Authorising an Advocate to accompany summoned persons restricts communication during examination and mandates prior written authorisation. An Advocate may accompany a person summoned by the Director General only if a written request and an authorisation letter or vakalatnama are submitted beforehand; the Advocate must not sit in front of the summoned person, must remain beyond hearing distance, and must not interact, consult, confer or otherwise communicate with the person during that person's examination on oath.
