§ 75-a. Civil service proceeding; commencement upon alleged violation of certain provisions of the labor law relating to police officers. 1. Any police officer alleging a violation of section two hundred fifteen-a of the labor law may institute a proceeding pursuant to the provisions of his collective bargaining agreement. If no such agreement exists a complaint may be filed by a police officer with the state or a municipal civil service commission alleging a violation of section two hundred fifteen-a of the labor law; as a condition of entertaining such complaint the commission may require a police officer to exhaust all remedies available to such employee pursuant to the provisions of a collective bargaining agreement and the rules and regulations of the employer. Upon the filing of such complaint or upon its own initiative the commission having jurisdiction may investigate and upon finding an improper transfer or other penalty in violation of such section, enforce the provisions of such section. The commission may exercise any powers heretofore granted to it by provision of this chapter or by any other provision of law necessary for the enforcement of the provisions of section two hundred fifteen-a of the labor law.

2. Nothing in this section shall be construed to abrogate, impair, alter, or in any way modify any right of action in law that an employee, alleged to have been penalized, may have.
