A person shall not be removed from employment or a position as a police officer of the New Jersey Transit Police Department pursuant to section 2 of P.L. 1989, c.291 (C.27:25-15.1), or suspended, fined or reduced in rank for a violation of the internal rules and regulations established for the conduct of employees of the New Jersey Transit Police Department, unless a complaint charging a violation of those rules and regulations is filed no later than the 45th day after the date on which the person filing the complaint obtained sufficient information to file the matter upon which the complaint is based. A failure to comply with this section shall require a dismissal of the complaint. The 45-day time limit shall not apply if an investigation of a police officer for a violation of the internal rules and regulations of the New Jersey Transit Police Department is included directly or indirectly within a concurrent investigation of that officer for a violation of the criminal laws of this State; the 45-day limit shall begin on the day after the disposition of the criminal investigation. The 45-day requirement in this section for the filing of a complaint against a police officer of the New Jersey Transit Police Department shall not apply to a filing of a complaint by a private individual.
