 Owners themselves often had little or no money, since they had fallen victim to negative equity, so mortgage lenders would pursue a valuer instead to recover some losses.In the South Australia case, a valuer had (in breach of an implied term to exercise reasonable care and skill) negligently advised his client bank that property which it proposed to take as security for a loan was worth much more than its actual market value.The question was whether he should be liable not only for losses attributable to the deficient security but also for further losses attributable to a fall in the property market.
