There's the implicit rapping of knuckles. Showmanship or how far will it go?
The CBI is their baby, meant to be joined at the hip. However rebellion like this is unprecedented. The CJI is new but the institution is old. Preserving it's ways despite the not so gentle nudge from the Govt.
In effect what power do they have except of judgement, the facade that society putes up to hide it's gross negligence of morals. Will the Govt get away with it's interfering ways, will they reform from the struggle each of these independent institutions are putting up.
Maybe it is a sign of independence when you can defend your turf. The lack of it means your inevitable death in the brutal realpolitic of modern times.
