The revelation follows claims by South Eastern Metropolitan Region MP Inga Peulich in State Parliament on Thursday that Cr Stephen Dimopoulos had committed electoral fraud witnessed by councillors Geoff Lake and Paul Klisaris and former councillor Dane Manzie.

The allegation, made under Parliamentary privilege, has been strenuously denied.

Ms Peulich told MPs she was raising a number of matters in the light of concerns raised about Brimbank Council.

"The most serious case, I believe, is one that was reported and submitted to the [Victorian Electoral Commission] as well as to the Ombudsman, which alleges that indeed a fraudulent nomination form for a council candidate was signed by Labor councillor Stephen Dimopoulos in the presence of councillors Geoff Lake and Paul Klisaris as well as former councillor Dane Manzie and submitted by a staff member of Cr Klisaris'.

"These matters are yet to be addressed and responded to even though they have been submitted some time [ago]."

Cr Dimopoulos said Ms Peulich's allegations were "absolutely false" and he had never signed another candidate's nomination form.

Cr Klisaris said he had never seen Cr Dimopoulos sign another candidate's nomination form. "I know that this is something Stephen would never do".

When the Journal spoke to the candidate on Thursday, they did not remember the 2005 council elections because it was "so long ago", but said they believed they had not handed in the nomination form themselves. Later the candidate called back, saying they now clearly remembered signing the form and handing it in personally.

Documents that would help shed light on the incident were destroyed late last year, said the council's civic and governance co-ordinator, Nick Andrianis, in response to a Journal Freedom of Information application lodged on May 20 to view the 2005 council election nomination forms.
