Which of the following is NOT a role of the Texas Real Estate Commissioner?

The Texas Real Estate Commissioner has a defined set of responsibilities related to the regulation of real estate practices in Texas. The role does not include enforcing criminal laws, which is primarily the responsibility of law enforcement agencies and the judicial system.

The Texas Real Estate Commission (TREC) is a regulatory body tasked with overseeing matters such as licensing brokers, establishing policies for the agency's operations, and managing the staff that executes the commission’s directives. Each of these tasks aligns directly with the commission's purpose of regulating real estate practices and protecting consumers, while enforcing criminal laws falls outside the commission's jurisdiction.

Thus, stating that the enforcement of criminal laws is a role of the Texas Real Estate Commissioner is incorrect, confirming that this choice accurately reflects a responsibility that the commissioner does not hold.
