Ostensible agency. The defendant in his pleading made the following allegation as an answer to the actions: - "It was in accordance with custom and/or the ordinary course of business for a broker to pledge or deposit by way of security, for a loan made to the broker, share certificates together with transfers thereof signed in blank, by or on behalf of the person who appeared to be the owner of the certificates; and the defendant acted in accordance with such custom and in accordance with the ordinary course of business in lending money to the broker, against and in accepting the said certificates and transfers as a pledge or deposit." I understand this to mean that, according to the established course of a sharebroker's business, he not only sells in his own name, or without disclosing his principal, the stock and shares of his client and completes the sale by delivery of the scrip intrusted to him, but he also mortgages or pledges scrip intrusted to him for loans raised in his own name. I presume that it was hoped to shew under this allegation that it is the custom in Adelaide for a sharebroker to hold his clients' securities, consisting in the case of shares of the scrip and a blank signed transfer, as cover for his clients' indebtedness to him and to lodge securities so held by him with the broker's own bankers, or with other persons making advances to him, as mortgages or pledges to the full value of the stock or shares independently of the broker's interest therein, that is his title to retain them against his client. If that had been shown, a foundation would have been made for an ostensible authority in the broker, Hodgetts, which nothing but notice in the defendant would displace. Speaking of the supposed course of business, practice or usage, though rather in connection with the interpretation of the powers of attorney, Ligertwood J. said: - "By the practice of brokers he" (Hodgetts) "would still be acting in the conduct and management of the plaintiffs' affairs, if he redeposited the certificates for the purpose of obtaining money for his own business, because that is one of the means by which brokers are able to finance their customers. On the authorities I am entitled to take judicial notice of this practice. It was recognized by several of the Law Lords in London Joint Stock Bank v. Simmons1(1892) A.C. 201. and by Pickford J. in Fuller v. Glyn, Mills, Currie & Co.2(1914) 2 K.B. 168.. Indeed it was largely the recognition of the practice which enabled the House of Lords in Simmons' Case1(1892) A.C. 201. to distinguish their previous decision of Sheffield v. London Joint Stock Bank3(1888) 13 App. Cas. 333.. Lord Halsbury referred to the course of business which brokers habitually pursue towards their own clients and for their own clients, when dealing with bankers with whom they deposit securities and he said, the deposit of securities as cover in a broker's business is as well-known a course of dealing as anything can possibly be1(1892) A.C., at p. 211.. And Lord Macnaghten said, The only objection alleged is that securities of different customers of the stockbrokers were pledged for one entire advance. ... But even so, if the bank had no reason to suppose that the stockbrokers were not at liberty to pledge each and all of the securities for their full value, I cannot see in what the supposed want of good faith consists. As was pointed out in Foster v. Pearson2(1835) 1 C.M. & R. 849 [149 E.R. 1324]. such a practice - and the practice prevails in the case of stockbrokers as much as in the case of bill-brokers - has advantages for the customers as a body, though it may occasionally operate hardly on an individual3(1892) A.C., at p. 225.. The advantage is that by pledging his customer's securities for his own business debt, the sharebroker may be able to give his customer a loan on more favourable terms than the customer could obtain by pledging his own securities (see per Lord Field4(1892) A.C., at p. 228.)"[57].
