Military law literature in India was established in 1930 by General C.H. Harrington out of a perceived necessity in order to avoid potential injustice within and outside of the armed forces. Military law is a body of law which governs how a member of the armed forces may behave, and as with all forms of law it is subject to periodic changes. The field is based upon official Acts of the Indian government, plus a number of unofficial writings on theoretical applications of law and how it may be changed.
