THE girlfriend of senior Crown prosecutor Margaret Cunneen's son, under investigation for allegedly faking chest pains at a car crash site, has been slammed in court for her "poor" driving record. Sophia Alexandra Tilley pleaded guilty to running a red light on South Dowling St, Paddington on July 26 of this year. Sophia Tilley enters the Downing Centre court complex for a traffic matter. The Downing Centre Local Court was shown footage of the incident, where the 25-year-old can be seen braking as the car sails through the intersection. It was less than two months after a May 31 accident on Willoughby Road where Ms Tilley's car was struck from behind by a pizza delivery van. That incident is now under investigation by the Independent Commission against Corruption, amid allegations Ms Cunneen instructed Ms Tilley to say she had chest pains in order to avoid a breath test at the scene. Ms Tilley, an aspiring real estate agent, is in a de facto relationship with Ms Cunneen's eldest son Stephen Wyllie. The intersection on Willoughby Rd and Frenchs Rd Willoughby where Sophia Tilley smashed her car. Magistrate Lisa Stapleton rejected an application for the traffic case to be dismissed under a section 10, instead convicting her and fining her $615. The court heard Ms Tilley was caught speeding on the Hume Highway over the Easter long weekend of this year. Magistrate Stapleton said to Ms Tilley "you have a limited (driving) history and it's a poor one." Ms Tilley renewed her learner licence in 2013, and a short time later was caught driving unsupervised. The court heard that, despite still being on P plates, Ms Tilley had five driving offences on her record. A judgment on Ms Cunneen's attempt to stop a public ICAC inquiry from going ahead will be made in the Supreme Court at 2pm. Ms Tilley was accompanied by her parents for today's hearing.
