Death by Mosquito Bite Not an Accident: Supreme Court Rules on Insurance Claim

The Supreme Court of India recently ruled on an important case involving insurance claims for accidental death. The case, The Branch Manager, National Insurance Co. Ltd. vs. Smt. Mousumi Bhattacharjee & Ors., centered around whether a death caused by malaria, contracted from a mosquito bite in Mozambique, qualified as an ‘accidental death’ under a personal accident insurance policy.

This judgment is crucial in interpreting insurance contracts and determining what constitutes an accident under such policies.

Background of the Case

The case arose from a claim made by the family of Debashis Bhattacharjee, who had taken a home loan from the Bank of Baroda in 2011. Along with the loan, he availed of an insurance policy called ‘National Insurance Home Loan Suraksha Bima,’ which included coverage for accidental death.

Bhattacharjee, who was working in Mozambique, contracted malaria and died of multi-organ failure on 22 November 2012. His family filed an insurance claim under the policy, which the insurer rejected, arguing that death due to malaria was not an ‘accident’ under the policy’s terms.

The family approached the District Consumer Disputes Redressal Forum, which ruled in their favor. The insurer then appealed to the State Consumer Disputes Redressal Commission and later the National Consumer Disputes Redressal Commission (NCDRC), both of which upheld the decision. The insurer then appealed to the Supreme Court.

Petitioner’s Arguments

The appellant, National Insurance Co. Ltd., put forth the following arguments:

  • The insurance policy explicitly covered death due to ‘accident’ and not due to disease or natural causes.
  • Malaria is a common occurrence in tropical countries like Mozambique and cannot be considered an ‘accident.’
  • The term ‘accident’ denotes an unforeseen, unexpected event, whereas contracting malaria is a natural consequence of residing in a high-risk area.
  • The insured had not informed the insurer about his change in occupation and relocation to Mozambique, which was a breach of the policy’s terms.

Respondent’s Arguments

The family of the deceased countered with the following points:

  • A mosquito bite is an unforeseen event, making it an accident.
  • The insurance policy did not explicitly exclude death due to disease resulting from an insect bite.
  • The insurer had failed to provide a clear definition of ‘accident’ in the policy, and therefore, the common understanding of the term should apply.
  • The lower consumer courts had already ruled in their favor, and there was no basis for reversing the decision.

Supreme Court’s Observations

The Supreme Court thoroughly examined the issue, analyzing various precedents and legal definitions of the term ‘accident.’

The Court noted:

“An accident is an occurrence which is unnatural, unforeseen, or unexpected. A disease caused due to the natural course of human events does not qualify as an accident. Malaria in Mozambique is a common risk, with nearly one-third of the population affected. Hence, contracting malaria cannot be considered accidental.”

The Court also examined international legal definitions and insurance principles, citing various legal dictionaries and past judgments to reinforce that accidents must be distinguished from diseases caused by natural factors.

Final Judgment

The Supreme Court ruled as follows:

  • The claim for accidental death under the insurance policy was not justified.
  • The judgment of the NCDRC was set aside.
  • However, since the insurance amount had already been paid, the Court directed that no recovery be made from the family of the deceased.

The Court concluded:

“While the loss of life due to malaria is unfortunate, it does not qualify as an accident under the terms of the insurance policy. The insurer cannot be held liable for a risk that was not explicitly covered under the contract.”

Implications of the Verdict

This ruling has significant implications for the insurance industry and policyholders:

  • Clarification on Accidental Death: The judgment establishes that contracting a disease, even from an external source like a mosquito bite, does not amount to an accident.
  • Importance of Policy Interpretation: Insurers must clearly define policy terms to avoid disputes over coverage.
  • Policyholder Awareness: Buyers of insurance must understand what their policies cover and disclose material facts about their residence and occupation.
  • Consumer Protection Limitations: While consumer courts tend to rule in favor of policyholders, the Supreme Court has reinforced the need to adhere to contract terms.

By reinforcing the fundamental principles of insurance law, this ruling ensures that claims are evaluated strictly within the framework of contractual obligations and legal definitions.
