call and give evidence and make submissions to a tribunal on any matter arising during the hearing of the claim;
file affidavits, statements or other documents;
agree to an adjournment or change of venue;
agree to a settlement of the claim on such terms as he thinks fit;
amend or abandon the claim; and
act generally in as full and free a manner as such claimant may act on his own behalf.
(4) The authority deemed to be given to a representative by subsection (3) shall not be withdrawn except by leave of the tribunal.
(5) A tribunal may, at any time before determining any claim, grant leave to any person to join in the claim as a person represented on such terms as it may think fit.
