The Independent Commission Against Corruption quizzed councillor Frank Gigliotti on his and other councillors' involvement with company Quattro Employment Services during public hearings in February.

The company's five directors were all members of the Labor Party and included: former deputy mayor Kiril Jonovski, former councillor Zeki Esen, former councillor Frank Gigliotti, and senior Labor Party figure and former council manager Joe Scimone.

At the time of his appointment to Quattro, Mr Scimone was also a director of development consultancy firm JS Consulting Services Pty Ltd.

The company aroused interest among ICAC officers partly because it shares its name with a controversial proposal by developer Frank Vellar.

Mr Vellar's proposal, named Quattro, was later found by ICAC to have been approved following corrupt behaviour by Mr Vellar and former senior council planner Beth Morgan.

When asked about the company's name in public hearings, Mr Gigliotti said there was no link to Mr Vellar.

"(It was named Quattro) because there were four of us, like were setting it up and Quattro means four."

He went on to say the company never operated commercially.

"The initial purpose was we were looking at skill labour, bringing skill labour into, into Australia," he said in testimony.

"We've never traded."

Almost a year after it was created, the company has now been deregistered by Mr Gigliotti with assets of less than $1000.

All the directors of the company have since been expelled from the Labor Party. Four of the five have appealed their expulsion, but the ALP has declined to identify who. Labor is also awaiting the third and final ICAC report before making a decision on the their fate.

The next ICAC report is due in coming months.
