The International Cricket Council on Monday issued a "final warning" to the Pakistan Cricket Board and captain Inzamam-ul Haq for making "unnecessary and inappropriate" public comments in the wake of the Oval Test fiasco.

ICC [Images] chief executive Malcolm Speed [Images] said he is disappointed by some of the comments that had appeared in the media and would not hesitate to "lay charge" if further comments are made ahead of the disciplinary hearing of the Pakistan skipper later this month.

"I have been very disappointed by some of the public comments that have been made by members of the PCB, team management and captain Inzamam-ul Haq following the Oval Test," Speed said.

Speed said such comments could be seen as prejudicial to the pending code of conduct hearing.

"Over the course of the last two weeks there has been a stream of unnecessary and inappropriate public comment from the PCB, much of which could be seen as prejudicial to the pending code of conduct hearing.

"We have in place a fair and independent process for dealing with the matters that arose out of the Oval Test and all concerned parties will have an opportunity to present their evidence during the hearing later in September," he said.

Speed said the Pakistani team management had breached the ICC Code of Conduct which bars public criticism of a match related incident or official.

"Ahead of this hearing it is wholly inappropriate for officials or players to comment on the issues that will be addressed, particularly as the ICC Code of Conduct includes a specific offence of 'public criticism of, or inappropriate comment on, a match-related incident or match official."

Speed warned that they would take action if such comments are not stopped immediately, adding: "the acute international diplomatic and political sensitivity of this issue has persuaded me not to lay a charge to date but despite the exceptional circumstances I will not hesitate to lay a charge should further inappropriate public comments be made ahead of the hearing."

Speed confirmed he had raised the matter twice in the past ten days with PCB chairman Shaharyar Khan and he had also asked ICC match referee Mike Procter to do likewise with the Pakistan captain and team management.

"There will be plenty of opportunity for Pakistan to put its side of the story in the fair environment of the code of conduct hearing. That is the appropriate forum for its views on these matters," he added.

The details of the timing and venue of the code of conduct hearing will be announced in due course, the release said.
