Sending money to a fraudster does not automatically make your bank liable for your loss. That is the powerful legal message emerging from a landmark High Court decision that is set to reshape how businesses, consumers and financial institutions understand responsibility in Uganda’s rapidly growing digital economy.
In a judgment expected to influence future banking and commercial disputes, the High Court ruled that once a bank faithfully executes a customer’s authorised payment instructions and the funds reach the intended account, its legal duty is fulfilled. The bank cannot be required to compensate a customer simply because the transaction later turns out to be fraudulent.
The ruling, delivered by Hon. Justice Bernard Namanya in Stanbic Bank (Uganda) Ltd v Deus Kamunyu Muhwezi [2026] UGHCCD 221 (Civil Appeal No. HCT-00-CV-CA-0007-2022), overturned an earlier decision that had held Stanbic Bank liable for a customer’s financial loss arising from an international vehicle purchase. Beyond resolving a dispute that has stretched back to 2009, the judgment establishes a significant precedent on the boundaries of banking liability and reinforces the principle that commercial risk ultimately rests with the customer.
The dispute originated when Deus Kamunyu Muhwezi sought to purchase a motor vehicle from a Japanese dealer operating as Star Trade Japan. He instructed Stanbic Bank’s Makerere University branch to transfer USD 2,800 to the account of Katagawa Reiji at the Bank of Tokyo UFJ and paid a USD 15 processing fee.

While processing the transaction, a Stanbic Bank employee mistakenly entered the beneficiary’s name in both the sender and receiver fields of the bank’s internal processing system. Although the clerical error appeared on the payment documentation, the transfer itself was completed successfully, and the money reached the designated account.
The dispute arose after the overseas seller allegedly denied receiving the funds. Muhwezi requested proof of payment from Stanbic Bank, but because the confirmation reflected incorrect sender details, he declined to forward it to the seller. Instead, he sued the bank for negligence, arguing that the administrative error had caused his financial loss and seeking reimbursement together with damages.
The Chief Magistrate’s Court at Mengo initially agreed with Muhwezi, finding that Stanbic Bank had breached its duty of care and ordering it to refund USD 2,815 together with general damages.
However, the High Court reached a different conclusion after re-evaluating the evidence.
Justice Namanya found that records from the Bank of Tokyo Japan conclusively showed the USD 2,800 had been credited to the account specified by Muhwezi and later withdrawn by the beneficiary. The court therefore concluded that Stanbic Bank had carried out the customer’s instructions exactly as directed.
Although the bank had committed a clerical error when recording the sender’s particulars, the court held that the mistake was legally immaterial because it neither prevented nor altered the successful execution of the transfer. Instead, the loss arose from what appeared to be fraud committed by the overseas recipient rather than negligence by the bank.
In reaching his decision, Justice Namanya relied on the UK Supreme Court’s decision in Philipp v Barclays Bank UK plc, reaffirming the long-established principle that a bank’s contractual obligation is to execute lawful payment instructions not to judge whether those instructions are commercially wise.
“It is a basic duty of a bank under its contract with a customer who has a current account in credit to make payments from the account in compliance with the customer’s instructions. This duty is strict. Where the customer has authorised and instructed the bank to make a payment, the bank must carry out the instruction promptly. It is not for the bank to concern itself with the wisdom or risks of its customer’s payment decisions.”
The decision draws a clear legal distinction between operational negligence and commercial risk. A bank may be liable if its own actions misdirect funds or prevent a valid transaction from being completed. But where money reaches the exact account identified by the customer, responsibility for any subsequent fraud does not shift to the financial institution.
For businesses, the judgment serves as a timely reminder that due diligence cannot be outsourced to a bank. As international trade and digital payments become increasingly common, verifying suppliers, confirming banking details and assessing transaction risks remain the responsibility of buyers.

The High Court ultimately allowed Stanbic Bank’s appeal, set aside the lower court’s orders requiring the bank to refund the customer and pay damages, and directed each party to bear its own legal costs.
The ruling is expected to become an important reference point in Uganda’s banking and commercial law, reinforcing a simple but significant principle: banks are responsible for moving money accurately, not guaranteeing that every deal their customers enter into is legitimate.
