A bid by Sports Direct to get Newcastle United to sell next season's shirts in its shops has failed.
The Competition Appeals Tribunal unanimously rejected the firm's request for an immediate injunction to stop the club's exclusive deal with rival company JD Sports.
Sports Direct, which is run by former Newcastle owner Mike Ashley, had alleged competition would be damaged by the move.
The firm will still be able to take the club to court over the matter at a later date, if it wishes.
Sports Direct lawyers had previously said preventing the "home of football supplies" from selling cheaper shirts would harm fans.
