A recent Court of Appeal ruling has raised the possibility of delayed compensation payouts for car buyers mis-sold finance agreements linked to undisclosed commission payments. The Financial Conduct Authority is considering allowing dealers more time to handle complaints, which may postpone compensation that could total billions. Previously banned commission practices, deemed unlawful without customer consent, have been scrutinized following a test case involving a buyer who was unaware of a significant commission added to his loan. Analysts estimate potential payouts could reach £16 billion, prompting lenders to halt new deals.
