Cases are called when all the paperwork and interviews are completed. A defendant is processed and interviewed by the Pretrial Services Agency (PSA), and defense counsel, and the court case is prepared once the USAO/OAG has determined whether or not to prosecute. United States Marshals are responsible for transporting arrestees within the Courthouse. If a defendant has multiple cases in different courtrooms, this can significantly affect the time for the defendant’s appearance in C-10.
