With the Cairn tax dispute, now over, what are the big learnings for India?

With the government paying Rs.7,900 as refund, the Cairn tax dispute is finally over. India must take home some key lessons.

Lastly, in any debate between form and substance, in the global legal arena, it is form that will have the upper hand in arbitration, not substance.
