(To clear my thought process ) Dharma is that which bears, that which provides stability to a thing, a person, or a nation in motion. Nyaya is specific to the individual; A person who abides in Dharma may still be affected by the Adharma of another who fails to uphold it then the State/Society must inject Nyaya to tha specific person or group or even state. Jurisprudence (in my limited understanding and information ) could not ditinguish between these two concepts and confused it with morale, divine rule, command, society, economics etc. These two are related, but Dharma is what guides the Naya but here it has nothing to do with legal system, it is independent and move with truth, whereas Naya alone requires legal system. Hence, Jurisprudence has long divorced its essence of Dharma (somehow natural school using reason could hover around truth) and focus on legal system alone. ..................
