The Supreme Court has told lender Westpac New Zealand it was wrong to withhold client funds amid suspicions over where the money was going and it will have to pay interest and costs.
The full Supreme Court bench of Chief Justice Sian Elias and Justices Peter Blanchard, Andrew Tipping, John McGrath and William Young unanimously dismissed Westpac's appeal and ordered it to pay $15,000 plus disbursements to Hamilton accounting firm Map & Associates.
The bank was trying to avoid costs and interest after asking the accounting firm to get a court order in 2008 to release funds held on behalf of investors in a Bolivian bank when it got nervous about the proposed transfer of funds.
Westpac argued that the potential for helping acts of dishonesty was enough to justify its actions, though the court ruled that was too low a benchmark.
"Acceptance of the bank's submission would leave the customer bearing the loss when there was in fact no problem with the customer's instructions, but the bank, albeit reasonably, suspected or believed there was," Justice Tipping said when delivering the judgement.
