Mackinnon (Millar's Factor) v. Knox and Others (Millar's Trustees)

Factual and Procedural Background

A draper in The City died in 1863 leaving an estate held in trust. The trustees (“Appellant”) were to pay the widow an annuity of £400 and divide any residue among seven children (“Respondent” and other beneficiaries). The deed conferred very broad investment powers, permitting the trustees to invest “on such securities, heritable or personal, as they should think proper.”

In 1874 the eldest son (“Family Member A”) purchased the business premises from the trust for £25,000. After paying £13,000 he asked the trustees to lend him the remaining £12,000. As security he offered: (1) the premises already burdened by a £17,000 first bond, (2) other heavily-encumbered properties, (3) a life-policy worth less than £500 on surrender, (4) a one-seventh share of £10,000 set aside for the widow’s annuity, and (5) the personal guarantee of his father-in-law (“Family Member B”). The trustees accepted the offer without informing the beneficiaries; one beneficiary protested in writing but was ignored.

In 1884 both Family Member A and Family Member B were sequestrated and the prior bondholders entered into possession, rendering the trust’s security worthless. The beneficiaries sued the trustees for the resulting loss. The Lord Ordinary and the Second Division of the Court of Session held the trustees personally liable. The trustees appealed to the House of Lords; the present opinion dismisses that appeal.

Legal Issues Presented

1. Whether the trustees breached their fiduciary duty by lending £12,000 of trust funds on security that was manifestly inadequate.
2. Whether wide investment powers in the trust deed, coupled with an indemnity clause, exempt the trustees from personal liability for the loss.
3. The proper standard of care for gratuitous trustees: the objective “ordinary prudent person” test versus each trustee’s personal habits in private affairs.
4. Whether trustees can rely on advice from a legal adviser who simultaneously acted for the borrower to shield themselves from liability.

Arguments of the Parties

Appellant's Arguments

• The trust deed expressly authorised investment on “such securities…as they may think proper,” thereby validating the loan.
• An indemnity clause stating that trustees “shall not be liable for omissions, errors, or neglect of management” protected them from any personal liability.
• As gratuitous trustees, their conduct should be measured by the care each uses in personal affairs, not by an abstract reasonable-person standard.
• The transaction was carried out bona fide upon the advice of the trust’s solicitor, so any error was an excusable error of judgment.

Respondent's Arguments

• The securities were “unsubstantial and insufficient,” making the loan a breach of trust and an imprudent investment.
• An indemnity clause cannot shield trustees from liability for gross negligence (culpa lata) or conduct lacking bona fides.
• The trustees favoured Family Member A over other beneficiaries and ignored timely protests, violating their duty of impartiality.
• Reliance on conflicted legal advice cannot absolve trustees who knowingly expose the trust to risk.

Court's Reasoning and Analysis

All members of the appellate panel—Judge Chancellor, Judge Watson, Judge Fitzgerald, and Judge Macnaghten—agreed that the lower-court findings of fact were “very satisfactorily supported by the evidence.” Key elements of the analysis were:

• Nature of the loan. The £12,000 was not a genuine investment but an “accommodation” enabling Family Member A to complete his purchase; the trustees knew or should have known he could not otherwise pay.
• Adequacy of security. The properties were already heavily encumbered; the margin of value was minimal and ultimately illusory. Supplementary securities (life-policy, annuity share, personal guarantees) were likewise of little worth. Accepting them amounted to gross negligence.
• Power to invest. A power to lend on “personal” as well as “heritable” security does not entitle trustees to take worse security when better is available; it must be exercised to preserve capital for beneficiaries.
• Indemnity clause. Scottish law does not allow such clauses to protect trustees from liability stemming from culpa lata, gross negligence, or conduct inconsistent with bona fides; therefore, the clause was inapplicable.
• Standard of care. The court rejected the proposition that a trustee’s liability is measured by the care he uses in his own affairs. The proper test is that of an “ordinary prudent person” (bonus paterfamilias).
• Reliance on conflicted advice. Trustees cannot discharge their fiduciary duty by relying on advice from an adviser who also represents the borrower; doing so exacerbates, rather than excuses, the breach.
• Continuation of the loan. Allowing the funds to remain on the same inadequate security for a decade, despite beneficiary protests, aggravated the breach; at minimum the trustees should have sought repayment or reinvestment.

Holding and Implications

Appeal dismissed; interlocutors affirmed. The trustees are personally liable to make good the loss and must pay the costs of the appeal.

Implications: The decision underscores that (1) even the widest investment powers do not authorise imprudent or conflicted transactions, (2) indemnity clauses do not protect against gross negligence or bad faith, (3) trustees are judged by an objective standard of ordinary prudence, and (4) reliance on advisors who suffer a conflict of interest offers no defence. The ruling primarily affects the parties and reiterates established fiduciary principles without creating new precedent.
