Ashley Black joined Mallesons in 1989 and became a partner in 1995, specialising in commercial litigation with an emphasis on the Corporations Act and regulatory matters.

Stuart Westgarth, president of the Law Society of NSW, said the appointment of a solicitor to the Supreme Court bench is testament to the professionalism and dedication of solicitors in NSW.

"In addition to his legal practice, Mr Black is a prolific author having contributed to a number of legal publications, including a leading Australian text on securities and financial services law. I believe he will make an exceptional judge," he said.

Black has a Bachelor of Arts, a Bachelor of Laws and a Master of Laws from the University of Sydney and received first class honours for all three degrees.

He was admitted to practice as a solicitor in 1987 and the following year held a position as a Judge's Associate in the Federal Court of Australia.
