Judge Advocate General's Corps, also known as JAG or JAG Corps, refers to the legal branch or specialty of a military concerned with military justice and military law. Officers serving in a JAG Corps are typically called Judge Advocates. Only the chief attorney within each branch is referred to as the "Judge Advocate General"; however, individual JAG Corps officers are colloquially known as JAGs.
Judge Advocates serve primarily as legal advisors to the command to which they are assigned. In this function, they can also serve as the personal legal advisor to their commander. Their advice may cover a wide range of issues dealing with administrative law, government contracting, civilian and military personnel law, law of war and international relations, environmental law, etc. They also serve as prosecutors for the military when conducting courts-martial. In the United States military, they are charged with both the defense and prosecution of military law as provided in the Uniform Code of Military Justice. Highly experienced officers of the JAG Corps often serve as military judges in courts-martial and courts of inquiry.
The Judge Advocate General's Corps of the United States Army is the legal arm of the United States Army. The Corps is composed of Army officers who are also lawyers and who provide legal services to the Army at all levels of command, and also includes legal administrator warrant officers, paralegal noncommissioned officers and junior enlisted personnel, and civilian employees. The Judge Advocate General is a lieutenant general. All military officers are appointed by the U.S. President subject to the advice and consent of the Senate, but the Judge Advocate General is one of the few positions in the Army explicitly provided for by law in Title 10 of the United States Code, and which requires a distinct appointment. Officers who have already been appointed to another branch of the Army are administratively dismissed and simultaneously recommissioned anew as judge advocates, rather than merely transferring branches.
The Judge Advocate General's Corps also known as the "JAG Corps" or "JAG" is the legal arm of the United States Navy. Today, the corps consists of a worldwide organization of more than 730 Judge Advocates, 30 limited duty officers (law), 500 enlisted members and nearly 275 civilian personnel, serving under the direction of the Judge Advocate General of the Navy.
The headquarters of the Judge Advocate General's Corps of the United States Department of the Navy is located at the Washington Navy Yard in Washington, D.C.
In 1775, the Continental Congress enacted the Articles of Conduct, governing the ships and men of the Continental Navy. However, soon thereafter, all of these ships were sold and the United States Navy and Marine Corps were disbanded. In July 1797, Congress, after authorizing construction of six ships, enacted the Rules for Regulation of the Navy as a temporary measure. Then, in 1800, Congress enacted a more sophisticated code adopted directly from the British Naval Code of 1749. There was little or no need for lawyers to interpret these simple codes, nor was there a need for lawyers in the uncomplicated administration of the Navy prior to the American Civil War.
In the United Kingdom, the Judge Advocate General and Judge Martial of all the Forces is a judge responsible for the court martial process within the Royal Navy, British Army and Royal Air Force.
The post is regulated by the Courts-Martial (Appeals) Act 1951. The appointment is made by the British Sovereign on the recommendation of the Lord Chancellor. Formerly, the Judge Advocate General had to be a barrister, advocate, or solicitor with higher rights of audience, of 10 years' standing. As of 21 July 2008 the experience needed to qualify was reduced in line with a general move to broaden diversity in the judiciary. An appointee who has practised in England and Wales now has to satisfy the judicial-appointment eligibility condition on a 7-year basis, while a practitioner from Scotland or Northern Ireland will need 7-years' standing as barrister, advocate or solicitor. The post is always held by a civilian rather than a commissioned officer, however an appointee may have previously been a member of the armed forces. In practice the post is held by a Senior Circuit Judge.
A Judge Advocate General is a principal judicial officer for an armed service. Relevant articles include:
The Judge Advocate General (JAG) is the Chief of the combined Legal and Judicial system of the three Armed Forces in Sri Lanka. Holds full authority over all legal and Judicial matters concerning the Army, Navy and the Air Force of Sri Lanka. The authority to appoint the "Judge Advocate General" (JAG) is exclusively vested with the Head of State, H.E. the President of the Democratic Socialist Republic of Sri Lanka.
In the absence of the JAG, the Judge Advocate (JA) in the Sri Lankan Armed Forces is the legal and judicial chief of the respective service appointed by the Commander of that armed force. The Sri Lanka Army, Sri Lanka Navy and the Sri Lanka Air Force has its own legal branch with legally qualified officers. Each service may have its own Judge Advocate, held by an office of the rank of Major General, Brigadier, Rear Admiral, Commodore or Air Commodore. Judge Advocate General of a certain service may preside over and court martial on another service. JA officers provide legal help to the military in all aspects, in particular advising the presiding officers of courts-martial on military law. Appointment could be made to a serving legal officer or lawyer outside the service, normally a senior member of the Attorney-General's Department.
