LEGAL PRINCIPLE: An independent contractor is one who is employed to do some work of his employer. He is engaged under contract for services. He undertakes to produce a given result, and in the actual execution of the work, he is not under the direct control or following directions of his employer. He may use his own discretion in execution of the work assigned.
In general, an employer is not liable for the torts (wrongful acts) of his independent contractor. But, the employer may be held liable if he directs him to do some careless acts.
