For all the people who bought Shares a long time ago, when there was no requirement for PAN card. Surely all these people have a legal right to sell the shares without a PAN card. On the Grounds that they were not told at the time of purchase that they will require a PAN card to sell the shares.
They can force the new buyers and new sellers to have a PAN card to make sure that all shares are regulated under the PAN system.
Surely SEBI have to make provision for old share holders and give them one chance to sell without pan card.
