Answer: statutory law
Step-by-step explanation:
Statutory law is also referred to as statute law and it is defined as a written law that is passed by the legislature.
From the question, we are informed that a license holder was tried in a state district court on a complaint arising from a real estate transaction and that the court ruled that, among other transgressions, the defendant had violated the Texas Real Estate License Act. This shows that the judge decision was based upon statutory law.
