Final answer:
Discovery in federal cases allows defendants to request the disclosure of various types of evidence that the prosecution plans to use against them.
Step-by-step explanation:
Discovery in federal cases is governed by sections of Rules covered in the Federal Rules of Criminal Procedure. Collectively, these Rules provide a defendant, upon motion, rights to discovery concerning various types of evidence. The defendant has the right to request the disclosure of evidence that the prosecution plans to use against them, including documents, recordings, and witness statements. This allows the defendant to prepare a defense and challenge the admissibility of any illegally obtained evidence.
