Members of boards, commissions, authorities, and other governing agencies must be permitted to operate without concern for the possibility of litigation arising from the faithful discharge of their duties.(2) All members of boards, commissions, agencies, authorities, and other governing bodies of any governmental entity, created by public or private act, whether compensated or not, shall be immune from suit arising from the conduct of the affairs of such board, commission, agency, authority, or other governing body. Such immunity from suit shall be removed when such conduct amounts to willful, wanton, or gross negligence.(c) When immunity is removed by this chapter any claim for damages must be brought in strict compliance with the terms of this chapter.(d) Notwithstanding this chapter or any other law to the contrary, a governmental entity that places and properly maintains a clearly visible and adequate flood warning sign or barricade at a flooded road area shall be immune from suit for any injury resulting from a violation of § 55-10-205(c). The immunity from suit shall be removed when the governmental entity's conduct amounts to willful, wanton, or gross negligence.
