Banned fast bowler Muhammad Asif has filed an appeal against his five-year ban by the ICC with the Court of Arbitration for Sport (CAS) in Switzerland. The ICC anti-corruption tribunal had banned Asif and two other Pakistani cricketers, Salman Butt and Muhammad Aamir in February last year after finding them guilty of involvement in spot fixing during the fourth Test against England at Lord's in 2010. "The appeal filed in the CAS against the ICC ban is founded upon multiple grounds that include the argument that the ICC tribunal breached its own proceedings and in other ways infringed fundamental human rights to which Asif is entitled," a spokesman for the legal firm representing Asif said. "In such a situation the ICC ban is not only flawed, it could also be unlawful," he added. The spokesman said the CAS will now set a date for the hearing.
