In Union of India v. Master Construction Company, (2011) 12 SCC 349, it was held as under:
“In our opinion, there is no rule of the absolute kind. In a case where the claimant contends that a discharge voucher or no claim certificate has been obtained by fraud, coercion, duress or undue influence and the other side contests the correctness thereof, the Chief Justice/his designate must look into this aspect to find out at least, prima facie, whether or not the dispute is bona fide and genuine. Where the dispute raised by the claimant with regard to validity of the discharge voucher or no – claim certificate or settlement agreement, prima facie, appears to be lacking in credibility, there may not be a necessity to refer the dispute for arbitration at all.”
From the proposition which has been laid down by the Hon’ble Apex Court, what reveals is that a mere plea of fraud, coercion or undue influence in itself is not enough and the party who alleged is under obligation to prima facie establish the same by placing satisfactory material on record before the Chief Justice or his Designate to exercise power under Section 11(6) of the Arbitration and Conciliation Act, 1996 which has been considered by the Hon’ble Supre Court in New India Assurance Co. Ltd. v. Genus Power Infrastructure Ltd., (2015) 2 SCC 424 as below:
“It is therefore clear that a bald plea of fraud, coercion, duress or undue influence is not enough and the party who sets up a plea, must prima facie establish the same by placing material before the Chief Justice/ his Designate.”
It is true that there cannot be a rule of its kind that mere allegation of discharge voucher or no claim certificate being obtained by fraud/coercion/undue influence practiced by other party in itself is sufficient for appointment of the arbitrator unless the claimant who alleges that execution of the discharge agreement or no claim certificate was obtained on account of fraud/coercion/undue influence practiced by the other party is able to substantiate the same, the correctness thereof may be open for the Chief Justice/his Designate to look into this aspect to find out at least prima facie whether the dispute is bona fide and genuine in taking a decision to invoke Section 11(6) of the Arbitration and Conciliation Act, 1996. United India Assurance Co. Ltd. v. Antique Art Exports Pvt. Ltd., (2019) 5 SCC 362.
