The district shall provide to a commissioner or an employee such legal representation at the district’s expense as may be reasonably necessary to defend any claim filed against the commissioner or employee arising out of the performance, purported performance or failure of performance in good faith of duties for or employment with the district. This legal representation shall be a condition of service to or employment with the district and shall be provided by the district’s attorney or an attorney retained by the board of commissioners, except as may be provided under an insurance policy or self-insurance or joint insurance program.
