Case Note & Summary
The case involves an arbitration petition filed by the Municipal Corporation of Greater Mumbai (Petitioner) challenging an arbitral award passed by a sole arbitrator in favor of S.N. Thakkar Construction Company Private Limited (Respondent). The dispute arose out of a construction contract for diversion chambers for sewage diversion 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. The Respondent submitted a bar chart and cash flow statement after the due date. During the work, the Petitioner complained of slow progress and breaches. The contract ended by efflux of time on 31.05.2004. The Respondent applied for extension of time and later raised claims for wrongful termination and other losses. The arbitrator awarded various sums to the Respondent, including interest at 18% per annum on the principal amount from the date of the award until payment. The Petitioner challenged the award primarily on the ground that the interest rate was excessive and contrary to the contract, which stipulated interest at 12% per annum for delayed payments. The court analyzed the contractual provisions and found that the contract clearly provided for interest at 12% per annum on delayed payments. The court held that the arbitrator's award of 18% interest was not in accordance with the contract and amounted to a patent illegality under Section 34 of the Arbitration and Conciliation Act, 1996. The court modified the award by reducing the interest rate to 12% per annum from the date of the award until payment, while upholding the rest of the award. The petition was partly allowed.
