The National Institute of Military Justice is dedicated to advancing the fair administration of military justice and fostering improved public understanding of our military justice system.
Most of our advisors have served as Judge Advocates in the US Army, Navy, Marine Corps, Air Force and Coast Guard. Having served as prosecutors and defense attorneys in courts-martial and military commissions, as counsel in federal litigation, and as scholars in academia, our experts-on-call are available to provide in-depth commentary as SME sources for the media, governmental organizations, and non-governmental organizations on issues relating to military justice, international humanitarian law, and military commissions.
One of NIMJ’s strengths is the diversity of views among its Advisors. Because of this, the views expressed by these experts are offered in their personal capacities, and do not represent the views of the National Institute of Military Justice. When using our advisors’ expertise, we ask that media representatives please ensure that this distinction is clear.
Our NIMJ advisors acting as experts-on-call have volunteered to provide their expertise to the media on military justice, including courts-martial, the law of war, and military commissions. NIMJ does not provide endorsements of, or referrals or recommendations to any law firm, judge, or attorney, nor will its advisors provide individual legal advice arising from contact through this site.
Although some of our experts also operate as private attorneys, use of their law firm email or links does not constitute an endorsement or referral by NIMJ to these individuals. They have agreed to act as experts on call for the media in their capacities as NIMJ Advisors.
