The question of criminal- legislators !

The relationship between politicians and crime is legendary, so is, the idea to ban criminals to enter politics. However the solution is not suitable in Indian context with our sluggish judiciary system. Supreme Court has been trying to put an end to this, but without success.

Economists like S.A. Aiyar and Bimal Jalan are arguing for a different approach. I.e to speed up the court cases of the legislators with criminal cases. Their argument is that, with a system like that, the criminals abstain from entering foray fearing that their case will come to an end soon the verdict might come against them. I liked this solution very much. But there is a small problem with it.

What if, the accused is proved guilty? We have to remove him/her from legislation. Then what? Elections have to be conducted in that constituency again. And what if the next candidate also proven guilty?

Extending that idea, why cant we make the time between nominations to elections six months or one year, and ask the courts to speed up the process of the cases on the contestants. This way, people don't have to vote multiple times and legislature will be criminal free.
