Answer ... Article 16(2) of Schedule 1 to the act requires a party seeking to challenge the jurisdiction of the tribunal to do so no later than the submission of the statement of defence.
Insofar as the objection relates to conduct of the tribunal which exceeds the scope of authority, this is to be raised as soon as the matter alleged to be beyond the scope of the tribunal’s powers is raised in the proceedings.
The tribunal may admit a later plea (of lack of jurisdiction) if it considers the delay justified. No formalities are prescribed for the raising of such an objection.
Answer ... Yes, in accordance with Article 16(1) of Schedule 1 to the act, the tribunal may rule on its own jurisdiction.

The decision of the court is not subject to appeal.
