South Australia Asset Management Corporation v York Montague Ltd [1997] AC 191 (“SAAMCo”)

Citation

• Full case name: South Australia Asset Management Corporation v York Montague Ltd, heard with Banque Bruxelles Lambert SA v Eagle Star Insurance Co Ltd
• Neutral citation: [1996] UKHL 10
• Reported at: [1997] AC 191
• Court: House of Lords
• Judgment: 1996
• Leading speech: Lord Hoffmann
• Subject: scope of duty; causation and remoteness; valuers’ and lenders’ claims

Facts

The appeals arose out of the property crash of the early 1990s. Lenders had advanced money against commercial and residential property on the strength of valuations which were negligently high. The borrowers defaulted. By the time the security was realised the market had fallen sharply, so the lenders’ losses were far greater than the amount by which the valuations had been wrong.

The lenders sued the valuers for the whole of the shortfall, arguing that but for the negligent valuations they would never have lent at all and would have suffered none of the loss.

Issue

Where a professional gives negligent information which causes a client to enter a transaction, is the professional liable for all the foreseeable loss flowing from the transaction, or only for the loss attributable to the information being wrong?

Decision and ratio

Lord Hoffmann framed the question as one about the scope of the duty. A defendant is not liable for all consequences of his negligence that satisfy the “but for” test; he is liable for the consequences of the matters in respect of which he owed a duty of care.

He introduced the parable that has been quoted in every subsequent case on the subject, at page 213:

“A mountaineer about to undertake a difficult climb is concerned about the fitness of his knee. He goes to a doctor who negligently makes a superficial examination and pronounces the knee fit. The climber goes on the expedition, which he would not have undertaken if the doctor had told him the true state of his knee. He suffers an injury which is an entirely foreseeable consequence of mountaineering but has nothing to do with his knee.”

The distinction Lord Hoffmann drew was between a professional who supplies information for the purpose of enabling someone else to decide on a course of action, and one who advises on whether to take that course of action at all. A valuer is usually in the first category. He supplies one input into the lender’s decision, and is responsible for the consequences of that input being wrong — ordinarily the difference between the negligent valuation and the true value — not for the consequences of the transaction as a whole, including the fall in the market.

Later development

SAAMCo has been applied and refined repeatedly. In BPE Solicitors v Hughes-Holland [2017] UKSC 21 the Supreme Court reviewed the authorities and confirmed the information and advice distinction, while cautioning that categorisation is fact-sensitive and that neither category is the “normal” one.

In Manchester Building Society v Grant Thornton UK LLP [2021] UKSC 20 the Supreme Court restated the exercise in terms of the purpose for which the advice was given, treating the scope of duty question as the organising principle rather than a mechanical cap.

Why it matters for insurance

SAAMCo is one of the most valuable defences in professional indemnity. It is the reason a claim pleaded at the full amount of a client’s losses is often worth a fraction of that figure, and it is a principal driver of reserving on surveyors’, valuers’, accountants’ and solicitors’ books.

For an insured firm the practical lesson is about the retainer. What determines the outcome is the range of matters for which the professional assumed responsibility, and that is established by the engagement letter, the scope of works and the terms on which the report was issued. Firms that write scope clearly, and keep the file that proves it, defend claims for a great deal less than firms that do not.

For brokers it is a reminder that a notification should describe the alleged breach and the client’s actual loss separately. The two are frequently very different numbers, and the difference is often the difference between a claim within the excess and a claim that erodes the limit.

Frequently asked questions

What is the SAAMCo principle?

That a professional adviser is liable only for the loss that falls within the scope of the duty undertaken. Where the adviser supplies information for the client to use in reaching a decision, the adviser answers for the consequences of the information being wrong, not for all the consequences of the client entering into the transaction.

Does SAAMCo mean a negligent valuer pays nothing?

No. It means the valuer normally pays the amount attributable to the valuation being wrong rather than the whole of the lender's loss. Where a market fall has magnified the shortfall, the difference between those two figures can be very large.

Why does the engagement letter matter so much?

Because the scope of the duty is what the principle turns on. The engagement letter, scope of works and the terms on which a report is issued define the range of matters for which the professional assumed responsibility, and that in turn defines how much of the client's loss is recoverable.
