Military Justice Enquiries

DMDL is involved in actioning the outcomes of inquiries into military justice: more especially the discipline law aspects. These have included the 2005 Senate Foreign Affairs, Defence and Trade Committee's Inquiry into the effectiveness of Australia's military justice system and the FINAL REPORT OF THE INDEPENDENT REVIEW ON THE HEALTH OF THE REFORMED MILITARY JUSTICE SYSTEM (STREET & FISHER REPORT).

Legislative, regulatory and policy changes are being developed or considered in order to address agreed recommendations.

DMDL is also reviewing Part VI of the DFDA in order to provide command with some recommended changes to modernise our investigative capabilities within the ADF and more properly reflect the role and responsibilities of the ADF Investigative Service.
