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.
This is especially true if the third party is made aware of the agent's authority limitations. In this situation, the third party may still attempt to sue the principal for any damages caused. However, the principal can then turn around and sue the agent to recover any damages caused.
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.
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.
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.
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.
The principal will be liable for the employee's torts in two circumstances: first, if the principal was directly responsible, as in hiring a person the principal knew or should have known was incompetent or dangerous; second, if the employee committed the tort in the scope of business for the principal.
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.
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.
