221.Section 69 allows Tribunal Rules to make provision about how a function of the Tribunals is to be exercised and by whom, or allow a specified person to make a decision about those matters. It also allows Tribunal Rules to confer functions on the persons named in subsection (4). Such Rules may provide for something to require further authorisation, allow something to be done on a person’s behalf, or allow a specified person to make a decision about those matters. They may rely on the effect of practice directions issued under section 74.
