13.—(1) Without prejudice to section 39(2), the Authority may of its own motion investigate any security services being provided by any person.

(2) For the purposes of such an investigation the Authority—

(a) may by notice in writing require any person who in its opinion is in possession of information, or has any record or thing in the person's possession or under the person's control, that is relevant to the investigation to supply that information, record or thing to the Authority within a period specified in the notice, and

(b) where appropriate, may require the person to attend before it for those purposes within that period.

(3) The person shall be entitled to the same immunities and privileges in relation to compliance with any requirement mentioned in subsection (2) as if the person were a witness before a court.

(4) If the person does not comply or comply fully with the requirement within the specified period, the Authority may apply to the District Court, on notice to the person, for an order requiring the person to comply or comply fully with the requirement within a period to be specified by the Court.

(5) If it appears to the Court, on application by the Authority, that the person has failed, without reasonable excuse (proof of which shall lie on the person), to comply or comply fully with the order, the Court may treat the failure for all purposes as if it were a contempt in the face of the Court.

(6) The jurisdiction conferred on the District Court by this section may be exercised by the judge of that Court for the time being assigned to the district court district in which the person concerned ordinarily resides or carries on any profession, business or occupation.
