Agree with you that the case was complicated and also have thousands of pages to read and understand the case.
Lets be practical and ask yourself how much time you need to resolve a query between a group of persons who claim to be innocent if you were to be a JUDGE?
We are just following the same old tendency of our ancestors who learn the judiciary from British people.
We need a revolution here to break this system and have a new JUDICIARY SYSTEM where you dont have to wait for the judgement for years.
