Former Auburn deputy mayor Salim Mehajer's defence team has abandoned his case in which he is accused of assaulting and robbing a taxi driver.

Mr Mehajer is accused of stealing driver Nazir Syed's phone, throwing it out of the taxi and hitting him with an Eftpos machine in an altercation outside The Star casino in Sydney in the early hours of April 2, 2017.

The 31-year-old property developer denies the allegations and has pleaded not guilty to assault occasioning actual bodily harm, larceny, destroying or damaging property and common assault.

On Wednesday, the matter was listed for a rescheduled hearing at Downing Centre Local Court, after Mr Mehajer was involved in a car crash on the way to the original trial in October 2017.
