PCB didn't appeal ban

The Pakistan Cricket Board (PCB) has dismissed reports that it had filed any appeal on behalf of banned Pakistani pacer Mohammad Aamer with the International Cricket Council (ICC).
"We have filed no formal appeal as such. Yes we have written to the ICC about the case in light of the observations made by its anti-corruption tribunal regarding the existing anti-corruption code of conduct laws under which Salman Butt, Mohammad Asif and Aamer have been penalised," an official said.
The official made it clear that the right to appeal against their bans only rested with the three players not with the board.
