Cook was overlooked for the under-80 kilograms place at the Games despite retaining his European title earlier this year.
The world No.1 maintained the decision to select Muhammad was flawed, but after the British Olympic Association (BOA) ruled there was insufficient new evidence for British Taekwondo to be forced to reopen their selection process and also did not allow Cook to take his case to the Court of Arbitration for Sport (CAS), Cook reluctantly dropped his appeal and decided against taking it to the High Court.
