Attorney General John Quigley goes to the "Lawyer X" case

Attorney General John Quigley wants to know if the WA police have ever used defense lawyers to secretly speak to their clients.

He wrote to police minister Michelle Roberts asking her to "seek insurance" from commissioner Chris Dawson that WA's lawyers never acted as police informants and passed on confidential information to law enforcement agencies.

While the fallout from Victoria's "Lawyer X" royal commission resonates through state police forces, Mr. Quigley has moved swiftly to make sure that WA is not involved in the scandal.

The investigation is examining the relationship between the Victorian police and lawyer X, a well-known lawyer from Melbourne who represented some of the nation's most famous gangland figures, including Tony Mokbel and Carl Williams.

Lawyer X is believed to have worked as a police informant for decades and may have transmitted sensitive information to the police regarding 400 of his clients.

The revelations cast doubt on the legality of dozens of convictions – many of them high-profile – that could trigger an avalanche of appeals through the courts.

Mr. Quigley said he was not personally aware of a lawyer used in such circumstances in WA, both before and after his appointment as attorney general. But, as a precaution, he wrote to Mrs. Roberts "asking to get reassurance from the police commissioner WA that there was no similar use of a police informant in WA who violated the professional obligations as a coroner" .

The former police commissioner of WA, Karl O & # 39; Callaghan, said he had never heard of the practice before or after his appointment in the main role, but added that senior officials would not necessarily receive that type of information on any ongoing investigations.

A spokesman for Commissioner Chris Dawson said that while the Washington police "receive crime information in our community from any member of the public, they do not accept information from whistleblowers violating legal professional privileges".
