South Australia Asset Management Corp v York Montague Ltd [1997] AC 191

Three appeals concerning negligent property valuations provided to lenders. The House of Lords held that a valuer's liability is limited to the consequences of the information being wrong, not all losses flowing from the transaction. This case established the 'SAAMCO principle' distinguishing between advice and information duties.

Facts

Three conjoined appeals arose from negligent property valuations provided to lenders. In each case, lenders had advanced money secured against properties that were overvalued by professional valuers. The common features were: (1) the lenders would not have lent had they known the true property values; and (2) a subsequent fall in the property market significantly increased the lenders’ losses.

The lenders advanced £11m on property valued at £15m, when the true value was £5m. The property was later sold for approximately £2.5m.

United Bank of Kuwait Plc v Prudential Property Services Ltd

The lenders advanced £1.75m on property valued at £2.5m, when the correct value was between £1.8m and £1.85m. The property was sold for £950,000.

Nykredit Mortgage Bank Plc v Edward Erdman Group Ltd

The lenders advanced £2.45m on property valued at £3.5m, when the correct value was approximately £2m. The property was sold at auction for £345,000.

Issues

The central question was: what is the extent of liability of a valuer who has provided a lender with a negligent overvaluation of property offered as security for a loan? Specifically, should the valuer bear all foreseeable losses flowing from the transaction, including those caused by market falls, or only losses attributable to the valuation being wrong?

Judgment

Lord Hoffmann delivered the leading judgment with which all other Law Lords agreed. He held that before considering the measure of damages, it is necessary to determine the scope of the duty of care and the kind of loss for which compensation is available.

“It is never sufficient to ask simply whether A owes B a duty of care. It is always necessary to determine the scope of the duty by reference to the kind of damage from which A must take care to save B harmless.”

Lord Hoffmann drew a crucial distinction between a duty to provide information and a duty to advise:

“If the duty is to advise whether or not a course of action should be taken, the adviser must take reasonable care to consider all the potential consequences of that course of action. If he is negligent, he will therefore be responsible for all the foreseeable loss which is a consequence of that course of action having been taken. If his duty is only to supply information, he must take reasonable care to ensure that the information is correct and, if he is negligent, will be responsible for all the foreseeable consequences of the information being wrong.”

A valuer provides information upon which the lender decides whether and how much to lend. The valuer is not responsible for all consequences of the transaction, only for the consequences of the information being inaccurate:

“I think that one can to some extent generalise the principle upon which this response depends. It is that a person under a duty to take reasonable care to provide information on which someone else will decide upon a course of action is, if negligent, not generally regarded as responsible for all the consequences of that course of action. He is responsible only for the consequences of the information being wrong.”

Lord Hoffmann rejected the Court of Appeal’s distinction between ‘no-transaction’ and ‘successful transaction’ cases as unprincipled.

Implications

This decision fundamentally reshaped the law on professional negligence liability, particularly for valuers and other information providers. The ‘SAAMCO principle’ limits damages to the consequences of the information being wrong, effectively capping liability at the amount of the overvaluation rather than extending to all losses from market movements.

The case established that:

• A duty of care must be defined by reference to the kind of damage from which the defendant must save the claimant harmless
• Information providers are liable only for consequences of inaccurate information, not all consequences of reliance on that information
• The distinction between ‘information’ and ‘advice’ cases determines the scope of liability
• Market falls are generally outside the scope of a valuer’s duty unless the overvaluation exceeds the fall

This principle has been applied across professional negligence cases and remains a cornerstone of English tort law regarding the scope of duty.

Verdict: The appeal in South Australia Asset Management Corporation v York Montague Ltd was dismissed as the whole loss fell within the scope of the defendants’ duty. The appeals in United Bank of Kuwait Plc v Prudential Property Services Ltd and Nykredit Mortgage Bank Plc v Edward Erdman Group Ltd were allowed, with damages limited to the difference between the negligent valuation and the correct value of the property.
