1. New Jersey Administrative Code, Title 11, Chapter 5 (New Jersey Real Estate Commission), Section 11:5-7.1(e): This regulation explicitly requires that every listing agreement for the sale of one- to four-family dwelling units must contain the following statement in large print: "As a seller you have the right to individually reach an agreement on any fee, commission, or other valuable consideration with any broker. No fee, commission, or other consideration has been fixed, controlled, recommended, suggested or maintained by any board of realtors or by any other person or entity." This directly supports the mandate for negotiation.
2. New Jersey Real Estate Commission, Real Estate License Law and Rules (N.J.S.A. 45:15-1 et seq. and N.J.A.C. 11:5-1.1 et seq.): The entire framework of the license law is built upon principles of fair dealing and preventing anti-competitive practices. N.J.S.A. 45:15-17(l) gives the Commission the power to suspend or revoke a license for "any conduct which demonstrates unworthiness, incompetency, bad faith or dishonesty," which would include price-fixing.
3. U.S. Department of Justice, Sherman Antitrust Act: Section 1 of the Sherman Act prohibits any contract, combination, or conspiracy in restraint of trade. Agreements among competing brokers to fix commission rates are a per se violation of this act. The requirement for individual negotiation stems directly from this federal law, which is a foundational topic in all state-sanctioned real estate licensing education.
