Whether or not he had a point to make in the hearing, Smith did point out that more teams may begin to appeal charges now that the Rabada judgment has shown the match referee's verdict is not cast in stone.
Rabada successfully appealed against an International Cricket Council sanction for brushing the shoulder of Australia captain Steve Smith in the second Test, getting his punishment reduced from three demerit points to one.
Independent commissioner Michael Heron has overturned Kagiso Rabada's two-test cricket ban, clearing South Africa's spearhead to play the rest of the series against Australia. Asked whether he thought Rabada had made deliberate contact, Smith said: "It's not my place to make that judgment".
Instead, Heron, from New Zealand, found the world's top-ranked test bowler guilty of a minor level-one charge of conduct that was contrary to the spirit of the game, issuing a single demerit point and fine of 25 percent of his match fee.
"They've deemed the contact not to be deliberate and set the line in the sand of what is appropriate and what's not".
Steve Smith of Australia reacts during the 2018 Test Series match between South Africa and Australia at Sahara Kings Park Stadium in Durban, South Africa. "He had done it before and had five offences in 14 months".
It means the world's top-ranked bowler, fresh from man-of-the-match honours in the second test, will be steaming in during the match that starts in Cape Town on Thursday.
USA in talks over metals tariffs, says has tools to tackle China
The Trump administration is expected to unveil up to US$60 billion (S$79 billion) in new tariffs on Chinese imports by Friday. The EU has said it plans to impose safeguards but has not said how comprehensive they would be.
With the four-match Test series now locked at 1-1, Rabada's presence in the South African playing XI will only bolster their chances of taking a lead in Cape Town.
Was Gibson concerned that the Aussies would try and goad Rabada into earning another demerit point at Newlands and with it another ban for the fourth test at the Wanderers on March 30?
"We are pleased that he has been allowed to do that for the rest of the series". By contrast, Australia's batsmen have so far failed to score a single century in this series, and unless they can turn that trend around it is hard to see them halting South Africa's momentum. He was previously found guilty of inappropriate wicket celebrations on three occasions before this series and served a one-test ban in England past year. It made sense for him to appear as he was on the receiving end of Rabada's mid-pitch bump with his shoulder in Port Elizabeth.
He felt sorry for Crowe, whose finding that the deliberate and inappropriate contact was tossed out by fellow New Zealander Heron.
Disciplinary system is flawed.
Rabada is the fifth player in just two tests to be punished for misconduct. "The actions contravened the principle that a dismissed batsman should be left alone".
In quotes published on the Cricinfo website, Smith said about the decision: "The ICC have set the standard, haven't they?"
