Phillip alleged Barclays owed her a duty to ignore her instructions if the bank had reasonable grounds to suspect she was being defrauded.
"Where the customer has authorised and instructed the bank to make a payment, the bank must carry out the instruction promptly," he said.
"It is not for the bank to concern itself with the wisdom or risks of its customer's payment decisions."
James Levy, a partner at law firm Ashurst, said the onus was on customers to ensure payment instructions were bona fide.
The Supreme Court, however, allowed Philipp to pursue an alternative case against Barclays on the grounds that the bank breached its duty by failing to take adequate steps to recover the money transferred to the UAE.
