Case Note & Summary
The case arises from a construction contract between the Municipal Corporation of Greater Mumbai (Petitioner) and S.N. Thakkar Construction Company Private Limited (Respondent) for providing and constructing diversion chambers for diverting sewage from SWD to sewerage system at seven locations in Mumbai. The contract was awarded in 2002, with work to commence on 01.10.2003 and be completed by 31.05.2004. During the work, the Petitioner complained of slow progress and breaches by the Respondent. The contract ended by efflux of time on 31.05.2004. The Respondent applied for extension of time and later raised several claims, including for compensation for delay and interest on mobilisation advance. Disputes were referred to a sole arbitrator, who passed an award in favor of the Respondent on certain claims. The Petitioner challenged the award under Section 34 of the Arbitration and Conciliation Act, 1996. The main legal issues were whether the arbitrator's findings on delay and compensation were perverse, and whether the award of interest on mobilisation advance was contrary to the contract. The Petitioner argued that the arbitrator ignored the contract terms and that the award was patently illegal. The Respondent contended that the findings were based on evidence and were plausible. The Court held that the arbitrator's findings on delay and compensation were plausible and not perverse, but the award of interest on mobilisation advance was contrary to the express terms of the contract, which provided for interest-free mobilisation advance. The Court set aside the award of interest on mobilisation advance but upheld the rest of the award.

B) Contract - Mobilisation Advance - Interest - Contract terms provided for interest-free mobilisation advance, but arbitrator awarded interest on the amount - Court held that this was contrary to the contract and amounted to patent illegality - Held that the award of interest on mobilisation advance is set aside (Paras 15-18). C) Arbitration - Compensation for Delay - Section 34 of the Arbitration and Conciliation Act, 1996 - Arbitrator awarded compensation for delay based on evidence of hindrances caused by the petitioner - Court held that the findings were plausible and not open to interference - Held that the award of compensation for delay is upheld (Paras 10-14).
