The directors and officers of banking institutions must, of course, be entrusted with wide discretion in the granting or denying of loans. But that discretion should be exercised, not only honestly as it affects stockholders, but also impartially as it affects the public. Mere honesty to the stockholders demands that the interests to be considered by the directors be the interests of all the stockholders; not the profit of the part of them who happen to be its directors. But the general welfare demands of the director, as trustee for the public, performance of a stricter duty. The fact that the granting of loans involves a delicate exercise of discretion makes it difficult to determine whether the rule of equality of treatment, which every public-service corporation owes, has been performed. But that difficulty merely emphasizes the importance of making absolute the rule that banks of deposit shall not make any loan nor engage in any transaction in which a director has a private interest. And we should bear this in mind: If privately-owned banks fail in the public duty to afford borrowers equality of opportunity, there will arise a demand for government-owned banks, which will become irresistible. The statement of Mr. Justice Holmes of the Supreme Court of the United States, in the Oklahoma Bank case, is significant: “We cannot say that the public interests to which we have adverted, and others, are not sufficient to warrant the State in taking the whole business of banking under its control. On the contrary we are of opinion that it may go on from regulation to prohibition except upon such conditions as it may prescribe.” OFFICIAL PRECEDENTS Nor would the requirement that banks shall make no loan in which a director has a private interest impose undue hardships or restrictions upon bank directors. It might make a bank director dispose of some of his investments and refrain from making others; but it often happens that the holding of one office precludes a man from holding another, or compels him to dispose of certain financial interests. A judge is disqualified from sitting in any case in which he has even the smallest financial interest; and most judges, in order to be free to act in any matters arising in their court, proceed, upon taking office, to dispose of all investments which could conceivably bias their judgment in any matter that might come before them. An Interstate Commerce Commissioner is prohibited from owning any bonds or stocks in any corporation subject to the jurisdiction of the Commission. It is a serious criminal offence for any executive officer of the federal government to transact government business with any corporation in the pecuniary profits of which he is directly or indirectly interested.
