Attorney-General Mark Dreyfus has ordered the Commonwealth to drop the prosecution of lawyer Bernard Collaery, four years after he was charged with conspiring to release classified information about an alleged spying operation in East Timor.
Mr Collaery was charged in 2018 for allegedly helping his client, an ex-spy known only as Witness K, to reveal details of the classified ASIS mission.
The Canberra lawyer was facing the prospect of jail, with his trial date set for October 24 in the ACT Supreme Court.
But Mr Dreyfus confirmed on Thursday he had now determined the Commonwealth prosecution should end.
"In taking this decision, I have had careful regard to our national security, our national interest and the proper administration of justice."
'A good decision for the administration of justice in Australia': Collaery
Mr Collaery released a statement in response to the charges against him being dropped, thanking his legal team at Gilbert + Tobin lawyers and the community at large for their support.
"I am very pleased that the new Attorney-General has looked at this prosecution and all it has involved and taken steps to bring the case to an end. This is a good decision for the administration of justice in Australia," he said.
"I want to thank all of the people across Australia who have supported me and worked so hard to assist me throughout this case. I am in awe of the depth of support in our community for ethical values. I also want to thank those close to me who gave me inner strength.
"I am deeply grateful for the inspirational and arduous work of the partners and staff of Gilbert + Tobin lawyers, and my dedicated team of barristers, all on a pro bono basis. Their resolute professionalism and humanity has restored my faith in the rule of law.
Partner at Gilbert +Tobin, Kate Harrison, said she had considered it a privilege for the firm to act for Mr Collaery in the case.
"The case raised important issues about the degree of secrecy permitted by our courts under current legislation to allow cases involving national security matters to be dealt with behind completely closed doors, even where they involve important issues of public interest," she said.
"The approach threatens the capacity of a defendant to receive a fair trial."
'An important day for Australian democracy'
Human Rights Law Centre lawyer Kieran Pender, who has advocated over several years for the charges against Mr Collaery to be dropped, said the Attorney-General should be commended for the decision.
"This is an important day for Australian democracy. Bernard Collaery should never have been prosecuted. The Attorney-General has done the right thing and should be applauded for that," he said.
"There are many important stories that would never have been told were it not for the courageous actions of those who spoke up."
Following the decision, the Human Rights Law Centre is calling on the Attorney-General to similarly intervene in the ongoing prosecutions of David McBride, who blew the whistle on alleged war crimes by Australian soldiers in Afghanistan, and Richard Boyle, who spoke up about unethical practices at the Australian Taxation Office.
Mr Pender said whistleblowers like Mr Collaery, Mr McBride and Mr Boyle make Australia a better place, and their prosecutions should be dropped "as a matter of urgency."
"The Collaery, McBride and Boyle cases are vivid illustrations of the importance of robust whistleblower protections and the damage done to the public interest when whistleblowers are prosecuted rather than protected.
"Those robust protections do not exist in Australia today and it's beyond time that changed."
Former prosecutor Nicholas Cowdery said he had been hoping the charges against Mr Collaery would be dropped, and was "very pleased" Mr Dreyfus had chosen to do so as one of his early decisions in the role of Attorney-General.
"I could never see how the public interest was being served by the prosecution of Collaery and Witness K and that was one of the principal tests that the Commonwealth DPP had to apply," he said.
"But there is at least the risk of a perception of a political motive for bringing the prosecution – the activity in East Timor having been conducted under a former Coalition government — so that brought a rather unpleasant tinge to the whole case."
