Sir(s),
If the staff member died due to only illness, then the case cannot be called as 'employment injury' under Employees' State Insurance Act, 1948. if the employer has submitted accident report to the appropriate branch office manager of ESIC and if the case is admitted as that of employment injury by appropriate Branch Office, only then the question will arise for payment of dependant's benefit to the dependants of the insured person (staff member).
Under ESI Act, 1948 there is no provision of any lump-sum payment of dependants benefit. The amount of dependant's benefit has no relation with the age of the deceased insured person. The said dependant benefit is paid monthly to the eligible dependants as defined in said Act.
The daily rate of dependant's benefit is 90% of the standard benefit rate in the contribution period corresponding to the benefit period in which employment injury occurs. Kindly see Rule 58 of ESI (Central) Rules, 1950.
With regards;
