In the confines of a small room at The Oval, Darrell Hair and Inzamam-Ul-Haq sat preparing to give evidence at the Pakistan cricket captain's disciplinary hearing on Wednesday.

The two main protagonists in the International Cricket Council's inquiry into last month's ball tampering row were seated quite close to each other in a gallery crammed with match officials, team representatives and legal advisers.

At a table facing them and presiding over the hearing was ICC chief referee Ranjan Madugalle.

Hair, the Australian umpire who emerged from five weeks of seclusion at his English home to give evidence, made a hasty entrance to The Oval - the scene of the controversy on August 20.

As he walked through the Alec Stewart Gates, Hair did not stop to talk to the waiting media, saying only: "No comment - good to see you all."

Inzamam arrived shortly before him, driving through the gates accompanied by Pakistan coach Bob Woolmer.

Also at the hearing was Hair's West Indian colleague Billy Doctrove.

The pair awarded the fourth Test to England after Inzamam refused to bring his team out after tea.

It was the first forfeit in 129 years of Test cricket.

In the previous session Hair and Doctrove had changed the ball and awarded a five-run penalty to England after informing Inzamam that they believed the ball had been altered illegally.

Inzamam, who denies that he or any of his players tampered with the ball, faces two charges under the ICC code of conduct - changing the condition of the ball and bringing the game into disrepute.

If found guilty of the first charge, he faces a fine of between 50 and 100 per cent of his match fee and/or a ban of one Test match or two one-day internationals.

The second charge carries a penalty of a ban between two and four Tests or four to eight one-dayers.

In Wednesday's edition of Britain's The Guardian newspaper, Inzamam said his conscience was clear.

"Definitely, I did feel some pressure. But inside I resolved that I had done nothing wrong and was satisfied with my actions," he said.

Madugalle will consider testimony and written statements from witnesses.

He has 24 hours from the end of the hearing to deliver a verdict, which will then be made public by the ICC.

Hair has not officiated at any level since the incident and in the aftermath it emerged that he had asked the ICC for US$500,000 (A$665,000) in exchange for his immediate retirement.

He subsequently withdrew the offer and has said he stands by his decisions on the field.
