A principal is always liable for torts committed while the agent completes their official responsibilities. For torts occurring outside of official duties, the liability of the principal depends on whether the agent's tort occurred during a frolic or a detour.
A principal can be held directly liable for their agent's tortious conduct when their agent is acting with actual or true authority on the principal's behalf.
An agent is liable to a principal when he/she acts without actual authority, but with apparent authority. An agent is liable to indemnify a principal for loss or damage resulting from his/her act. A principal owes certain contractual duties to his/her agent.
Similarly, if the agent or principal loses capacity to enter into an agency relationship, it is suspended or terminated. The agency terminates if its purpose becomes illegal. Even though authority has terminated, whether by action of the parties or operation of law, the principal may still be subject to liability.
Tort liability is predicated on the existence of proximate cause, which consists of both: (1) causation in fact, and (2) foreseeability. A plaintiff must prove that his or her injuries were the actual or factual result of the defendant's actions.
A person is always liable for her own torts, so an agent who commits a tort is liable; if the tort was in the scope of employment the principal is liable too. Unless the principal put the agent up to committing the tort, the agent will have to reimburse the principal.
Principal's liability for acts of agent A principal is normally liable for all acts of an agent within the agent's authority, whether responsibility arises in contract or in tort. Authority means the agent's actual, apparent (ostensible) or usual (customary) authority.
An unidentified or partially disclosed principal is one that the other party to a transaction knows only that the agent may be acting on behalf of but not the identity of that principal; both the agent and the undisclosed principal are liable for such transactions.
