    Katherine H. Newman, Respondent, v. John T. Lee, Appellant.
    
      The manager of a stockbroker’s office held to be his general agent—contract in violation of the rules of the stock exchange — in what case , the customer is bound by such rules—private instructions to the manager—error in ihe rejection of evidence on, ■ a trial before the court, when disi-egard'ed.
    
    A manager of a stockbroker’s office, to whom the broker intrusts the conduct of the business, is, as between the principal and parties dealing with him, the general agent for the transaction of the business, and his acts, done in the course of the business, will, as between his principal and strangers, bind the principal, although he violates some private instructions given by the principal and not known to the public.
    In an action brought against the broker upon a contract made' by the manager, when acting within the apparent scope of his authority, evidence that the broker did not authorize the manager to-make the contract in question and ; that the broker was prohibited -from making such contract by a rule of the stock exchange, of which he was a member, is inadmissible against the plaintiff where it does, not appear that the latter knew of the rule in question or knew that the defendant was a member of any exchange.
    Such a rule is in the nature of a “ private instruction ” given to the agent, which is binding only upon a person having knowledge of it.
    While a customer of a stockbroker would probably be regarded as having consented that the custom of brokers should govern the transaction, such consent presupposes that the broker has acted and will act within the rules of his stock exchange, and the client is entitled to act upon the presumption that neither the broker nor his agent will enter into engagements contrary to the custom of the business or the rules of their exchanges.
    An error in the rejection of evidence, committed on the trial of an action before a court without a jury, does not constitute ground for a reversal of a .judgment rendered as the result of such trial, where the Appellate Division can see, upon an examination of the whole case, that the party offering the evidence was not prejudiced by its rejection. '
    Appeal by the defendant, John T. Lee, from a judgment of the Municipal Court of the city of New York, borough of Brooklyn, in favor of the plaintiff, entered on the 13th day of April, 1903, after a trial before the court without a jury.

   Woodward, J.:

This action was to recover an amount deposited as a margin, in certain stock transactions, with the manager- of one of the offices where the defendant carried on business as a broker. The answer is a general denial. The trial was before the court without a jury, and the defendant appeals from a judgment in favor of the plaintiff.

The trial court admitted, over the plaintiff’s objection, certain testimony tending to show that neither the plaintiff nor the defendant’s manager intended at any time to deliver or accept shares, but merely to pay differences according to the rise or the fall of the market. This testimony the court held insufficient to establish the illegality of the contract as a wagering agreement, and the conclusion is fairly sustained by the evidence. It is, therefore, unnecessary to pass upon the correctness of the court’s ruling in admitting the evidence as competent under the general denial in the answer. (See Goodwin v. Massachusetts Mut. Life Ins. Co., 73 N. Y. 480, 496.)

We think Brown, the defendant’s manager, was acting within the apparent scope of his authority as agent of the defendant in making this contract, and that the defendant is, therefore, bound by his act. He was more than a special agent of the defendant; he was a general agent for the transaction of the particular business in which he was engaged when he made this contract. “ Where an agent is intrusted to do a 'particular kind of business, he becomes, as between the principal and parties dealing with him, the general agent for the transaction of that business; and his acts, as between his principal and strangers, in that particular line, will bind the principal, although he violates some private instructions, given by his principal, not known to the public.” (Cox v. Albany Brewing Co., 56 Hun, 489, 491.)

It is contended by the defendant that inasmuch as this was a discretionary order” the defendant is not bound by his agent’s act. Hpon this point evidence was offered to. show that the defendant did not authorize the making of the contract; that he' was prohibited from taking this kind of order by the rules of the exchange of which he was a member, and, therefore, could not authorize an agent to do this class of business. The evidence was rejected.

It seems to us that the rules are private instructions ” within the meaning of that term as used in the Cox case, above cited. Surely they have not the force of general laws, which every man is presumed to know. Their only sanction is that' of the body making them, and that organization can inflict penalties for their violation "only on its members. It is not contended that a contract made in violation of the rules is in any sense tainted with illegality. The rules of stock exchanges do not differ essentially in respect to their operation among persons who are not members from the by-laws of business corporations. These are binding upon third persons only when those persons have knowledge of them. It does not appear that the plaintiff had knowledge of the rule in question, or that she even knew the defendant was a member of any exchange. To her the defendant was merely a broker, and Brown his manager and agent. The rule here invoked is one restricting the powers which would ordinarily belong to an agent of Brown’s class; that is," the class of brokers’ agents-, t The plaintiff was not bound by the rule. “ By-laws of business corporations are as to third persons private regulations binding as between the corporation and its members or third persons having knowledge of them, but of no force as limitations per se as to third persons of an authority, which, except for the by-law, would be construed as within the apparent scope of the agency.” (Rathbun v. Snow, 123 N. Y. 343, 349, citing Morawetz Corp. [2d ed. § 593.)

While, perhaps, the plaintiff must be presumed to have consented that the transaction be conducted according to the custom of brokers (Horton v. Morgan, 19 N. Y. 170), yet evidence of that custom, which is in this case crystalized in the form of written rules, should be admitted only to show that a course of dealing between a broker and his client, regular in its inception,, was or was not carried on in accordance with such custom. The doctrine of Horton v. Morgan (supra) does not permit a broker to retain a 'Client’s funds Upon the plea that he received them irregularly, and to be sustained in this contention by proof of the rules of his exchange or the custom of his business. If he cannot use the rules as a shield for his own irregular acts, the acts of his agent, whom he has apparently given full authority for the purposes of his business, cannot be repudiated on the ground 'that they are forbidden by the rules. ' If the client is to be regarded as having consented, by employing a broker, that the custom of brokers shall govern the transaction, the consent presupposes that the broker has acted and will act within the rules, and the client is entitled to act upon the presumption that neither the broker nor his agents will enter into engagements contrary to the custom of the business or the rules of their exchanges.

The testimony was properly rejected. But even conceding the ruling to have been error, still it satisfactorily appears from an examination of the whole case that the defendant was not prejudiced by the exclusion of the evidence, especially as the case was tried before the court without a jury. (See Truman v. Lombard, 10 App. Div. 430, 434.)

The assignment of the claim in suit to the plaintiff appears to be in all respects properly acknowledged, authenticated and-proved. (Laws of 1896, chap. 547, § 261; R. S. of Ontario, 1897, chap. 175.)

The other exceptions raise no point of reversible error, and the judgment should be affirmed.

Bartlett, Hirschberg, Jenks and Hooker, JJ., concurred.

Judgment of the Municipal Court affirmed, with costs.
