The Supreme Court has blocked Chancellor Rachel Reeves' bid to step in amid the controversial car loan case and stop lenders potentially being forced to shell out billions in compensation.
The UK's highest court is set to decide in April whether lenders should have made it clearer to customers exactly how much commission they were making from the selling of loans.
April's hearing is comes after lenders appealed against a ruling last year that they should have been clearer.
The Treasury had attempted to weigh in over fears the ruling could make it much more difficult for people to obtain car loans.
But the court has now blocked such a move, a decision the Treasury told the BBC it respects.
The Financial Conduct Authority (FCA) banned deals in 2021 involving the dealer receiving a commission from the lender, based on the interest rate charged to the customer.
The ban was introduced as the FCA said such deals provided an incentive for a buyer to be charged a higher-than-necessary interest rate.
Now, affected customers could potentially be paid compensation.
