Ms Gobbo on Wednesday told the Royal Commision into the Management of Police Informants that Mokbel "wanted to find out as much as he could about what they (police) did and didn't know", and Mr Dale "wanted to know if Tony wanted to kill him because he burgled a place that belonged to Tony."

Charges against former drug squad detective and Wangaratta businessman Mr Dale over the drugs house burglary at Oakleigh in 2003 were later dropped.

Ms Gobbo said she could not remember if Mr Dale was suspended at the time he contacted her in 2003, "but he was concerned about being charged in a conspiracy."

Counsel assisting the commissioner Chris Winneke asked Ms Gobbo if she accepted that it was "completely wrong" for her to have met with Mr Dale, suggesting it was "beyond the pale".

"I thought I'd be able to get information out of him that would assist people for whom I was acting and I concede that was the wrong motivation," Ms Gobbo said.

She earlier told the inquiry she knew she'd done the wrong thing in representing people including Mr Dale and Terence Hodson charged over the 2003 burglary.

She helped Hodson to inform on Mr Dale, provided legal advice to Mr Dale and then passed notes he gave her - to pass onto to solictors - to police. Burglary charges against Mr Dale were dropped after the murders of Terrence and Christine Hodson in 2003.

In 2009 Mr Dale was charged with murder of Terrence Hodson but those charges were also dropped after the murder of crown witness and notorious criminal Carl Williams.

Ms Gobbo gave legal advice to Mr Dale when he was charged with organising Hodson's execution.

She spent the night with Mr Dale after one of their meetings, telling the Royal Commission: "I was blind drunk to the point of literally blacking out, for the second time in my entire life."
