The Nyaya Shastra of Goutama Rishi (anyone here familiar with it / read it?) is primarily a treatise on Logic - not justice. The word 'nyaya' in hindi means justice, but in Sanskrit (especially in the context of the text we are referring to) the word means a system/ methodology of logic. It became a corollary that by using such a system of logic, justice could be meted out.
But the point I am emphasizing here is that the original intention of Gautama while compiling the Nyaya Sutra was not with the idea of formulating a CIvil Procedure Code or an vedic version of Indian Penal Act.
Nyaya Sutra is a system of philosophy which tries to establish the presence of God, the relationship b/w aatma and God, and the aatma and the world, through a method of systematic logic by menas of garnering information. It ranks alongside Yoga and Vendanta one of the six systems of Philosophy.
Several commentators have written commentaries on the Nyaya Sutras. An excellent English translation by Sri. Sathish Chandra Vidyabhushan can be read here
