Court bailiffs are law enforcement officers who are situated in courtrooms to maintain order and provide security. Along with guarding juries and enforcing rules of the courts, bailiffs open court by announcing the judges' arrival and close court by announcing the judges' departure. They may call witnesses to the stand and present the oath before witnesses take the stand. Court bailiffs might also provide administrative support to judges and jurors, stock courtroom supplies, deliver court documents and take custody of offenders.
As guardians of the peace, the main duty of civil bailiffs is to ensure the smooth functioning of the court system by preventing or correcting disruptive behavior. As sworn peace officers, they may carry firearms and have the authority to make arrests when warranted.
