu of any other penalty or penal-
ties applicable, be deemed guilty of a misdemeanor, and upon con-
viction thereof shall be punished by a fine of not more than
$1,000.00 or imprisonment for not more than six months, or both.

28.    Testimony Compelled; Immunity from Prosecution.

No person shall be excused from attending and testifying or pro-
ducing any evidence upon any examination, investigation, or hearing
conducted by or under authority of the Commissioner, on the ground
that his testimony or the evidence required of him may tend to in-
criminate him or subject him to a penalty or forfeiture. No person
shall be prosecuted or punished in any criminal action or proceeding
for or on account of any act, transaction, matter or thing concerning
which he is so compelled to produce evidence or to testify under oath,
except for perjury committed in such testimony.
