A mother and daughter who were injured when Salim Mehajer lost control of his $300,000 Ferrari are suing the Auburn deputy mayor for damages.

Nhu Hua, then 68, and Tuyet La, 40, were rushed to hospital in January 2012 when the then 26-year-old lost control of his Ferrari 612 Scaglietti, striking the pair on the footpath on The Boulevard at Lidcombe.

The pair suffered serious leg and pelvis injuries that required surgery at Westmead Hospital.

Ms Hua and Ms La launched civil proceedings against Mr Mehajer in the NSW District Court last year, and the hearing is set for November 9. The case is being handled by his insurer at the time, NRMA.

In October 2012, a month after he was elected deputy mayor of Auburn, Mr Mehajer was convicted of negligent driving in the Local Court and sentenced to 150 hours' community service and banned from driving for a year. But the conviction was overturned on appeal to the District Court.

Mr Mehajer told Fairfax Media: "The current proceedings are civil proceedings between the injured persons and the relevant insurer and, as they are ongoing, it would be inappropriate for me to comment further".

The millionaire property developer was not speeding at the time of the crash and claimed he had lost control of the 600-horse power luxury car when another pedestrian walked out in front of him.

Mr Mehajer's lavish wedding party in August - with four helicopters, a fleet of stretch limousines and a squad of motorbikes -  sparked renewed interest in his business dealings. He was fined $220 for illegally blocking Frances Street, Lidcombe, during filming of the festivities.

He is now facing legal action by the NSW Office of Local Government over allegations he voted on council rezoning plans without making a full disclosure of his property interests.

Mr Mehajer has previously locked horns with the Department of Fair Trading, after it refused to renew his building contractor licence in June 2014 on the grounds he was "not a fit and proper person".

That decision was based on "perceived inaccuracies" in the answers Mr Mehajer provided on an application form by his company, SM Engineering & Construction (NSW) Pty Limited, to become a licensed builder, rather than on his character.

Fair Trading's decision was overturned by the NSW Civil and Administrative Tribunal, which found Mr Mehajer was "an individual of considerable standing in the community".

"He has established to my satisfaction that he is a fit and proper person," Senior Member Stephen Frost said in his decision in December last year.
