Investigative journalist Charlotte Grieve and media lawyer Dean Levitan discuss the first successful use of the new public interest defence to defamation. Charlotte and other Nine journalists were sued by high-profile orthopaedic surgeon Dr Munjed Al Muderis over stories about his patient care. A Federal Court judge concluded the stories were in the public interest and dismissed the case. The surgeon has appealed in a case that will further test a defence that could boost investigative journalism in Australia.
