12. Despite anything in the Rules of Court (Cap. 322, R 5), proceedings before a tribunal are to be conducted in an informal manner, and a tribunal may, in such proceedings —
(a)
give such directions for the proceedings as the tribunal thinks fit;
(b)
conduct the proceedings in such manner as the tribunal thinks fit;
(c)
enquire into any matter which the tribunal may consider relevant to the proceedings (whether or not such matter has been raised by a party); and
(d)
where any party does not appear at a hearing in the proceedings, proceed with the hearing in the absence of that party and make such orders as the tribunal thinks fit.
