Hundreds of NSW drivers taking mobile phone camera fines to court

Hundreds of New South Wales drivers stung by mobile phone detection cameras are fighting their infringements in court.

More than 30,000 motorists have been captured on the new cameras since they went live in March.

Nine News can reveal 463 drivers are challenging their fines and electing to fight the matter in court.

It comes as the State Government pushes for new legislation to make it harder for drivers to contest the fines.

The Government wants the onus of proof to be reversed, making it up to drivers themselves to prove the object they were photographed holding is not a mobile phone.

Criminal lawyer Michael Mantaj is vehemently opposed to the law change.

"It presumes that any object you hold is a mobile phone. It's almost as if by magic the law is turning a chocolate bar or a cup of coffee that you might be holding in your hand into a mobile phone," Mr Mantaj told 9News.

The legislation is currently sitting in the Upper House for review.

The State's Shadow Roads Minister John Graham says the Opposition would like to hear more debate on the new law.

"It would be a very significant step. We believe the courts are in a position to sort through these issues. If it becomes clear that's not the case, then parliament may have to act," he said.

The first court mentions against the new fines will be heard next month.
