The principal is only liable if the agent was acting within the scope of his authority. Authority implies permission to do or engage in a particular act. It differs from power which is a legal concept. Whereas authority creates power, power may exist without authority. Though the two concepts are at times used interchangeably, they are not the same.
In certain circumstances, the agent has power but no authority e.g. an agent of necessity. Authority is the ability of the agent to effect the principal’s legal position in relation to 3 rd parties.
There are 3 types of authority an agent may have namely:
- Real or Actual.
- Ostensible or Apparent.
This is the authority which the agent has been given the principal under the contract between them. The authority may be express, implied, customary or usual.
- Express Authority: It is the authority given to the agent the principal in writing or word of mouth. If in writing, it is interpreted restrictively.
- Implied Authority: It is the agent’s authority implied from the nature of the business or transaction which the agent is engaged to transact. It is the authority reasonably necessary to accomplish express authority.
- Customary or Usual Authority: It is the agent’s authority implied from the customs, usage and practices of the transaction or business. It is the authority which every agent in a particular business or profession is deemed to have and 3rd parties dealing with such agents expect such authority. It is a category of implied authority. Agents created agreement or ratification exercise real or actual authority.
It is the authority which the agent has not been given the principal but which he appears to have reason of the principal’s conduct. It is therefore apparent. Its scope is determined the conduct of the principal. It is the authority exercised agency created estoppel.
It is a category of authority created law and which an agent is deemed to have in certain circumstances. It is not given to the agent nor is it based on the principal’s conduct. It is given operation of the law. It is agency created necessity or cohabitation
Liability for breach of contract
If an agent with no authority to act warrants the same to a 3rd party who relied on the representation and suffers loss or damage, the 3rd party may have an action in damages against the agent for breach of authority.
It is a situation wherethe principal who is indebted to the agent gives the agent authority as a security for a debt. The agent has a personal interest in the relationship. In such a case the agent’s authority lies irrevocable the principal.
