Former South Africa director of cricket Graeme Smith has been cleared of racism allegations against him by two independent arbitrators.

Smith was accused of racial bias against black leadership at Cricket South Africa (CSA), discrimination against Proteas wicketkeeper Thami Tsolekile and unfair racial treatment surrounding the appointment of Mark Boucher over Enoch Nkwe in 2019.

The former Proteas skipper was under review by Dumisa Ntsebeza SC after CSA's Social Justice and Nation-Building (SJN) process, with Ntsebeza unable to conclude on "definite findings" in December 2021.

The initial report criticised Smith and former captain AB de Villiers for selection decisions, which it said were prejudicial towards black players, allegations the pair both denied.

That led to further formal processes, with two independent arbitrators Ngwako Maenetje SC and Michael Bishop reviewing the case, before Smith was cleared of the allegations of racism.

Smith, who held the CSA director role between 2019 and 2022 before his contract ended in March this year, has also been reimbursed his costs by CSA on the advice of the arbitration.

Lawson Naidoo, chairman of the CSA Board, said after the decision: "The manner in which these issues have been dealt with and resolved by the arbitration proceedings confirms CSA's commitment to deal with the SJN issues in a manner that treats them with utmost seriousness but also ensures fairness, due process and finality.

"Now that finality on these processes has been reached, it is appropriate to recognise the extraordinary contribution that Graeme has made to South African cricket, first as the longest-serving Test captain in cricket history and then as director of cricket from 2019 to 2022.

"His role as director has been critical in rebuilding the Proteas men's team in particular and has laid a solid foundation for his successor.

"We fully appreciate that after his time as director, Graeme wants new challenges in the commercial and cricket worlds.

"He has a long career ahead of him and we very much hope that he will still work in the cricket world in appropriate capacities going forward."

CSA apologised for the unwarranted public disclosures of Smith's personal information, including his remuneration, during the SJN process, as they thanked the 41-year-old for his efforts in charge.

Pholetsi Moseki, who is CSA's chief executive, added: "On behalf of the executives, staff and players at CSA, I would like to thank Graeme for all that he did as the director of cricket.

"He put up his hand at a particularly tumultuous period for CSA and he has often gone beyond his contracted duties to assist CSA during his term."
