Establishes criminal penalties for certain violations of the "New Jersey Prevailing Wage Act."

S 3187 makes it a fourth-degree crime for employers to knowingly falsify payroll records required under New Jersey's Prevailing Wage Act or to make false statements on public works contractor registration forms. Currently, such violations carry civil penalties like fines ($2,500-$25,000) and disqualification from public work, but this bill adds criminal penalties including up to 18 months in jail and fines up to $10,000 - applied in addition to existing penalties. The bill also requires county prosecutors or the Labor Commissioner to notify the Attorney General about violations, allowing the Attorney General to decide whether to prosecute directly or refer the case to local authorities. It directly affects employers working on public construction projects in New Jersey who must comply with prevailing wage requirements.
