Understanding Employer Liability for On-Duty Injuries: Which Laws Apply?

I am looking to understand how an employer would be deemed responsible for medical treatment expenses/compensation of an injured employee who met with an accident during duty hours. Please help me with which Acts and Sections I can refer to with respect to this matter.

Please note that mere duty hours would not be considered as criteria.

Please check the establishment's ESIC or medical insurance policy. If the establishment is industrial, then all rules come into force when the establishment employs 10 or more male workers working with power or 20 or more without power.

I would request you first to go through the Employees' Compensation Act, 1923.

In this connection, you may also refer to the many threads containing answers on various queries relating to employment accidents, the liability of the employer for medical expenses for the injuries sustained by the employee, compensation for the resultant physical disability, and the settlement of claims under the provisions of the said Act on citehr.com itself.
