Linking Vedas to Judiciary

 I know I am not the first one neither the last one to try this thing. Few problems one encounters while doing so:

a. Smritis who are considered to be source of procedural law like any other procedural law are plain rules without their direct link to Vedas (except Rishi giving credit to Vedas).

b. Even pioneers like Adi Guru Shankaracharya explained Upanishads only and discarded Karmakanda etc. and modern time Swami Vibekananda etc. too only explained Upanishads. 

c. Upanishads are fruit part of Vedas, at max fruit can provide seed for next cycle of the fruit tree.

d. Dayananda Saraswati and Sri Aurobindo went on length to explain Vedas but they are not connected to question of justice at all. Pattern of their explanation at max touched upon psychological phenomenon and mostly around physical phenomenon. it will be like trying to explain Law by using Physics. 

e. One beautiful example is economic procedures explained by Kautilya after giving saluation to Shree Hari (Shree=Laxmi and Hari=Vishnu). Reading text of Keynes only one would have been able to know why he wrote about State first and then went to describe procedure to do this and that. He was envisioning the whole economy unlike Classical Micro-economist whose sole focus were on production and distribution in one economic unit. 

Then how can we accomplish this task? sometime I feel we is not a fit word here.
