Answer ... Neither the Arbitration and Conciliation Act nor the Lagos State Arbitration Law provides for instances or circumstances in which a party can apply to the courts of the seat for a ruling on the jurisdiction of the tribunal. However, Section 34 of the Arbitration and Conciliation Act states that a court will not intervene in any matter governed by the act, except where so provided in the act. Also, given that the tribunal can rule on its own jurisdiction, a party can bring an application asking that the court stay any proceedings in which it has been asked to rule on the jurisdiction of the tribunal.
