the employer which gives ingress or egress to the factory is a limited one, in the case of a city transport service, by analogy, the entire fleet of buses forming the service would be the "premises". An illustration may make our point clear. Suppose, in view of the long distances to be covered by the employees, the Corporation, as a condition of service, provides a bus for collecting all the drivers from their houses so that they may reach their depots in time and to take them back after the day's work so that after the heavy work till about 7 p.m. they may reach their homes without further strain on their health. Can it be said that the said facility is not one given in the course of employment? It can even be said that it is the duty of the employees in the interest of the service to utilise the said bus both for coming to the depot and going back to their homes. If that be so, what difference would it make if the employer, instead of providing a separate bus, throws open his entire fleet of buses for giving the employees the said facility? They are given that facility not as members of the public but as employees; not as a grace but as of right because efficiency of the service demands it. We would, therefore, hold that when a driver when going home from the depot or coming to the depot uses the bus, any accident that happens to him is an accident in the course of his employment.”
