Former Pakistan spinner Danish Kaneria says he is "not guilty" after being banned for life in 2012 by the England and Wales Cricket Board for his part in a spot-fixing scam.
The 33-year-old, who was punished for introducing then Essex team-mate Mervyn Westfield to illegal bookmakers, says he has been discriminated against.
Westfield was jailed for four months after receiving £6,000 for agreeing to concede 12 runs during an over of a one-day game against Durham in 2009.
Kaneria was never charged, but his role in suggesting and organising the spot-fixing plan, as well as his influence over Westfield - acknowledged during the latter's trial - saw the spinner receive a lifetime ban, which applies worldwide.
Kaneria is attempting to have his ban overturned, filing a case against the ECB at the High Court's Commercial Court, starting on 11 April.
