Is there any estopple that Apex Court cannot initiate an exercise to cleanse the economy of black money - which evil could not be for the reasons best known to the polititians has not been addressed as yet.
The Apex Court functions on merits and there is a system at place for do's and don't as you yourself have admitted that Courts are well within their jurisdiction to act as keepers of a society's conscience if society wants it the Courts have the mandate - which becomes norm of the society meaning thereby that with the implied permission of the society the court is very much within its right to do the cleansing and there is no issue of tress pass as sought to be misunderstood by you.
On the issue of Judicial overreach may serve a purpose in all this by bringing the pertinent questions to the fore you have admitted that still this implied tresspass will result in good for the society.
In short the hidden message in this (Copied stuff I do not know from where) is that once our elected representative are insensative to the conscience of the society and forget their RAJDHARMA then (even presuming but not admitting) the implied tress pass for public good (ye public hai ye sab jaanti hai) becomes norm of the society.
If Court can play an active role in cleaning polution in air, rivers, industries (however insignificant it may be but the exercise was done keeping in mind the general welfare of the masses) then there is no reason that the same could not be done in making a positive change qua the black money. We should stop this intellectual moaning and groaning and support this initiative.
