The trustees of the Arundel Provident Bank found they had a surplus accumulated before the Act and not required for the future management of the Bank, and, as they considered that a new bridge was needed over the river at Arundel, they devoted part of the surplus to the purpose of providing one. Some dissenting trustees and some depositors brought a suit as representative parties, without joining the Attorney-General, for a decree ordering restoration of the funds. Lord Brougham[19], upon an interlocutory motion in Chancery, expressed the opinion that the surplus must be applied for the purposes of the institution, and proceeded to remark upon the impossibility of treating the accumulations and surplus, whether past, present or future, as distributable in respect of the deposits which actually produced that fund, because depositors were a continually changing body, and he suggested that it was to be applied to the "corporate" purposes of the bank such as the supply of future deficits or other contingencies. The suit was heard by Shadwell V.C.[20], who held that the trustees had misapplied the surplus, and observed, after a consideration of the provisions of the Act, that it led him "to infer that the Legislature did contemplate nothing but an appropriation, which, in some manner or other, should be for the benefit of the general depositors"[21]. From this decree those trustees held liable appealed to the House of Lords, which affirmed the decision. Lord Cottenham L.C. said[22]: - "Before the passing of the Act 9 Geo. IV. c. 92, no question could have arisen as to the discretionary application of such a fund; under all former Acts, and on principle, the profits arising from deposits could only be applied for the benefit of the depositors, and nothing less than the authority of an Act of Parliament could warrant any other application against the will of the parties: no other persons could by possibility have any right to the fund, or could direct the application of it, except by contract between the parties and under their authority. There was no such contract as to this fund, and the trustees created by former Acts held in trust for the depositors all the moneys deposited, and all profits arising from the employment of the moneys." His Lordship went on to say that the policy of the statute was to regulate the investment of a surplus which accrued after it came into force, but not to divert a fund which had already accumulated. Both the frame of this suit and the observations of the Judges mark a tendency to regard the depositors for the time being as having beneficial interests in the funds of the Bank. Yet the constitution of the Bank and the provisions of the statute seem consistent with the view that the "purposes of the institution" which its funds were to answer were not the proprietary interests of the depositors for the time being, but the encouragement of thrift, and the promotion of social welfare by performing the gratuitous and benevolent service of receiving deposits of money from the public at large at interest, and affording a reasonable assurance that withdrawals would be met whenever required by depositors who dealt with the Bank as customers and therefore as creditors, and not beneficiaries. The question whether this was the true view of the matter did not arise for decision, but the fact that their Lordships did not advert to it is an important consideration to the contrary. Of course, it may well be that no clear distinction was generally made between banks modelled on the mutual principles of Ruthwell and those administered by independent trustees after the fashion set in Edinburgh. Moreover, the rapid spread of savings banks had gone far to supply the social need which inspired them, and they had begun to assume the appearance of business institutions. Indeed much of the development must have already taken place to which the learned authors of the article on Savings Banks in the 11th edition of the Encyclopædia Britannica refer when they say (vol. xxiv., p. 244): - "The promotion of thrift, at the end of the 18th century an experiment of a few far-seeing individuals, was by the 20th century almost universally adopted, and was regarded practically as an adjunct to the institutions of every civilized community. Friendly societies, co-operative societies, trade societies and other agencies are all based on this same principle." Such changes must profoundly affect the purposes served by institutions and the motives from which they are administered, matters upon which the description of "charitable" greatly depends. But the development is uneven and uncertain. It should therefore perhaps not be surprising to find that in 1848 an infant child, who inherited a great name, was forthwith put in his ancestors' place as the president of such a savings bank, and that in 1869 on attaining full age he attended a meeting of trustees "considering the bank as a charity worthy of support" (In re Cardiff Savings Bank[23]). In 1862, however, the question was considered by the Judges. A fraudulent trustee of a savings bank was convicted under 20 & 21 Vict. c. 54, sec. 1, a provision which related only to trustees on some express trust created by deed, will, or instrument in writing, and made it a misdemeanour for any person being such a trustee "of any property for the benefit, either wholly or partially of some other person or for any public or charitable purpose" fraudulently to convert it to his own use. The prisoner was convicted upon the whole indictment, but one set of counts stated the trust as for a public purpose and another set as a trust "for the benefit of certain persons who had before then deposited the same" (i.e., the money misappropriated) "in a certain bank for savings." The conviction was considered by the Judges and after a second argument affirmed (Reg. v. Fletcher[24]). In the course of the argument prisoner's counsel said[25] that a public trust was synonymous with a charitable trust, but that here the object was not charitable, but merely the private benefit of the depositors, who were a definitely ascertained body, but he denied that they were cestuis que trustent and that they could "follow the trust property specifically, which they would be at liberty to do, if the defendant were really a trustee"[26]. The counsel for the Crown contended for a public trust: "Savings banks are regulated by various public Acts, and it is obviously for the benefit of the State that habits of saving should be encouraged"[27]. During the argument Willes J. referred to Holmes v. Henty[28] and said[29]: "Holmes v. Henty shows they are trustees under a trust for the benefit of the depositors." In delivering the opinion of the Judges Cockburn C.J. said[30]: - "I am of opinion that the conviction ... was right, and ought to be upheld. The first question is, was the defendant a trustee within the meaning of the 20 & 21 Vict. c. 54? It has been contended by Mr. Mathews that he was not; that, although he was called a trustee, yet the real relation existing between him and the depositors was that of debtor and creditor only; and that he was merely liable to an action at law, and to repay to each depositor the amount deposited by him with interest. I cannot concur in that view. I think that there was a trust here, namely, to receive the money and hold it for the benefit of the institution, and, so long as the money remained in his hands, to hold it entirely for the benefit of the depositors. I am disposed to think that it was not a trust for a public purpose. Although the institution is one of national concern, and it is for the public interest that the savings of depositors should be protected, yet it was not a public or charitable purpose. The word public in the Act must be understood to mean such a purpose as would be recognized as public in a Court of law, such as are the purposes of such institutions as are exempted from liability to the poor-rate. The trust here was for other persons. From the whole scope of the rules it is plain that the trustees do not hold the funds in their hands for their own individual benefit, but for the benefit of the depositors."
