(a) No member of the legislative body of a county who is also an employee of the same county or whose spouse is an employee of the same county may vote on matters in which such member has a conflict of interest. A conflict of interest is created under this section when a member is voting on a matter which, if approved by the legislative body, would increase the pay or benefits of that member or that member's spouse. The vote of any member having a conflict of interest shall be void if challenged in a timely manner. As used in this subsection (a), “timely manner” means during the same meeting at which the vote was cast and prior to the transaction of any further business by the body.

(b) Subsection (a) shall not prohibit a member of a local governing body of a county from voting on the budget, appropriation resolution, or tax rate resolution, or amendments thereto, unless the vote is on a specific amendment to the budget or a specific appropriation or resolution in which the member has a conflict of interest.

(c) Any member of a local governing body of a county who abstains from voting for cause on any issue coming to a vote before the body shall not be counted for the purpose of determining a majority vote. This subsection (c) shall not apply to any county having a metropolitan form of government and having a population in excess of five hundred thousand (500,000), according to the 1990 federal census or any subsequent federal census.

(d) Nothing in this section alters, amends, or otherwise affects § 12-4-101(a). In the event of any conflict between this section and § 12-4-101(a), § 12-4-101(a) shall prevail.

(e) The legislative body of any metropolitan form of government or charter form of government may opt out of this section by resolution.
