Answer ... A party should raise an objection to jurisdiction of the tribunal in its statement of defence at the latest, but in any case before entering into a dispute on the merits.

Answer ... The arbitral tribunal may rule on its own jurisdiction, including on the existence, validity or effectiveness of the arbitration agreement.

Answer ... If the arbitral tribunal dismisses the objection, either party may, within two weeks of being served with the decision, seek a ruling from a court on the issue. The initiation of court proceedings does not stay the arbitration. The court’s decision may be appealed.
