Indiana Code Title 35. Criminal Law and Procedure § 35-34-2-7

Sec. 7. (a) If a witness before the grand jury refuses to answer any question or produce any item, the prosecutor may inform the court, in writing, of the question asked or item sought and the reason given for the refusal.  The court shall, after a hearing, decide whether the witness is required to answer the question or produce the item and the witness shall be informed immediately of the court's decision.

(b) If the court determines that the witness must answer the question or produce the item and the witness continues to refuse, he shall be brought before the court and the court shall proceed as if the witness had refused in open court.

(c) If the court determines that the witness may properly refuse to answer a question or produce an item based upon his privilege against self-incrimination, the prosecutor may request the court to grant use immunity to the witness under section 8 of this chapter.
