So what you are proposing is PIOs get the right to vote while NRIs should be denied the same.
No.
PIOs with dual citizenship when they are in India for longer term can qualify for right to vote just like any citizen does.
NRIs when they are in India for longer term are no longer NRIs and will qualify for right to vote based on same rules.
When they both are outside India, none of them can vote as per current regulation for ANY citizen.
Its not that hard to understand, unless you are deliberately trying to not understand.. Dual citizenship does not necessarily confor additional rights to dual citizens. It only makes them equal to citizens and the same regulations apply for both of them. Neither a citizen not a dual citizen will be able to vote unless he fulfills the "ordinarily resident" requirement. He won't be able to register in voter list unless he proves that he is living in that electorate for long enough time.
And you also want PIOs to hold office in India with their citizenship status, which means the Chief Justice of India could very well be sitting in Washington DC or Riyadh.
If a person has a job in India, especially with a job like Chief Justice of India then he will have to stay in India. Unless you are suggesting that he can fly in daily from Washington DC or Riyadh. Workplace WILL be in India for such jobs, so you have to live in India. You are getting totally ridiculous now.
BTW, as an extension of what you are suggesting, EVEN now, a CJI can get PR in Canada or Australia and live indefinitely in those places. Does such a possiblity (remote) shifts Indian supreme courts to Australia or Canada or Malaysia?
Yeah, dude, let's allow that.
Well, "dude", like always, you don;t have a clue of what you are talking about. So chill.
