The Extent of an Agent's Authority in Practice: Sections 188 and 189 Applied, Ambiguous Instructions, the Usual Authority of Particular Classes of Agent, and the Working Line Between Actual and Apparent Authority

Sections 188 and 189 are short and the propositions they state are easy. The difficulty is always in the application: how far does authority to do one thing carry authority to do another, what happens when the instructions are ambiguous, and what is the usual authority of a broker, a factor, an auctioneer or a company officer? This topic takes the provisions as they operate in practice. It sets out how a court determines the scope of authority, what an agent should do when his instructions are unclear, and the authority usually attaching to the principal classes of agent, which is what decides most apparent-authority disputes.

1. The Provisions

Sections 188 and 189, Indian Contract Act, 1872

188. Extent of agent's authority. An agent, having an authority to do an act, has authority to do every lawful thing which is necessary in order to do such act.

An agent having an authority to carry on a business has authority to do every lawful thing necessary for the purpose, or usually done in the course, of conducting such business.

189. Agent's authority in an emergency. An agent has authority, in an emergency, to do all such acts for the purpose of protecting his principal from loss as would be done by a person of ordinary prudence, in his own case, under similar circumstances.

The two paragraphs of Section 188 do different work. The first is incidental authority and is measured by necessity: what must be done to accomplish the authorised act. The second is usual authority and is measured by practice: what is ordinarily done in conducting a business of that kind. The second is far wider, which is why an authority to carry on a business confers much more than an authority to do a single act.

2. How a Court Determines the Scope

Start with the express words, construed in their commercial context and not in the abstract. Authority to sell does not import authority to sell on credit unless that is the practice.
Ask what is necessary to accomplish the act, under the first paragraph of Section 188. Authority to recover a debt imports authority to adopt any legal process for the purpose and to give a valid discharge, as Illustration (a) states.
Ask what is usually done in that business, under the second paragraph. Authority to carry on a shipbuilding business imports authority to buy timber and hire workmen, as Illustration (b) states.
Consider the course of dealing between these parties, which Section 187 makes a circumstance of the case.
Consider the trade usage, provided it is reasonable and lawful and not inconsistent with the agency.
Ask whether the third party knew of any limitation. If he did, he cannot rely on an appearance of authority; if he did not, Section 237 may bind the principal notwithstanding the limitation.

3. Ambiguous Instructions

📖 Ireland v. Livingston, (1872) LR 5 HL 395

Facts: A principal instructed his agent abroad to ship 500 tons of sugar, adding that 50 tons more or less would be of no importance if it enabled the agent to get a suitable vessel. The agent, unable to obtain a vessel for the whole quantity at once, shipped about 400 tons and intended to send the balance later. The principal refused to accept the part shipment, contending that the instructions required a single shipment of about 500 tons.

Held: The House of Lords held that where instructions are ambiguous and are reasonably capable of two constructions, an agent who bona fide adopts one of them and acts on it is not liable to the principal for having failed to adopt the other. The principal, having sent ambiguous instructions, must bear the consequences of the ambiguity. The proper course for the principal is to express himself clearly, and the proper course for the agent, where he can, is to seek clarification.

Ratio: An agent who acts honestly on a reasonable construction of ambiguous instructions is protected. The risk of ambiguity lies on the principal who created it.

⚠ The protection in Ireland v. Livingston has narrowed

The rule remains good but the courts now apply it more strictly, for a practical reason: modern communications make it far easier for an agent to ask. Section 214 requires the agent, in cases of difficulty, to use all reasonable diligence in communicating with his principal and in seeking his instructions. An agent who could readily have clarified an ambiguity and did not will find it hard to say that he acted reasonably, and the same reasoning defeated the carrier in Springer v. Great Western Railway Co., [1921] 1 KB 257 on the related question of agency by necessity. Ireland v. Livingston protects the agent who genuinely could not ask, not the agent who did not trouble to.

4. Actual Authority Implied from Conduct

📖 Hely-Hutchinson v. Brayhead Ltd., [1968] 1 QB 549 (CA)

Facts: The chairman of a company acted throughout as its de facto managing director, committing the company to contracts and reporting them to the board, which acquiesced in his doing so. He had never been formally appointed managing director. He signed letters of indemnity and guarantee in favour of the plaintiff. The company denied that he had authority to bind it.

Held: The company was bound. Lord Denning MR distinguished the two kinds of authority. Actual authority may be express or implied, and it is implied where the board, by its conduct over months, acquiesces in a person acting as managing director; that person then has actual authority to do all the things usually falling within the scope of that office. Apparent authority is the authority as it appears to others, and it often coincides with actual authority. The chairman here had actual authority implied from the board's acquiescence, and the contracts bound the company.

Ratio: Actual authority may be implied from a course of conduct acquiesced in by those with power to confer it. Where it is, the principal is bound without any need to rely on apparent authority, and the agent is entitled to his indemnity under Section 222.

	Actual authority, implied	Apparent authority
What creates it	The conduct of the principal or board towards the agent, acquiesced in over time	A representation by the principal to the third party
Does the agent have real power?	Yes	No; the principal is merely estopped
Is the agent entitled to indemnity?	Yes, under Section 222, the acts being within his authority	No. He acted outside his authority and may be liable to the principal
Does the third party's state of mind matter?	No	Yes; he must have relied on the representation
Typical case	A de facto managing director, per Hely-Hutchinson	A manager with secret restrictions, per Watteau v. Fenwick

The practical importance of the distinction is to the agent. Where his authority was actual, he is protected by Section 222 and may claim his indemnity. Where the principal is bound only by apparent authority, the agent has exceeded what he was permitted to do; the third party is safe, but the agent is answerable to his principal for the excess and may also face a claim under Section 235 if the principal disowns the transaction.

5. The Usual Authority of Particular Agents

Because the second paragraph of Section 188 measures authority by what is usually done, the recognised profile of each class of agent does most of the work in practice.

Class of agent	Usually has authority to	Usually has no authority to
Broker	Negotiate and conclude contracts in the principal's name; sign a contract note binding both parties	Receive payment of the price, or sell in his own name, or deliver the goods
Factor	Sell in his own name, receive the price, give a valid receipt, and pledge the goods under Section 178; he has a general lien under Section 171	Barter the goods, or sell on terms outside the ordinary course of business
Del credere agent	Everything a factor may do, and in addition he guarantees the solvency of the buyer for an extra commission	Vary the principal's terms, his guarantee being collateral only
Auctioneer	Sell to the highest bidder, receive the deposit and sign a memorandum binding both parties; he has a particular lien for his charges	Sell on credit, or warrant the seller's title, or sell below a reserve of which he has notice
Commission agent	Buy or sell on the principal's behalf on the best terms available, in the ordinary course	Depart from instructions, or deal on his own account under Sections 215 and 216
Partner	Bind the firm by acts done in the usual way of its business, under Section 19 of the Indian Partnership Act, 1932	Submit disputes to arbitration, open a bank account in his own name for the firm, compromise a claim, or transfer immovable property of the firm, absent express authority
Company officer	Do what is usual for the office held: a managing director to manage, a secretary to make administrative contracts	Exceed what is usual for the office, or act where the third party knows of the limitation
Holder of a power of attorney	Exactly what the instrument confers, construed strictly	Anything not fairly within the words; powers of attorney are read restrictively and general words are limited by the specific powers granted

6. Emergency Authority in Operation

There must be a genuine emergency, not mere inconvenience or an opportunity for advantage.
The act must be for the purpose of protecting the principal from loss, and not for the agent's own benefit.
The standard is that of a person of ordinary prudence acting in his own case, which is objective and neither requires perfection nor excuses recklessness.
The agent should still try to communicate. Section 214 requires it in cases of difficulty, and Section 189 operates where instructions cannot be obtained in time.
Illustration (b) is the model: a consignee may sell provisions locally if they will not survive the onward journey.
Where the emergency passes, the authority lapses, and the agent must revert to his instructions.

7. Where the Agent Exceeds His Authority

If the excess is separable, Section 227 binds the principal to the authorised part only.
If it is inseparable, Section 228 releases the principal from the transaction altogether.
The principal may ratify under Sections 196 to 200, but only the whole transaction, under Section 199.
The third party may hold the agent liable for breach of warranty of authority under Section 235, unless the principal ratifies.
The principal may be bound notwithstanding under Section 237, where his own words or conduct induced the third party to believe the act was authorised.
The agent loses his indemnity under Section 222, which covers only acts within the authority conferred, and may be liable to the principal under Sections 211 and 212.

8. The Position Stated Shortly

The first paragraph of Section 188 confers incidental authority measured by necessity; the second confers usual authority measured by what is ordinarily done in the business.
Scope is determined from the express words, what is necessary, what is usual, the course of dealing, trade usage, and the third party's knowledge.
Ireland v. Livingston: an agent who acts honestly on a reasonable construction of ambiguous instructions is protected, the risk of ambiguity lying on the principal.
That protection has narrowed, because Section 214 requires the agent to seek clarification where he can.
Hely-Hutchinson v. Brayhead: actual authority may be implied from a board's acquiescence in a person acting as managing director.
The distinction between implied actual authority and apparent authority matters most to the agent, because only the first carries the indemnity under Section 222.
The usual authority of brokers, factors, del credere agents, auctioneers, partners and company officers is settled and does most of the work in practice.
A power of attorney is construed strictly and general words are limited by the specific powers granted.
Section 189 confers emergency authority judged by the standard of a person of ordinary prudence acting in his own case.
An excess of authority is governed by Sections 227 and 228, may be cured by ratification, and exposes the agent under Sections 222 and 235.
