From the ever informative Law and other things:
On further reflection, I find that the question of suo motu power to recommend is inextricably tied with the question whether the CEC can exercise both the power to investigate and recommend, which is against the rule of natural justice. The Constitution enables him to recommend removal of an EC, but not to investigate his so-called misconduct. The CEC ought to have entrusted the task of investigation to his third colleague, or some other neutral person or persons. The mixing up of these two roles vitiates his recommendation.
Never paid attention to this aspect of natural justice!
