(a) It is a ground for removal from the advisory board that a member:
(1) does not have at the time of taking office the qualifications required by Section 401.015(a);
(2) does not maintain during service on the advisory board the qualifications required by Section 401.015(a);
(3) is ineligible for membership under Section 401.015(c), (d), or (e);
(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 half of the regularly scheduled advisory board meetings that the member is eligible to attend during a calendar year without an excuse approved by a majority vote of the advisory board.
(b) The validity of an action of the advisory board is not affected by the fact that it is taken when a ground for removal of an advisory board member exists.
(c) If the commissioner has knowledge that a potential ground for removal exists, the commissioner shall notify the advisory board chairman of the potential ground. The advisory board chairman shall then notify the governor and the attorney general that a potential ground for removal exists. If the potential ground for removal involves the advisory board chairman, the commissioner shall notify the next highest ranking officer of the advisory board, who shall then notify the governor and the attorney general that a potential ground for removal exists.
