What set up regional courts for the U.S with 16 judges and other officials?

To identify the setup of regional courts in the U.S. with 16 judges and other officials, we can refer to the United States Constitution and the federal court system. There are three levels of federal courts: district courts, appellate courts, and the Supreme Court. In this case, we will focus on the district courts.

The U.S. Constitution established the federal court system and authorized Congress to create and organize the federal judiciary. In 1789, the Judiciary Act was adopted, which created the first federal district courts. However, this act did not explicitly outline the number of judges or officials in each district.

That being said, the current structure of regional courts in the U.S. is based on the division of the country into 13 judicial circuits. Each circuit has a court of appeals assigned to it, consisting of multiple judges. These appellate courts hear appeals from the district courts within their jurisdiction. However, it is important to note that none of the circuits have exactly 16 judges.

To obtain a precise answer regarding regional courts with 16 judges and other officials, further research on specific legislation, such as the creation of special courts or amendments, may be required. Additionally, it's worth noting that the number of judges and officials within the regional courts may have changed over time due to various factors, including statutory changes, caseload, and judicial appointments made by the President and approved by the Senate.
