Independent director

This is u/s 149(6) of the companies act. Every listed company is required to have at least one thirds of the total number of directors as independent directors. The procedure to select an independent director is: select a person with appropriate knowledge, experience and skills with due diligence. You also need to ensure that the person appointed shouldn't suffer from any disqualifications and should fulfill the conditions specified in section - 149(6). I hope this is all you wanted :)
