If a commission member is absent from two (2) consecutive meetings without prior notification, or if a member misses one-fourth (1/4) of the regular or committee meetings during a year, that member may be dismissed from the plan commission by the village president, with the approval of the board of trustees, upon recommendation of the plan commission. A commissioner may petition the chair for a leave of absence due to lengthy illness or hospitalization, and this type of leave, if approved, would be exempt from this section. (1978 Code § 2-1-13)
