Sir(s),
I may like to take part in this discussion and submit as follows:-
(1) Section 53 of Employees' State Insurance Act, 1948 debars only the Insured Persons or their dependants as covered under the said Act to claim compensation under Employees' Compensation Act, 1923 from the employers. It does not exclude the operation of Employees' Compensation Act, 1923 totally from any establishment/factory, which are also covered under Employees' State Insurance Act, 1948.
(2) However, the definition of "employee" as mentioned in Section 2(1)(dd) of Employees Compensation Act, 1923 alongwith Schedule-II of the same is a long list of occupations, which includes factories/establishments defined as "factories" or "mines" in respective Acts.
Therefore, in my opinion, all employees working in occupations as defined in section 2(1)dd & Schedule -II of the Employees' Compensation Act, 1923 are entitled for compensation under EC Act, as mentioned above (except insured persons and their dependants who are covered under Employees' State Insurance Act, 1948).
Further under Employees' Compensation Act, 1923, I have not found any wage ceiling restricting coverage of a particular set of employees getting wages only upto some wage ceiling. If I am not wrong, the employees getting wages exceeding to Rs. 15000/- per month ( not covered under ESI Act,1948) are coverable under Employees' Compensation Act, 1923, if otherwise defined as an "employee" under said Act.
Further the coverage under Employees' State Insurance Act, 1948 is restricted only to implemented areas and to employees getting wages upto coverable wage limit (presently Rs.15000/- per month), whereas the provisions of Employees' Compensation Act, 1923 (as mentioned above) extends to whole of India.
Perhaps, members will correct me if I am wrong in any way.
With regards;
