Bartlett v Barclays Bank Trust Co Ltd (No. 2) [1980] 1 Ch 515 in an English trusts law case. In it Brightman J gave a comprehensive discussion of the duties of trustees in connection with companies whose shares are part of the trust property. Although it is common to hear lawyers refer to "the rule in Bartlett v Barclays Bank", the case only restated law that had been accepted since Speight v Gaunt. Facts Barclays Bank was the sole trustee of the Bartlett trust, set up by Sir Herbert Bartlett. The sole asset of the trust was 99.8% of the issued shares in the family company. On the company board were two surveyors, an accountant and a solicitor. The trustee appointed none. In an attempt to raise cash, the trust appointed merchant bankers to consider taking the company public. The bankers advised that a public offering would be much more successful if the company expanded its business from managing property to developing property as well. Barclays Bank as trustee agreed to this policy (so long as the income available to the beneficiaries was not affected). The board then embarked on speculative developments, one of which ended in disaster when planning permission could not be obtained for a large development (the Old Bailey project), and the trust suffered a significant loss. Judgment Brightman J held that the bank, as trustee, had not discharged its duty as trustee in failing to supervise the new ventures of the company. He held that, given the size of the shareholding, the bank should have obtained the fullest information on the conduct of the business, and it was not sufficient to rely merely on the supply of information that they received in the ordinary course as a shareholder. Their defence, that they honestly and reasonably believed the board of directors to be competent and capable of running the business, was rejected. The court reiterated older propositions as to the duty of trustees, "to conduct the business of the trust with the same care as an ordinary prudent man of business would extend to his own affairs." However, the implication was that where a prudent man of business holds the majority of shares in a company, he would actively engage himself in the company's undertakings rather than leaving it to the board. Brightman J distanced the court from suggestions made in Re Lucking's Will Trusts [1968] 1
