What are courts of original jurisdiction responsible for?

Courts of original jurisdiction are responsible for the first hearing of disputes. This means that they are the initial court where cases are filed, and where evidence is presented, and witnesses are heard. These courts evaluate the facts of the case, interpret the law, and render decisions based on the evidence provided. Their primary function is to establish the facts and apply the law accordingly to resolve disputes, whether they are civil or criminal in nature.

In contrast, the other options reflect functions that do not align with the role of courts of original jurisdiction. For example, hearing appeals from lower courts is the function of appellate courts, which review decisions made by lower courts to ensure that the law was applied correctly and that legal procedures were followed. Overseeing regulatory compliance and conducting administrative reviews typically pertain more to specialized administrative bodies or tribunals rather than traditional courts of original jurisdiction.
