What is the extent of liability of the master?

The law is settled that a master is vicariously liable for the acts of his servants acting in the course of employment. Unless the act is done in the course of employment, the servant’s act does not make the employer liable. In other words, for the master’s liability to arise, the act must be a wrongful act authorized by the master. If a servant, at time of the accident, is not acting within the course of employment but is doing something for himself, the master is not liable.
