Cricket South Africa (CSA) have challenged the International Cricket Council (ICC) to clarify their stance on ball tampering.
Proteas captain Faf du Plessis was found guilty of the violation after shining the ball with saliva from a sweet in the Hobart Test.
Du Plessis had to forfeit his entire match fee and received three demerits – one short of a ban.
Footage has emerged showing India captain Virat Kohli doing the same thing this week in their Test against England.
Now CSA CEO Haroon Lorgat wants the ICC to be clear and consistent about shining the ball.
Lorgat says: “We’ve advised Faf to reserve his position with regard to the match referee’s finding and wait for the full reasons of his decision before deciding his next step.
“In fairness to both him and the ICC, this is an unprecedented case involving unique issues of policy, science and performance that need to be carefully considered at the highest levels of the game.
“There are also issues relating to fair and just process, interpretation of the rules, and… the consistent application of the Code of Conduct that needs to be considered.
“CSA believes that the laws of the game do not currently define the term ‘artificial substance’, leaving room for inconsistent application of the rules.
“For instance, the laws currently prevent the use of ‘artificial substances’ to polish the ball, yet artificial cotton fibres from playing kit can be used to shine the ball.
“Players also regularly chew gum when applying saliva to the ball, or ingest sugary drinks and sweets during short breaks in play before shining the ball. No action is taken in such circumstances by the umpires.”
