Hair is suing the International Cricket Council (ICC) for racial discrimination.

Together with fellow umpire Billy Doctrove of the West Indies, he took a joint decision to penalise Pakistan for ball-tampering on the fourth day of the fourth Test against England at The Oval in August last year.

So enraged were Pakistan by this decision they refused to take the field immediately after tea.

By the time they were ready to play the umpires ruled they had forfeited the match - the first and so far only time this has happened in the now 130 years of Test cricket.

Hair, 55, says since taking that decision the ICC have caved into pressure, primarily from cricket's Asian bloc (India, Pakistan, Sri Lanka and Bangladesh), which has seen him denied the chance to continue to stand in major international matches.

Hair explained why he accused Pakistan of ball-tampering, claiming that he felt the rough state of the ball "had been accelerated by human intervention".

He impressed upon the three-man tribunal panel that he had taken joint decisions throughout the Test with Doctrove.

"I was surprised by how much roughing up of the ball there had been," Hair told the tribunal. "There were quite a few scratch marks on it."

The burly Australian decribed how the match ended.

"Doctrove called time and I removed the bails at my end," signalling that their decision was taken in unison. He also said that "the abuse I received from Pakistan players continued unchecked by the ICC."

Hair's lawyer Robert Griffiths told the tribunal that Malcolm Speed, the chief executive of the ICC, wanted fellow Australian Hair to continue to stand in Tests and One-Day Internationals, but Pakistan and India were opposed.

"So he remained on its elite panel but he has suffered both personally and financially," Griffiths said.

"The ICC bowed to the racially discriminatory pressure that was brought to bear on it by the Asian bloc and ICC Board member countries. That has traumatised the world of cricket.

"The Asian bloc is dominant in cricket and sometimes it uses that dominance inappropriately. Everyone knows it, but most are afraid to say so," said Griffiths.

"A fundamental issue is whether this was done to save Pakistan's reputation and, or, to teach a lesson to a white Australian and any other umpires who dare take similar action."

Griffiths also claimed that there had been a "Watergate" style cover-up of an ICC Board meeting last November.

Part of a tape-recording of this meeting, attended by Sir John Anderson (New Zealand) Peter Chingoka (Zimbabwe) and Dr Nasim Ashraf (Pakistan) at which it was decided that Hair should not continue to umpire at the highest level, had gone missing, he said.
