Chris Venturas sent a letter to the ICC complaining about the way an aborted hearing was conducted in Harare last month.

But chief executive Malcolm Speed said it was a "schoolboy attempt to manipulate public opinion."

The ICC will study a report on the case at a meeting this weekend.

It was produced by South African judge Steven Majiedt and India's solicitor general Goolam Vahanvati after studying written submissions.

Their attempt to hear evidence from witnesses came to nothing after they were unable to resolve an argument about procedures.

Venturas, who represents a group of white former Test players, had argued the presence of ZCU administrators Ozias Bvute and Max Ebrahim, and Mashonaland Cricket Association chairman Tavengwa Mkuhlani would intimidate witnesses.

He subsequently sent a letter to Speed about the matter, which was also leaked to The Guardian newspaper.

In his response, Speed said: "I am dismayed that much of your concern now seems to be about allegations, witnesses or evidence that you have failed to disclose.

"Clearly, this material should have been in your written submission to allow both the panel and the Zimbabwe Cricket Union to understand the nature of the allegations and what evidence there was to support them.

"If you have failed in your obligation to provide this material, it is not the fault of the Panel or the responsibility of the ICC. "

He added: "What is clear....is that both parties made the hearing unnecessarily difficult and I note in particular the concerns they expressed about your conduct and the impact it had on allowing the proceedings to continue."
