Look through the history of Supreme Court judgements and you will get the answer. Do you want references?
Article 370 cannot have been abrogated legally. Declaring its abrogation null and void takes just that amount of time for the justices to forget that they can be blackmailed by sexual harrassment charges that mysteriously vanish into thin air once they start behaving themselves, or that they can be rewarded with a wholly undeserved Rajya Sabha seat at the end of their compliant tenure.
Is that feeling was same when a son of former Chief minister (Belongs to congress party) made Chief Justice of India.
Hint - That was a same fellow you are discussing in your post.
