The Honourable Morris J. Fish - Third Independent Review of the National Defence Act

Acted as counsel to the Honourable Morris J. Fish, former Justice of the Supreme Court of Canada and Jurist in Residence at Davies, in the preparation and drafting of his report to the Minister of National Defence on specified provisions of the National Defence Act and their operation. The 400-page report delivered on June 1, 2021 includes 107 wide-ranging recommendations, a majority of which address the military justice system, including the independence of its actors, the handling of sexual misconduct allegations, military policing and police oversight. The remainder of the recommendations relate to military grievances and to the independent review process. Upon tabling of the report in Parliament, the Department of National Defence described the review as "the most comprehensive independent review and far-reaching examination of the military justice system since the reviews led by the former Chief Justice of Canada, Brian Dickson, in the late 1990s".
