Qui facit per alium facit per se is a Latin legal term meaning, "He who acts through another does the act himself." It is a fundamental maxim of the law of agency.[1] This is a maxim often stated in discussing the liability of employer for the act of employee."[2]
According to this maxim, if in the nature of things the master is obliged to perform the duties by employing servants, he is responsible for their act in the same way that he is responsible for his own acts.[3]
