Final answer:
Yes, Sam must comply with Lisa's request for arbitration according to the Code of Ethics.
Step-by-step explanation:
Yes, Sam must comply with Lisa's request for arbitration.
As a REALTOR, Sam is bound by the Code of Ethics and Standards of Practice established by the National Association of REALTORS (NAR). The Code requires that REALTORS® submit to arbitration when requested by another party in a dispute arising out of a real estate transaction. By filing an ethics complaint and requesting arbitration, Lisa has initiated a dispute that falls within the scope of the Code, and Sam is obligated to comply.
An example of this can be seen in the NAR Code of Ethics, Article 17, which states that a REALTOR® shall not refuse to submit to arbitration in an ethics matter when required by an agreement to arbitrate.
