(a) It is a ground for removal from the commission that a member:
(1) does not have at the time of taking office the qualifications required by Section 5.053(b);
(2) does not maintain during the service on the commission the qualifications required by Section 5.053(b);
(3) is ineligible for membership under Section 5.053(a), 5.059, or 5.060;
(4) cannot, because of illness or disability, discharge the member's duties for a substantial part of the member's term; or
(5) is absent from more than one-half of the regularly scheduled commission meetings that the member is eligible to attend during each calendar year without an excuse approved by a majority vote of the commission.
(b) The validity of an action of the commission is not affected by the fact that it is taken when a ground for removal of a member of the commission exists.
(c) If the executive director or a member has knowledge that a potential ground for removal exists, the executive director or member shall notify the presiding officer of the commission of the potential ground. The presiding officer shall then notify the governor and the attorney general that a potential ground for removal exists. If the potential ground for removal involves the presiding officer, the executive director or another member of the commission shall notify the member of the commission with the most seniority, who shall then notify the governor and the attorney general that a potential ground for removal exists.
