Final answer:
The chief trial courts of state court systems are often called circuit courts or district courts, handling a wide range of cases including civil, criminal, and family matters.
Step-by-step explanation:
Within the state court systems, the chief trial courts are often referred to as circuit courts or district courts. These courts serve as the primary forums for the majority of cases including civil, criminal, family, and traffic violations. They are where most noncriminal cases are resolved, often without a jury, as well as where serious criminal trials with juries take place. For example, in Michigan, circuit courts hear civil cases involving significant sums, serious criminal matters, and family cases. Each state has its own structure and terminology, but the term circuit court often indicates the court's general trial jurisdiction.
