Federal trial courts are primarily called:

Federal trial courts are primarily referred to as district courts. These courts serve as the general trial courts of the federal judicial system, where most federal cases are initially filed and heard. Each federal district court has jurisdiction over a specific geographic area, and they handle a wide range of cases, including civil and criminal matters.

Understanding that district courts are the first level of the federal judiciary is crucial. They are responsible for the trial phase of litigation, including the introduction of evidence, jury selection, and verdicts in both civil and criminal cases.

The other types of courts listed serve different roles within the judicial system. Courts of Appeal, for example, hear cases that have been appealed from district courts and do not conduct trials. Chancery courts are typically associated with equity matters and are primarily found in certain states rather than at the federal level. Superior courts are commonly used terms for state trial courts and can also vary by state jurisdiction. This distinction between court types helps clarify the specific function and authority of district courts within the federal judicial framework.
