Controversies preceding Justice Khehar's appointment
On December 23, Supreme Court with respect to a petition filed by lawyers' body opposing elevation of Justice Khehar, termed it as "virtually infructuous" as President had already issued a notification.
Again, on December 30, apex court dismissed a lawyers' petition which challenged Justice Khehar's appointment as next CJI.
Apex court said there was "no question" of him being considered ineligible for CJI's post.
Outgoing CJI Thakur cautions Justice Khehar
"The present has great challenges. We have three crore cases. We have problems of infrastructure. We have problems of judge strength being low. But please remember, we will have greater challenges in the future and that is what we have to be prepared for."
