Subject to the conditions set forth in Subsection A of this section, the employee shall be entitled to be represented by the Village Attorney; provided, however, that the employee shall be entitled to representation by private counsel of his choice in any civil judicial proceeding, whenever the Village Attorney determines, based upon his investigation and review of the facts and circumstances of the case, that representation by the Village Attorney would be inappropriate, or whenever a court of competent jurisdiction, upon appropriate motion or by a special proceeding, determines that a conflict of interest exists and that the employee is entitled to be represented by private counsel of his choice. The Village Attorney may require, as a condition to payment of fees and expenses of such representation, that appropriate groups of such employees be represented by the same counsel. If the employee or group of employees is entitled to be represented by private counsel under the provisions of this section, the Village Attorney shall so certify to the Village Board. Reasonable attorney's fees and litigation expenses shall be paid by the village to such private counsel from time to time during the pendency of the civil action or proceeding, subject to certification by the head of the department, commission, division, office or agency in which such employee is employed that the employee is entitled to representation under the terms and conditions of this section and upon the audit of the Board of Trustees and warrant of the Village Treasurer. Any dispute with respect to representation of multiple employees by a single counsel or the amount of litigation expenses or the reasonableness of attorney's fees shall be resolved by the court upon motion or by way of special proceeding.
