A former SA Health researcher has won the right to continue to pursue tech-giant Google, extending her long-running legal battle over material published on the internet.
The Supreme Court has ruled Janice Duffy can continue a new action against Google over defamatory material which continued to show up on internet searches.
Dr Duffy successfully sued Google for defamation in 2015 after its search algorithm connected her name to harmful accusations made against her by the members of a website.
She won damages of more than $100,000.
Google immediately launched an appeal, which was dismissed in 2017 by the Full Court of the Supreme Court.
On Friday, Justice Malcolm Blue ruled Dr Duffy could continue with her second action for defamation against the company, allowing her to amend her statement of claim.
He also rejected an application by Google to have the action dismissed.
"Google has failed to establish that there is no reasonable basis for the action," Justice Blue said.
"I dismiss its application for summary judgment."
Dr Duffy, who has represented herself for much of the proceedings, told the court at an earlier hearing that the case had left her "very, very financially strapped".
"In fact, I ran out of money completely in April 2015, and had to go to Centrelink," she said.
"I had nothing left. Even my superannuation (was gone)."
