Chapter: What is the legal term for someone who has the power to act on behalf of someone else? (EN)

I. Agency and Representation

The legal term for someone who has the power to act on behalf of someone else is an agent. This power stems from a legal relationship known as agency. Agency is a fiduciary relationship, which implies a high degree of trust and good faith.

• Definition of Agency: Agency is the fiduciary relationship that arises when one person (a “principal”) manifests assent to another person (an “agent”) that the agent shall act on the principal’s behalf and subject to the principal’s control, and the agent manifests assent or otherwise consents so to act. (Restatement (Third) of Agency § 1.01)

• Key Elements:

  1. Principal: The person who grants authority to another.
  2. Agent: The person who is authorized to act on behalf of the principal.
  3. Manifestation of Assent: A clear indication, either express or implied, that the principal desires the agent to act on their behalf.
  4. Control: The principal’s right to direct the agent’s actions.
  5. Fiduciary Duty: The agent’s obligation to act in the best interests of the principal.

II. Types of Agency Relationships

Agency relationships can be categorized based on various factors, including the scope of authority granted and the nature of the relationship.

1. Express Agency: Arises when the principal explicitly grants authority to the agent, either orally or in writing. A written instrument creating this authority is often called a power of attorney.
2. Implied Agency: Authority not expressly granted but reasonably inferred from the principal’s conduct, the nature of the agent’s position, or prior dealings. This is often tied to the concept of apparent authority (see section IV).
3. Apparent Agency (Agency by Estoppel): Occurs when the principal’s actions lead a third party to reasonably believe that an agent has authority, even if no actual authority exists. The principal is then estopped (prevented) from denying the agency relationship.
4. Agency by Ratification: Even if no prior authority existed, the principal can ratify (approve) the agent’s actions retroactively, creating an agency relationship.
5. Gratuitous Agency: Agency where the agent receives no compensation. While not compensated, the agent still owes fiduciary duties to the principal.

III. Scope of Authority

The agent’s authority determines the extent to which they can bind the principal in legal transactions. Authority is critical for understanding liability and responsibility.

1. Actual Authority: The authority the agent reasonably believes they possess based on the principal’s communications.

   • Express Actual Authority: Authority explicitly granted to the agent (e.g., “You are authorized to sign contracts up to \$10,000”).
   • Implied Actual Authority: Authority that is reasonably inferred from the express authority or from the nature of the agent’s position. For example, a store manager has implied authority to order inventory.

2. Apparent Authority: The authority a third party reasonably believes the agent possesses based on the principal’s representations or conduct. This is crucial in protecting third parties who rely on the agent’s actions.

3. No Authority: When the agent acts without actual or apparent authority, the principal is generally not bound by the agent’s actions, unless the principal ratifies those actions.

IV. Fiduciary Duties of an Agent

An agent owes several fiduciary duties to the principal, which are crucial to the agency relationship’s integrity.

1. Duty of Loyalty: The agent must act solely for the benefit of the principal and avoid conflicts of interest. This includes:

   • Not competing with the principal.
   • Not disclosing confidential information.
   • Not taking personal advantage of opportunities that belong to the principal.

2. Duty of Obedience: The agent must follow the principal’s lawful instructions.

3. Duty of Care: The agent must act with reasonable care, competence, and diligence. The standard of care often depends on the agent’s skill level and the nature of the task. This can be expressed as:

   • Care Level = f(Skill, TaskComplexity)

4. Duty of Accounting: The agent must keep accurate records of all transactions made on behalf of the principal and account for all funds received.

5. Duty of Disclosure: The agent must disclose all material facts relevant to the agency relationship to the principal.

V. Liability in Agency

Understanding liability within an agency relationship is critical for both the principal and the agent.

1. Principal’s Liability: A principal can be held liable for the agent’s actions if the agent acted within their actual or apparent authority. The theory of respondeat superior makes the principal liable for the torts (wrongful acts) committed by an agent or employee while acting within the scope of their employment.

2. Agent’s Liability: An agent can be held liable to third parties in certain circumstances:

   • If the agent acts outside their authority.
   • If the agent commits a tort.
   • If the agent fails to disclose the principal’s identity.

3. Indemnification: If an agent incurs liability while acting on behalf of the principal, the principal may be required to indemnify (compensate) the agent for their losses.

VI. Termination of Agency

Agency relationships can be terminated in various ways.

1. By Agreement: The principal and agent can mutually agree to terminate the relationship.
2. By Lapse of Time: If the agency agreement specifies a duration, the agency terminates automatically at the end of that period.
3. By Fulfillment of Purpose: The agency terminates when the purpose for which it was created has been accomplished.

4. By Operation of Law: Termination can occur automatically due to events such as:

   • Death or incapacity of the principal or agent.
   • Bankruptcy of the principal or agent.
   • Destruction of the subject matter of the agency.
   • Illegality of the agency.

5. By Unilateral Act: Either the principal or the agent can terminate the agency relationship. However, if the termination breaches the agency agreement, the terminating party may be liable for damages. This is related to contractual law; a breach could involve damages D = ExpectedProfit - ActualProfit.

VII. Practical Applications and Examples

1. Real Estate Agent: A real estate agent acts as an agent for the buyer or seller in a property transaction. They have the authority to negotiate on their client’s behalf and must act in their client’s best interests.

2. Corporate Officer: A corporate officer is an agent of the corporation and has the authority to bind the corporation to contracts and other legal obligations.

3. Athlete’s Agent: An athlete’s agent negotiates contracts, endorsements, and other business deals on behalf of the athlete.

4. Power of Attorney: A document granting one person (the agent) the authority to act on behalf of another (the principal) in financial or medical matters.

VIII. Related Legal Concepts

1. Trust: A legal arrangement where one person (the trustee) holds property for the benefit of another (the beneficiary). While there are similarities, a trustee’s responsibilities are more extensive than those of an agent.
2. Independent Contractor: Unlike an agent, an independent contractor is not subject to the principal’s control over the manner and means of performing the work. The principal is generally not liable for the torts of an independent contractor.
3. Employee: An employee is an agent who is subject to the employer’s control. The employer is liable for the torts of an employee under the doctrine of respondeat superior.
4. Partnership: In a partnership, each partner is an agent of the partnership and has the authority to bind the partnership in business transactions.

IX. Scientific Discoveries and Breakthroughs Related to Legal Theory

While not a direct scientific discovery, the conceptualization and evolution of agency law reflects a societal “discovery” of optimal methods for decentralized decision-making and economic activity. Modern advancements in game theory and behavioral economics provide insights into the dynamics of agency relationships, including:

1. Principal-Agent Problem: This economic theory addresses the challenges that arise when the principal’s interests are not perfectly aligned with the agent’s interests. This is commonly expressed through incentive structures such as AgentEffort = α * PrincipalBenefit - β * AgentCost, where α and β represent the relative incentives for the agent.
2. Information Asymmetry: One party has more information than the other, leading to potential for opportunistic behavior. Legal frameworks like fiduciary duties aim to mitigate this.
3. Contract Theory: Designing contracts that effectively align the interests of the principal and agent.
