The chief of the Corruption and Crime Commission criticised the watchdog's critics yesterday and accused its parliamentary oversight committee of a lack of procedural fairness.
As he sought to defend his agency's reputation amid attacks from senior legal and police figures including Police Commissioner Karl O'Callaghan, CCC Commissioner Roger Macknay clashed with the chairman of the joint standing committee on the CCC, Liberal Nick Goiran.
Called before the committee yesterday for routine questioning on the agency's annual report, Mr Macknay demanded the CCC be allowed to respond in a public hearing to attacks on the agency's handling of complaints against police.
Though he did not name names, Mr Macknay said evidence to the committee's inquiry into how the CCC dealt with complaints about police was inaccurate, wrong and offensive.
The committee has heard criticism of the CCC from Mr O'Callaghan, who said its handling of the complaint against the police officers involved in the Kevin Spratt tasering affair was entirely disingenuous and bizarre.
Barrister Ron Davies, who represented Mr O'Callaghan in the CCC's investigation of his travel expenses, said the CCC's investigators were "bad" and "zealots".
Mr Macknay said procedural fairness demanded the CCC be allowed to rebut its critics.
"I was dismayed at some of the evidence given," he said. "Some of it was inaccurate, some of it was wrong, some of it is really offensive.
"I am privileged, I can come along and complain.
"But there are 150 commission officers who simply have . . . to wear that sort of criticism in the media. And it does become wearing over a period of time."
The committee's report is due to be handed down next Thursday.
Mr Macknay said he was concerned it was too late for the committee to consider the CCC's evidence with an open mind.
He suggested the committee had almost concluded its views without hearing from the CCC.
"I greatly regret it is necessary for me to suggest to members of the committee that in fact this whole process has miscarried," Mr Macknay said.
"I must protest in the strongest terms that the commission is being denied procedural fairness by this committee."
Mr Goiran said: "I understand that is your view, Commissioner. It is not the committee's view.
"The CCC does not know the current status of the drafting of this report - it's a matter for the committee. The committee is not about to reveal its deliberations."
The committee later issued a statement saying the CCC could give its rebuttal in a specially scheduled hearing tomorrow.
