Cape Town - Knights all-rounder Johan van der Wath has been banned for one Sunfoil Series match following a Cricket South Africa (CSA) disciplinary hearing while Cape Cobras captain Justin Ontong is eligible to continue playing for his franchise pending the results of a ball test being carried out in Australia.CSA Disciplinary Commissioner Professor, Rian Cloete, has made the following rulings in terms of the CSA Code of Conduct:"Mr Van der Wath did not attend the disciplinary hearing, but wrote a letter of apology (dated 14 January 2013) for his behaviour. The hearing proceeded in absentia within the terms of clause 126.96.36.199 of the Code."The evidence of the match report is, therefore, not in issue and the complaint is established. I find Mr Van der Wath guilty of a breach of clause 6.3.1 (f) of the Code of Conduct in that he used language that is seriously obscene, offensive or insulting towards another participant."I take into account the fact that Mr Van der Wath has not sought to evade responsibility for his conduct, that he had admitted the offence and offered his sincere apology in writing. "Having taken all factors into account, it is important that an effective penalty be imposed. In the circumstances I am satisfied that the appropriate penalty in respect of this offence, which is a level 2 offence, is a suspension for one four day match but without the need, in addition to impose a fine."The following order was made:1. Van der Wath is ineligible for selection for the forthcoming Sunfoil Series Match against the Warriors due to be played from 17 - 20 January 2013 at Chevrolet Park, Bloemfontein.As far as the complaint against Ontong is concerned, Cloete confirmed that the ball in question will be sent to Kookaburra, in Victoria, Australia for examination and testing.The matter will, therefore, be held in abeyance pending the results of the testing and Ontong is eligible for selection until further notice. Ontong was in trouble after his side was accused of ball tampering in their clash against the Lions at Newlands last weekend.
