N.Y. CVS. LAW § 75-a : NY Code - Section 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.
