The deputy mayor of Auburn in Sydney's west, Salim Mehajer, says he will not resign despite calls from four of his colleagues to do so.

Cr Mehajer has been making headlines ever since his lavish wedding closed streets in Auburn last month.

Four councillors are opposing him — Irene Simms, George Campbell, Semra Batik-Dundar and Tony Oldfield.

They have called an extraordinary meeting for tonight with six items listed on their notice of business.

"Number one is asking for Councillor Mehajer to resign," Ms Simms said.

"We can't make him leave, but we are asking him to leave and giving basically a vote of no confidence in the council."

Ms Simms and her three colleagues said Cr Mehajer had a conflict of interest as a developer on council.

They say he has been taking advantage of laws introduced by the State Government in 2012 which allow councillors to vote on amendments to development applications even when related to their own properties.

"Under those 2012 changes, a councillor was able to vote on a Local Environment Plan (LEP) even when they had a pecuniary interest," Ms Simms said.

"The LEP is what determines how high a building can be — so say a councillor was a developer who proposed a three-storey unit block, they could vote to make that 10 storeys.

"They couldn't vote on the actual development applications when they came before council, but they've been able to manoeuvre changes that are certainly favourable for them in the future."

The State Government has now repealed those laws, introducing changes into NSW Parliament yesterday.

"We said we would review Section 451 of the Act again to make sure councillors cannot vote on any matters where they have a pecuniary interest. We are acting on that promise," Local Government Minister Paul Toole said.

But the four councillors still want Cr Mehajer to resign.

Mr Campbell said he hoped some of the councillors who backed the deputy mayor so far would change their minds.

"One always lives in hope and I think there's a possibility that they will switch sides," he said.

Mehajer says developer job has nothing to do with council role

But the deputy mayor is standing firm.

"I will not be resigning and I will not allow anyone into forcing me to resign unjustly," Cr Mehajer said.

"It is evident that my performance is not in question. The call appears to be a hidden agenda to acquire my position."

He described tonight's extraordinary meeting as "just one of their many vile tactics" and said his job as a developer had nothing to do with his role on council.

"All the properties I have purchased in my local government area were purchased years before I was appointed a councillor for Auburn," he said.

Mr Toole is sending a representative to tonight's meeting but he said at the moment it was still a matter for the council to resolve.

"The councillors are elected for a four-year period and they'll have an opportunity next year in September to either return those councillors or vote for a new councillor to elect them," he said.

The council elections are a year away but Auburn council will vote on their mayor and deputy mayor by the end of this month.
