Leaked NSW Police report says Defence failed to cooperate with investigation into Jedi Council scandal Former soldier was cleared of involvement in scandal and wants an apology

Former soldier was cleared of involvement in scandal and wants an apology Defence says it did cooperate with police and owes no apology

The confidential document obtained by the ABC also said the office of former Army Chief David Morrison knew of the scandal 11 months before he went public with his now-famous speech condemning those involved.

In 2013, General Morrison made global headlines when he delivered an ultimatum to those involved in the scandal on YouTube, saying he would be "ruthless in ridding the Army of people who cannot live up to its values".

According to the 120-page police document "the findings that the Chief of Army was not briefed in August 2012 are simply not supported", although the current Australian of the Year has always maintained he only knew of the affair shortly before he made the allegations of vile online behaviour public.

The report from the NSW "Strike Force CIVET" also cited "serious concern about the integrity and methodology of the Inspector General Australian Defence Force Report".

'I tried to kill myself'

Former Lieutenant Colonel Karel Dubsky was the highest ranked officer among the 17 men implicated in the Jedi Council scandal.

Investigations found he never opened any of the offending emails sent by a military contractor, and was eventually cleared of involvement, but his command was never restored.

He said the episode had destroyed his life.

"I was admitted into a psychiatric ward ... and I tried to kill myself in there," he told 7.30.

"And I tried again when General Morrison was named Australian of the Year."

The former soldier says he now wants Defence to officially clear his name.

"An apology for the way I was treated — that apology would involve saying I wasn't a part of the Jedi Council," he said.

Defence believes no apology necessary

In a statement, Defence rejected any suggestion of wrongdoing.

"With respect to claims that ADFIS [Australian Defence Force Investigative Service] lied to police about the existence of crucial evidence, the-then Chief of the Defence Force, General David Hurley, previously sought advice from NSW Police Commissioner Andrew Scipione," the statement said.

"Commissioner Scipione advised that the NSW Police Force was satisfied that investigators 'have been provided with all the relevant materials by ADF regarding this matter taking into account that Security Provisions may require screening/vetting of the information as of March 2013'.

"Commissioner Scipione also stated that the NSW Police Force is 'satisfied that ADF has not failed to cooperate, taking into account that Security Provisions may require screening/vetting of information'."

Defence said it believes no apology was owed to Mr Dubsky.

"In accordance with the principles of natural justice, all individuals subject to administrative and disciplinary actions in relation to the so-called Jedi Council matter were afforded due process, including an opportunity to reply," the statement said.

"All action was concluded in mid-2014 and Defence therefore considers this matter closed. Should the affected individuals elect to redress these administrative or disciplinary outcomes, other avenues include the Commonwealth Ombudsman or civil action."
