A more thorough explanation:

Definition: An arm of the court is an officer of the court who performs tasks or duties related to the court's functions.

For example, a court bailiff is an arm of the court. They are responsible for maintaining order in the courtroom, ensuring the safety of the judge, jury, and other court personnel, and carrying out the orders of the court.

Another example of an arm of the court is a court reporter. They are responsible for creating a written record of everything that is said during a court proceeding. This record is used by judges, lawyers, and other court personnel to make decisions and prepare for future proceedings.

These examples illustrate the definition of an arm of the court because they both involve individuals who are responsible for carrying out tasks that are essential to the functioning of the court. Without these individuals, the court would not be able to operate effectively.
