The office of a former Victorian senator was used by a Labor councillor linked to alleged Mafia boss Frank Madaferri to improperly sign up members to the party, ALP documents reveal.

Internal ALP documents obtained by the ABC show Michael Teti, a powerful Labor figure in Melbourne's northern suburbs, used the Coburg office of then senator Mehmet Tillem for a meeting of his Fawkner branch in November 2013.

In a letter to ALP state secretary Noah Carrol, Mr Teti informed the party of a change to the time and date of the November meeting of the Fawkner branch.

"We will be changing our next meeting details to 12pm the 30th of November 2013 which will be held in senator Mehmet Tillem's office," Mr Teti wrote.

"It is expected that more than 6 new members maybe [sic] joining our branch at this meeting."

Documents seen by the ABC show Mr Teti actually signed up 11 new members at the November 2013 meeting.

When contacted by the ABC, five of the people listed as new branch members on internal party documents denied attending the meeting in Mr Tillem's office.

Two of those contacted were unable to explain how they came to be members of the party and said they had never signed an ALP membership application.

The grandson of one of the people who supposedly joined the party at the meeting said his grandmother, who has since died, was surprised when ALP letters began arriving at her home.

He said his grandmother, who was in her 80s and suffered from dementia, had never attended any ALP meetings and was not interested in politics.

Under ALP rules, a person applying for membership of a branch of the party must be present at the branch meeting or have attended a meeting in the previous six months.

The assistant state secretary of Victorian Labor, Kosmos Samaras, urged anyone with concerns about the operations of the Fawkner branch to report them to the party.

"All potential applicants are required to attend a local branch meeting and submit their application to join Labor in accordance with our rules," Mr Samaras said.

"Naturally, wherever such rules are not complied with, the Victorian Branch does take action to ensure our rules are upheld and followed.

"Where we have found a breach in our rules, applications are rejected," he said.

ALP moving to expel Teti over alleged Mafia links

Labor sources believe the 2013 meeting was used by Mr Teti to stack the Fawkner branch and consolidate his power base within the federal electorate of Wills.

A member found guilty of branch stacking can be expelled from the party.

The ALP is already moving to expel Mr Teti after it was alleged he supplied a gun to a Mafia figure who then used the weapon to threaten a woman.

In December last year Mr Teti was found guilty of carrying a loaded gun in a public place and placed on a good behaviour bond.

The 2013 meeting of Mr Teti's Fawkner branch took place at the same time and location as a meeting of the Moreland branch of the ALP, controlled by Mr Tillem.

At the time of the meeting, Mr Tillem was filling the temporary Senate vacancy after David Feeney's move from the Senate to the Lower House seat of Batman.

Mr Tillem lost his senate seat at the last election and now works as an advisor to Victoria's Minister for Tourism and Major Events, John Eren.

Mr Tillem has not returned calls but the ABC is not suggesting he knew of Mr Teti's links to the Madafferi family or of his branch-stacking activities.

Teti has no option but to resign: City councillor

Mr Teti has been a Moreland City councillor since November 2008 but has come under scrutiny for his poor attendance record.

Since October last year, he has attended six of the 12 council meetings. Council minutes show he has been late to the six meetings he has attended in that time period.

On June 10, Mr Teti was 37 minutes late to the council meeting, having missed the previous three meetings.

Under Victoria's Local Government Act, a councillor can be expelled for missing four meetings in a row without obtaining leave.

If Mr Teti is expelled from the ALP he will be able to remain as an independent councillor.

Fellow Moreland City councillor John Kavanagh said Mr Teti's poor attendance record and criminal conviction meant Mr Teti had no other option than to resign.

"I think he's crossed the line," Mr Kavanagh said.

"For a long time now he hasn't represented the residents and rate payers of Moreland effectively. He is no longer worthy of the position of councillor."

Federal MP supports moves to expel Teti from party

The federal member for Wills, Kelvin Thompson, who employed Mr Teti for a short time in 2009 said he was supportive of moves to expel him from the party.

Mr Teti resigned from his job as a junior electoral officer after just 29 days in Mr Thompson's office.

"He had not been a conscientious employee and we were not sorry that he decided to terminate his employment contract," a spokesman for Mr Thompson said.

"In light of [the Four Corner's] report about Michael Teti's conduct in 2013, Kelvin supports the efforts by the Victorian state secretary to seek Michael Teti's expulsion from the Labor Party."

Mr Teti could not be reached for comment.
