Any commission member who shall, by his or her conduct, be subject to removal for cause, shall be entitled to a hearing before the city council and shall be entitled to representation at such hearing and shall be removed if three-fourths (3/4) of all of the members of the city council find that cause exists for removal of such member. Cause for removal shall include, but is not limited to, unwillingness on the part of the commission member to attend the regular commission meetings without proper excuse. Any commission member who shall miss two (2) consecutive meetings without excuse; that is, without some good reason or prior commitment causing the member to miss two (2) consecutive meetings, shall be subject to removal from the commission for cause. Any commission member having a proper reason for not being in attendance at a regular commission meeting shall get in touch with the chairman of the commission prior to the meeting, and the chairman shall excuse the commission member from attending the meeting if the excuse is valid and sufficient, and the commission member's absence from the meeting shall thereupon be considered as an excused absence.
