Military law is the term used to designate the body of case law, statutes, and regulations governing military personnel. Three of our four lawyers are experienced, certified judge advocates (military lawyers) authorized to practice in all military jurisdictions worldwide. All served as prosecutors while on active duty and are thoroughly familiar with the military justice and administrative systems. Our firm handles military cases at the trial level, on appeal, and in administrative matters.
We represent clients at all phases of the military justice system. We have experience representing clients at general courts-martial (felony courts), special courts-martial (misdemeanor courts), and summary courts-martial (a unique military court), as well as pretrial investigations under Article 32, Uniform Code of Military Justice (UCMJ).
Servicemembers being tried by court-martial are entitled to an assigned military counsel provided without charge by the service (called “detailed counsel”). However, they also are entitled to hire civilian counsel at their own expense. Our lawyers are experienced in representing servicemembers from the very beginning of their cases. We conduct a thorough investigation of the facts and the applicable law, which helps us negotiate with the command to prevent charges, or get charges dismissed or reduced. If the case proceeds to trial, we are prepared to take on the Government at every turn. We represent enlisted and officer members of all services at courts-martial around the globe.
If there is a conviction and the convening authority approves a sentence that includes a punitive discharge (bad conduct discharge or dishonorable discharge) or one year or more of confinement, servicemembers get an appeal as a matter of right. Their case files are sent to the appropriate service court of criminal appeals: the Air Force Court of Criminal Appeals (AFCCA), Army Court of Criminal Appeals (ACCA), Coast Guard Court of Criminal Appeals (CGCCA), or Navy-Marine Corps Court of Criminal Appeals (NMCCA). After the service court decides the case, the losing party may petition the highest military court, the Court of Appeals for the Armed Forces (CAAF) (formerly the Court of Military Appeals, or COMA) for a discretionary review.
Again, servicemembers are assigned without charge a military appellate defense counsel, but are free to hire civilian counsel if they so choose. Our lawyers have extensive experience researching and preparing the written briefs submitted to the Courts, as well as orally arguing the case in Washington, D.C.
We are experienced in representing servicemembers in administrative matters as well, including administrative and medical separation processing, promotion and non-selection for promotion issues, officer misconduct, discharge upgrades, security clearance matters, and fitness report/performance evaluation appeals. We also submit application packages for the correction of military records to the various service boards such as the Air Force Board for Correction of Military Records (AFBCMR), Army Board for Correction of Military Records (ABCMR), Board for Correction of Naval Records (BCNR), and each service’s Discharge Review Board (DRB). We do not, however, handle matters pertaining to the Department of Veterans Affairs (VA).
