GOM (Group of Ministers) entrusted with the job of making out CBI a constitutional entity like EC, CAG or CVC, has had their own way. A panel of Judges will monitor the investigation part; prior permission is required to investigate Jt. Secretary level Babus and the permission will be given by the a Group of Secrataries drawn from the ministries, which means CBI is not empowered to suo moto to investigate anyone. Do you think that these Group of secretaries will give permission to prosecute their colleague? In nutshell, the political Bosses of these Secretaries will be calling the shots.
One cannot give absolute autonomy to CBI.. there has to be some check and balance. regarding the question of Babus giving permisison for other Babus' investigation.. we have Supreme Court to check on this, if CBI is really interest. We have PIL or Media as well.. What matter is INTEGRITY.. where ever one is placed.
