In my view, I'm most fascinated by constitutional law. How to work the constitution is far more important than how to write it. It is much easier to write the constitution. I recall when the Foreign Minister of Bangladesh came to visit me, (to draft the Bangladesh Constitution). I was the Additional Solicitor General then. We gave them ideas and drafts were exchanged, but it didn't last for more than a couple of years. Writing a constitution is simpler; borrowing ideas from everywhere is nothing great. How to work the constitution is a grave challenge and it's fascinating.
