N.J. Stat. § 34:20-6
If the Commissioner of Labor and Workforce Development determines, after investigation, that an employer or any officer, agent, superintendent, foreman, or employee of the employer has knowingly failed to properly classify an individual as an employee in accordance with section 4 of this act and failed to pay required wages, benefits, taxes or other contributions, or if a final conviction and disposition of a violation of this act is made pursuant to section 5 of this act in which the violator is found to be guilty of a crime of the second, third or fourth degree, then the commissioner shall place the employer on a list of employers who are prohibited from contracting, directly or indirectly, with any public body for the construction of any public building or other public work projects, or from performing any work on the same, for a period of three years. The commissioner shall give notice by mail of that list to any public body who shall request the commissioner so to do.
In the case of a determination by the commissioner, if the person responsible denies that a failure to properly classify an employee has occurred, he shall have the right to apply to the commissioner for a hearing in accordance with the "Administrative Procedure Act," P.L. 1968, c.410 (C.52:14B-1 et seq.), which shall be afforded and a decision shall be rendered within 48 hours of the request for a hearing. The commissioner may bring an action in Superior Court to enjoin or invalidate any contract award made in violation of this section.
