Explanation:

Katyayana describes the judicial process at length. The court of justice was attended by the king as the highest court of appeal. He was assisted by the judges, ministers, Chief Priest, brahmans, and assessors, varying in accordance with the needs of the individualcases.
On certain occasions representatives of commercial institutions were also invited to assist the king. Recognized judicial bodies were the guild, the folkassembly or council, a substitute appointed by the king in his own place (generally a brahman), and the kinghimself.
Judgement was based either on the legal texts or social usage or the edict of the king (which could not contradict the first two to any great extent).
Evidence was based on any or all of three sources, documents, witnesses, or the possession of incriminating objects.
Ordeal as a means of proof was not only permitted but used.
Katyayana accepted the theory of caste punishments, though it is doubtful if it was applied in every case
