Any person, firm, or corporation not being duly authorized who shall contract for or bid upon the construction of any of the projects or works enumerated in G.S. 87-1, without having first complied with the provisions hereof, or who shall attempt to practice general contracting in the State, except as provided for in this Article, and any person, firm, or corporation presenting or attempting to file as his own the licensed certificate of another or who shall give false or forged evidence of any kind to the Board or to any member thereof in maintaining a certificate of license or who falsely shall impersonate another or who shall use an expired or revoked certificate of license, or who falsely claims or suggests in connection with any business activities regulated by the Board that a person, firm, or corporation is licensed under this Chapter, and any architect or engineer who recommends to any project owner the award of a contract to anyone not properly licensed under this Article, shall be deemed guilty of a Class 2 misdemeanor. And the Board may, in its discretion, use its funds to defray the expense, legal or otherwise, in the prosecution of any violations of this Article. No architect or engineer shall be guilty of a violation of this section if his recommendation to award a contract is made in reliance upon current written information received by him from the appropriate Contractor Licensing Board of this State which information erroneously indicates that the contractor being recommended for contract award is properly licensed.
