(a) has been adjudged an insolvent;
(b) has been convicted of an offence which, in the opinion of the Appropriate Government, involves moral turpitude;
(c) has become physically or mentally incapable of acting as a Member;

Legal Commentary & Landmark Judgments: Section 90
Section 90 of the Act prescribes the procedure for the removal of a Member of the Appropriate Commission, requiring an inquiry and adverse finding by the Supreme Court (for Central Commission) or High Court (for State Commission) on grounds of proven misbehavior or incapacity.
Any attempt by a State Government to curtail a commissioner's tenure or remove a member without a formal High Court inquiry under Section 90 is unconstitutional and can be stayed immediately under Article 226.
