A Civil Court examining the validity of an arbitral award under Section 34 of the Act exercises supervisory and not appellate jurisdiction over the awards of an arbitral tribunal. A court can set aside an arbitral award, only if any of the grounds mentioned in Sections 34(2)(a)(i) to (v) or Section 34(2)(b)(i) and (ii), or Section 28(1)(a) or 28(3) read with Section 34(2)(b)(ii) of the Act, are made out. An award adjudicating claims which are `excepted matters’ excluded from the scope of arbitration, would violate Section 34(2)(a)(iv) and 34(2)(b) of the Act. Making an award allowing or granting a claim, contrary to any provision of the contract, would violate Section 34(2)(b)(ii) read with Section 28(3) of the Act.[J.G. Engineers Pvt.
