Prominent Queensland barrister Tony Morris says his legal challenge to a speeding ticket isn't about money, but about taking a stand against unfair speed camera laws.

The Queen's Counsel, who headed a state inquiry into former surgeon Jayant Patel, challenged the $146 ticket in Queensland's Court of Appeal on Wednesday on the basis that he was not the driver of the car involved.

The Volvo is registered to him but Mr Morris won't reveal who was driving when the car was snapped travelling 7km/h over the 50km/h speed limit in Brisbane last year.

Outside court, he said the appeal wasn't about the fine, which he proposed to pay anyway, but about car owners being liable for offences they didn't commit.
