This petition under Section 34 of the Arbitration and Conciliation Act, 1996 was filed by HDFC Ergo General Insurance Company Ltd. challenging an arbitral award that had granted National Aluminium Company Limited (NACL) ₹4,25,66,183/- for damage caused by a fire in a generator transformer. The primary controversy centered on whether a proportional deduction for “under-insurance” (assessed at 56.53% by the surveyor) should have been applied. The Delhi High Court held that the majority members of the arbitral tribunal committed patent illegality by ignoring Clause 10 of the General Conditions of the policy and statutory principles, as NACL had paid premiums on a much lower sum insured compared to the actual reinstatement value. Consequently, the Court set aside the majority arbitral award.
- Factual Background: NACL held a Standard Fire and Special Perils Insurance Policy with HDFC Ergo for its power plant in Odisha. A fire broke out in Generator Transformer Unit-08 (GT-8). Following repairs and assessments, NACL claimed over ₹95 crores. The surveyor assessed the actual loss but noted a major “under-insurance” of 56.53% since the plant’s total value was ₹54,000,000,000/-, while the sum insured was only ₹23,473,242,000/-.
- Tribunal’s Majority Award: The majority of the arbitral tribunal accepted the surveyor’s calculation regarding the plant’s true value and the existence of under-insurance, yet inexplicably failed to apply the pro-rata averaging out formula to scale down the claim, awarding the full repair amount instead.
- Legal Principles of Under-Insurance: Referencing Supreme Court precedents like Sikka Papers Limited v. National Insurance Company Ltd. and C. Sharma v. Oriental Insurance Company Limited, the High Court reiterated that where property is partially damaged and under-insured, the principle of “averaging out” must apply because the insured has paid a lower premium relative to the property’s actual value.
- Patent Illegality and Final Ruling: The High Court found that the majority award went beyond the terms of Clause 10 of the General Conditions (which mandates that an under-insured party acts as its own insurer for the difference) and violated Section 64VB of the Insurance Act, 1938. Holding the award to be patently illegal, the Court allowed HDFC Ergo’s petition and set aside the award.
