An informed one can only expect such nonsense from an ex bureaucrat...I suspect if he has even cared to go through the full judgment. To quote him in article...
"If a contract is bad in law it can and should be set aside by the courts. But to the best of anybody's knowledge there has been no determination that the Concession Agreement, the basic contract between state authorities and NTBCL, is bad in law"

IMO AHC should have gone even further may be suo moto and book those bureaucrats who designed and approved such CA. In so called Indian democracy judiciary is the only pillar that's standing still as yet.
