Implied Authority of Partner (Section 19) →

Section 19 of the Indian Partnership Act, 1932 is the engine of partnership liability to outsiders. Because every partner is, by Section 18, an agent of the firm for the purpose of its business, the law clothes each partner with an authority to bind the firm even where no express power has been given. That authority — the power to do, in the usual way, the business of the kind carried on by the firm — is the partner's implied authority. It is what lets a third party deal with one partner and hold the whole firm liable, and it is the doctrinal bridge between the agency rule of Section 18 and the joint-and-several liability of Section 25.

This chapter sets out the meaning and source of implied authority, the two-part test that fixes its scope, the pivotal distinction between trading and non-trading firms, the eight statutory restrictions in Section 19(2), the mode of binding the firm under Section 22, the power of partners to extend or restrict authority by contract under Section 20, the emergency authority of Section 21, and the relationship between implied and apparent authority. The topic builds on the agency foundation laid in our chapters on the introduction, scheme and definitions and the nature of partnership and its essentials.

Partner as agent and the statutory anchor

The starting point is Section 18: "Subject to the provisions of this Act, a partner is the agent of the firm for the purposes of the business of the firm." This is the principle of mutual agency, the very test of partnership identified by the House of Lords in Cox v. Hickman, (1860) 8 HL Cas 268, where the true question was held to be whether the person carrying on the business did so as agent for the person sought to be charged. Mutual agency is the feature that separates a partnership from co-ownership, a Hindu undivided family, a company or a club, none of which carries the reciprocal agency that makes one member's act the act of all.

From this agency relation the law derives a partner's authority to act for the firm. That authority may be express — conferred by the partnership deed or by agreement — or it may be implied. Section 19 deals with the implied variety. As Lord Cranworth put it in the line of authority on which the section rests, the liability of one partner for the acts of his co-partner is in truth the liability of a principal for the acts of his agent: where two or more persons are engaged as partners in an ordinary trade, each has an implied authority from the others to bind all by contracts entered into in the course of business.

What implied authority means

Implied authority is so called because it arises by implication of law as a legal incident of the formation of a firm; it need not be expressly conferred. The justification is commercial. A third party dealing with a firm cannot always know what authority has been given to each partner; but he is entitled to assume that, since a partner is an agent of the firm, the partner may do whatever is necessary to carry on the firm's business in the usual way. The firm is therefore made liable for acts falling within that implied authority even though, as between the partners themselves, the act may have been unauthorised.

Implied authority is thus the firm's exposure to the ordinary, expected acts of its partners. It is wide enough to cover the everyday transactions of the trade, but it is bounded — the act must be both connected to the partnership business and done in the usual way of that kind of business. Where either limb fails, the firm is not bound by Section 19 alone, though it may yet be bound by express authority, by apparent authority under Section 27, by ratification, or by the holding-out principle of Section 28.

The two-part test of scope

For an act to fall within a partner's implied authority, two conditions must be satisfied. First, the act must be done in relation to the partnership business — an act done for the partner's private purposes, or wholly outside the firm's trade, cannot bind the firm. Second, the act must be done in the usual way of carrying on a business of the kind carried on by the firm. What is "usual" is not fixed; it is a question to be determined by the nature of the business and by the practices of persons engaged in it, and it may vary from place to place and from time to time.

The phrase "business of the kind carried on by the firm" is the controlling idea. What is usual for one kind of business may be wholly unusual for another. A partner in a firm of sugar merchants has implied authority to buy and sell sugar, but not to accept deposits; a partner in a firm of bankers may accept deposits and deal in negotiable instruments, but a purchase of sugar by him would fall outside his implied authority. The nature of the business therefore determines the scope of the authority, and the inquiry is always objective — what would a person dealing with such a firm reasonably expect a partner to be authorised to do.

Trading versus non-trading firms

For the purpose of implied authority the courts have drawn a long-standing distinction between trading and non-trading firms, most sharply on the power to borrow. In a trading firm — one whose business consists in buying and selling, or which necessarily requires credit and circulating capital — a partner has implied authority to borrow money on the firm's credit, to pledge the firm's goods as security, and to draw, accept or endorse negotiable instruments. In a non-trading firm such powers are not implied; they must be expressly conferred.

In Bank of Australasia v. Breillat, (1847) 6 Moo PC 152, the Privy Council observed that in a banking business — necessarily exposing the banker to sudden demands for repayment of deposits — the person in charge must be deemed to have implied power to borrow; such power exists in every business that cannot be carried on in the usual way without it. The converse appears in Higgins v. Beauchamp, (1914) 3 KB 1192, where two partners carried on business as cinematograph-theatre proprietors, one of them a sleeping partner. The managing partner borrowed money from the plaintiff, representing that it was for the business, and then misappropriated it. The firm was held not liable: a cinema business is not a trading business, so borrowing was not within a partner's implied authority and the sleeping partner could not be charged.

By contrast, in Saremal Punamchand v. Punamchand, where the firm's business consisted in buying and selling brass and copper utensils, two partners borrowed money admittedly for the partnership; the borrowing was held to be within implied authority because the firm was of a commercial nature in which a loan was usual. The reach of implied authority into transactions not expressly contemplated is illustrated by Mercantile Credit Co. Ltd v. Garrod, [1962] 3 All ER 1103: a garage partnership confined by its deed to letting lock-up garages and repairing cars was nonetheless bound when the active partner sold a car for hire-purchase, because to the outside world the sale of a car was an act of the kind done in a garage business, and the deed's internal restriction did not bind an innocent third party.

Illustrative instances of implied authority

Within the usual course of the firm's business, the cases recognise a broad range of acts as falling within implied authority. A partner may buy or hire on credit the kind of goods used in the firm's business; receive payments due to the firm and give a valid discharge to the debtor; engage and dismiss the servants of the firm; and acknowledge or pay the firm's debts. Where implied authority to contract exists, it carries with it the power to vary the terms of the contract according to business exigencies. In a trading firm the authority to borrow includes the authority to provide security by way of pledge, and the power to become a party to a negotiable instrument.

It is within a partner's implied authority to defend an action brought against the firm and to engage a lawyer for that purpose; a working partner may retain a solicitor to recover a debt due to the partnership, and a dormant partner will be liable for the fee. But the implied authority to defend does not extend to submitting to an injunction, consenting to judgment, or compromising a pending suit — those acts are expressly withdrawn by Section 19(2). Equally, where implied authority to borrow exists for the purposes of the business, it does not authorise borrowing to increase the capital of the partnership, which is a matter for the partners among themselves rather than an ordinary trading act.

Mode of binding the firm — Section 22

Section 19(1) is expressly made "subject to the provisions of section 22". Section 22 prescribes the manner in which a partner must act so that his act binds the firm: an act or instrument done or executed by a partner on behalf of the firm must be done or executed in the firm name, or in any other manner expressing or implying an intention to bind the firm. In short, either the contract is made straightaway in the firm's name, or the other party is made aware, expressly or by the mode of contracting, that the partner intends to bind the firm.

Where a partner signs in his own name without indicating that he acts for the firm, the firm is not bound and the dealing partner alone is liable. In Jankidas v. Sri Kishen Pershad, AIR 1918 PC 146, the Privy Council held that it is not enough that the principal's name be disclosed "in some way"; it must be disclosed so that, on a fair interpretation of the instrument, the principal's name is the real name of the person liable. The use of a firm's letterhead, without more, only helps to ascertain the executant's address. So in Punjab United Bank Ltd v. Muhammad Hussain, AIR 1934 Lah 358, a partner who signed a promissory note as "Proprietor, Punjab Alliance Auction Rooms" — giving no hint of a firm or of acting on its behalf — did not bind his co-partner. And in M.M. Abbas Bros v. Chetandas, AIR 1979 Mad 272, a signature "For M.M. Abbas & Co." was held to bind the firm, while a signature describing the signatory merely as "Partner of M.M. Abbas & Bros." did not, being only a description of the person signing. The lesson is that to bind a firm the signatory should sign "for" or "on behalf of" the firm — though if the tenor of the instrument itself shows it to be a document of the firm, the form of signature becomes immaterial.

Statutory restrictions under Section 19(2)

The breadth of implied authority is cut back by Section 19(2), which lists acts a partner cannot do under his implied authority. These restrictions apply "in the absence of any usage or custom of trade to the contrary", and they are binding on all persons dealing with the firm — a third party cannot say he was unaware of them, for it is his duty to know and ignorance is no excuse.

The eight clauses share a common rationale. Each concerns an act of unusual gravity — referring the firm's disputes to arbitration, dealing with the firm's immovable property, giving up the firm's claims, or admitting the firm's liability — that goes beyond the ordinary trading expectation and could seriously prejudice the other partners. The law therefore withholds these powers from the bare implied authority and requires either express authority, a usage or custom of trade, or ratification before such an act will bind the firm. The restriction in clause (e) is also the reason a partner cannot, in the ordinary course, admit liability in a suit against the firm under Section 23: an admission binds the firm only if made in the ordinary course of business, and admitting liability in litigation is not such a course.

Ratification, usage and the limits of the restrictions

A Section 19(2) act done without authority is not a nullity; it is merely unauthorised, and the firm may take advantage of it by ratification. Every principal has the power to ratify the unauthorised acts of his agent, and a subsequent approval — express or implied — by the other partners binds them. In M/s Luda Ram v. M/s Maharani of India, AIR 1989 Del 169, the principle was applied so that ratification of an otherwise unauthorised act rendered the firm bound. So if a partner without authority borrows a sum and the other partners ratify the act, they become bound to repay.

The restrictions also bend to usage or custom of trade. Because Section 19(2) opens with the words "in the absence of any usage or custom of trade to the contrary", a partner may do even a listed act if a settled usage of the particular trade permits it — for instance, a usage to refer business disputes of that trade to arbitration. Beyond the statutory list, the cases recognise further limits on implied authority: a partner cannot assign a debt of the firm, nor execute a guarantee on the firm's behalf for the debt of another person, and a partner who merely complains of a co-partner's unauthorised transactions but takes no further step, allowing them to stand in the partnership books, may be bound by acquiescence.

Extension and restriction under Section 20

Section 20 allows the partners to tailor implied authority by agreement: "The partners in a firm may, by contract between the partners, extend or restrict the implied authority of any partner." This freedom lets a firm give greater authority to senior, experienced partners and curtail the authority of new or inexperienced ones — a flexibility the legislature considered necessary for business expediency. Where authority is extended, the partner's real authority becomes wider than the implied authority, and any act within that extended authority binds the firm; the co-partners cannot object, having themselves conferred the wider power, a point illustrated in B.V. Narasimhulu v. R. Krishnamurthy, AIR 1986 AP 177.

The second limb of Section 20 protects third parties: "Notwithstanding any such restriction, any act done by a partner on behalf of the firm which falls within his implied authority binds the firm, unless the person with whom he is dealing knows of the restriction or does not know or believe that partner to be a partner." A contractual restriction therefore narrows the partner's real authority below his implied authority, but it does not affect an outsider unless that outsider has notice of it. If the restricted partner does an act that is forbidden internally but still falls within his implied authority, the firm is bound, leaving the firm to its remedy against the erring partner.

Knowledge of restriction — the third-party rule

The decisive question under Section 20 is whether the third party had actual knowledge of the restriction. This is the great difference between contractual restrictions under Section 20 and statutory restrictions under Section 19(2): the statutory restrictions bind all third parties, who are deemed to know them, whereas a contractual restriction binds a third party only if he in fact knows of it. Two cases mark the line. In Motilal v. Unnao Commercial Bank, (1930) 32 Bom LR 1571, a partnership deed restricted the partners' authority to borrow; a partner nonetheless borrowed and accepted a bill of exchange without the lender knowing of the restriction. The firm was held liable, because borrowing fell within implied authority and the third party had no notice of the internal limit.

In Prembhai v. Brown, (1873) 10 Bom HC Rep 319, the result was the opposite because the third party knew. A partner of a firm of carriers was authorised to draw bills on the firm only up to Rs. 200 each; this was known to a third party in whose favour the partner made two promissory notes for Rs. 1,000 each. The firm was held not bound, the restriction being within the third party's knowledge. The practical rule for the outsider is therefore simple: deal with a partner in good faith and without notice of internal limits, and the firm is bound for acts within implied authority; deal with notice of a restriction, and the firm escapes to the extent of the restriction.

Emergency authority under Section 21

Even where a partner has neither express nor implied authority for an act, his act may bind the firm if it is done in an emergency. Section 21 provides that a partner has authority, in an emergency, to do all such acts for the purpose of protecting the firm from loss as would be done by a person of ordinary prudence, in his own case, acting under similar circumstances; and such acts bind the firm. The standard is that of the ordinarily prudent person acting in his own affairs, and the object must be the protection of the firm from loss.

The authority conferred by Section 21 mirrors the emergency authority of an agent under Section 189 of the Indian Contract Act, 1872, which entitles an agent, in an emergency, to do all such acts for protecting his principal from loss as a person of ordinary prudence would do in his own case. A partner who makes a payment or incurs a liability in such an emergency, having acted as a prudent person would, is entitled to be indemnified by the firm; this indemnity is rooted in Section 13(e), which obliges the firm to indemnify a partner for liabilities incurred in protecting the firm from loss in an emergency, acting as a person of ordinary prudence would in similar circumstances.

Implied versus apparent authority

Implied authority must be distinguished from apparent (or ostensible) authority, which surfaces in Section 27 dealing with the firm's liability for a partner's misapplication of money or property. "Apparent authority" means the authority of an agent as it appears to others; to say that an act was within the scope of a partner's apparent authority is to say that the act appeared to be authorised. The scope of apparent authority may sometimes be wider than implied authority, although to a large extent the two coincide, because both depend on the usual manner of carrying on the business.

The point is sharpened by the misapplication cases. In Rhodes v. Moules, [1895] 1 Ch 236, a partner in a firm of solicitors, asked by a client to obtain a mortgage loan, told the client that the mortgagee wanted additional security and obtained share warrants payable to bearer, which he misappropriated; because it was within his apparent authority to receive such warrants and the firm habitually held such securities for clients, the other partners were liable. Conversely, in British Homes Assurance Corpn Ltd v. Paterson, [1902] 2 Ch 404, where a partner obtained a cheque payable to himself, not to the firm, and misappropriated it, the firm was not liable, because the transaction was outside the ordinary course of the firm's business and was, in substance, the partner's private dealing. The line, once again, is the usual course of the firm's business as it appears to the outside world.

Admissions, notice and firm liability

Implied authority radiates into the neighbouring sections of Chapter IV. Under Section 23, an admission or representation made by a partner concerning the affairs of the firm is evidence against the firm if it is made in the ordinary course of business — a direct consequence of the agency principle, since a partner is the firm's agent for its business. But the admission must be in the ordinary course; a partner cannot, as Section 19(2)(e) makes clear, admit liability in a suit or proceeding against the firm, that not being part of the ordinary course.

Under Section 24, notice to a partner who habitually acts in the business of the firm, on any matter relating to the firm's affairs, operates as notice to the firm — again because notice to an agent is notice to the principal. Notice to a dormant or sleeping partner does not suffice; the notice must reach an acting or managing partner, and it means actual, not constructive, notice. The section carries an exception for fraud: where a fraud on the firm is committed by or with the consent of a partner, notice to that partner is not notice to the firm, as in Bignold v. Waterhouse, (1813) 1 M & S 255, where a partner who privately allowed a friend's parcel to be carried free, without informing his co-partners, was himself party to the irregularity, so his knowledge was not imputed to the firm. Read together, Sections 18 to 27 form a single agency architecture, and Section 19 is its load-bearing wall: it fixes the ordinary measure of a partner's power to bind the firm, against which the extensions, restrictions, emergencies and frauds of the surrounding sections are all calibrated.

MCQ angle — the recurring distinctions

Several propositions recur in objective papers. First, implied authority under Section 19(1) requires two things together — the act must be in relation to the firm's business and done in the usual way of that kind of business; the source of the authority is Section 18 (mutual agency), and the controlling test of partnership itself is Cox v. Hickman. Second, the trading/non-trading distinction governs borrowing: implied authority to borrow exists in a trading firm but not in a non-trading firm — Higgins v. Beauchamp (cinema = non-trading) is the stock illustration. Third, the eight Section 19(2) restrictions should be memorised; a useful mnemonic groups them as the "arbitration, own-name banking, compromise, withdraw suit, admit liability, acquire/transfer immovable property, and new partnership" acts.

Fourth, the Section 19(2)/Section 20 distinction is a favourite: statutory restrictions bind all third parties (deemed knowledge); contractual restrictions bind a third party only with actual knowledge — Motilal v. Unnao Commercial Bank (no notice, firm bound) versus Prembhai v. Brown (notice, firm not bound). Fifth, Section 21 confers emergency authority on the standard of the ordinarily prudent person, mirroring Section 189 of the Contract Act, with indemnity under Section 13(e). Sixth, Section 22 is the "mode" rule — sign in the firm name or in a manner expressing intention to bind the firm; a signature merely describing the signatory as a partner does not bind the firm.

Takeaways for the exam and the practitioner

For the aspirant, the structure to carry forward is this. Section 18 supplies the agency; Section 19(1) supplies the ordinary measure of authority, bounded by the two-part test and the nature of the business; Section 19(2) carves out eight grave acts; Section 20 lets the partners extend or restrict by contract, effective against outsiders only on notice; Section 21 adds an emergency authority; and Section 22 prescribes the mode of execution. The firm's liability to a third party turns on whether the act is within the partner's authority — express, implied, apparent, extended, emergency, or ratified — as it appears to a person dealing honestly with the firm.

For the practitioner, the working questions are: was the act in relation to the firm's business and usual for the trade; is the firm trading or non-trading on the borrowing point; does the act fall within the Section 19(2) list, and if so is there express authority, usage, or ratification; was there a Section 20 restriction and did the outsider have notice of it; and was the instrument executed in a manner that binds the firm under Section 22. The next steps in the syllabus — the distinctions between partnership and cognate relations and the agency-grounded liabilities of Sections 25 to 27 — all build on the measure of authority that Section 19 supplies, so it repays careful learning.
