Subject to the conditions set forth in §
10-5, the employee shall be entitled to be represented by the Attorney for the village; provided, however, that the employee shall be entitled to representation by private counsel of his choice in any civil judicial proceeding whenever the Attorney for the village determines, based upon his investigation and review of the facts and circumstances of the case, that representation by the Attorney for the village 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 Attorney for the village shall notify the employee in writing of such determination that the employee is entitled to be represented by private counsel of his choice. The Attorney for the village may require, as a condition to payment of the 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 representation by private counsel under the provisions of this section, the Attorney for the village 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 that the employee is entitled to representation under the terms of this section by the head of the department, commission, division, office or agency in which such employee is employed and upon an audit and warrant of the Mayor. 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 a special proceeding.
