LONDON (Agencies) - The Crown Court in London has dismissed the appeal of banned Pakistan cricketers Salman Butt, M Asif and M Aamir to dismiss their corruption case in a preliminary hearing. The trio, who were found guilty of spot-fixing by the International Cricket Council and are serving a minimum five-year ban, had filed an appeal asking the court to dismiss criminal charges that the Crown Prosecution had levelled against them. Aamir and Asif attended the hearing, while his lawyer represented Butt. The trio was caught in a sting operation carried out by the British tabloid News of The World during Pakistan's tour of England last year.
