general jurisdiction in the city or county in which the hearing is
held.

(b)  If any person refuses, without valid cause, when ordered by
the commission, any commissioner or the secretary of the commis-
sion, to attend, or by the commission, any commissioner or any
authorized hearing examiner to give any relevant testimony or to
produce any relevant evidence, the commission or any commissioner
may apply, upon affidavit setting forth such fact to any judge of
a court of general jurisdiction for a rule or order returnable in not
less than two nor more than five days, to show cause why such
person should not be committed to jail. Upon the return of such
order, if the judge hearing the matter determines that the said
person has been guilty of such refusal, and persists therein, he may
forthwith commit the offender to jail as in cases of contempt.

(c)  No person shall be excused from giving testimony or produc-
ing evidence before the commission, upon proper order to do so,
upon the ground that such testimony or evidence may tend to in-
criminate him or subject him to penalty or forfeiture; but no per-
son shall be prosecuted, punished or subjected to penalty or forfei-
ture (except in case of perjury committed by him in giving evidence
before the commission) for or on account of anything concerning
which he gave evidence required by such order. The immunity con-
ferred by this subsection shall extend only to natural persons and
not to corporations.

Maryland, in accordance with the procedure provided by law or rule
of court with respect to actions at law, subject to regulation by the
commission to prevent undue delays.

(d)   The right to require that the commissioners responsible for
final decision personally consider the record in the case, or such
portions thereof as may be cited by the parties.
