Vicarious liability

Vicarious liability is a form of a strict, secondary liability that arises under the common law doctrine of agency, respondeat superior, the responsibility of the superior for the acts of their subordinate or, in a broader sense, the responsibility of any third party that had the "right, ability or duty to control" the activities of a violator. It can be distinguished from contributory liability, another form of secondary liability, which is rooted in the tort theory of enterprise liability because, unlike contributory infringement, knowledge is not an element of vicarious liability. The law has developed the view that some relationships by their nature require the person who engages others to accept responsibility for the wrongdoing of those others. The most important such relationship for practical purposes is that of employer and employee. Employers are vicariously liable, under the respondeat superior doctrine, for negligent acts or omissions by their employees in the course of employment (sometimes referred to as 'scope and course of employment'). To determine whether the employer is liable, the difference between an independent contractor and an employee is to be drawn. In order to be vicariously liable, there must be a requisite relationship between the defendant and the tortfeasor, which could be examined by three tests: Control test, Organisation test, and Sufficient relationship test. An employer may be held liable under principles of vicarious liability if an employee does an authorized act in an unauthorized way. Employers may also be liable under the common law principle represented in the Latin phrase, qui facit per alium facit per se (one who acts through another acts in one's own interests). That is a parallel concept to vicarious liability and strict liability, in which one person is held liable in criminal law or tort for the acts or omissions of another. In Australia, the 'sufficient relationship' test, entailing the balancing of several factors such as skill levels required in the job, pay schemes, and degree of control granted to the worker, has been the favoured approach.
