A person who, in answer to a witness summons, is attending an examination or otherwise attending the Director is guilty of a contempt of the Director if the person—
(a) fails without reasonable excuse to produce any document or other thing the person is required by the summons to produce; or
(b) being called or examined as a witness, refuses to be sworn or to make an affirmation or, without reasonable excuse, refuses or fails to answer any question relevant to the subject-matter of the investigation; or
(c) engages in any other conduct that would, if the Director were the Supreme Court, constitute a contempt of that Court.
