Pakistan’s Supreme Court wants an explanation from cricket authorities about a life ban on former captain Salim Malik for his alleged involvement in match-fixing, an official said.The court is hearing an appeal by 43-year-old Malik, who now lives a secluded life in Lahore, against the ban imposed by the Pakistan Cricket Board (PCB) in May 2000. Lower courts have rejected the case. “The PCB should explain on what grounds Malik was banned for life. Courts give a period of life sentences and the PCB must tell under which law Malik is banned from playing cricket for all his life,” said the court in its remarks, quoted by assistant registrar Basheer Janjoa.
