(a) In General

If a party who has been authorized to proceed in forma pauperis desires the attendance of any witness or the production of any documents or evidence by subpoena or writ, that party shall file a motion containing the name, address, and, if applicable, the inmate number, and a brief statement of the expected testimony of, or of the documents or other evidence to be produced from, each witness not later than twenty-one (21) days before the trial, hearing, or deposition where the witness is expected to testify or produce the requested evidence.  If a witness's stated testimony, or the requested evidence, is not material to the claims or defenses at issue in the case, is repetitive, or unduly burdensome, the court may, in its discretion, decline to order or otherwise limit, the production of the witness or of the requested evidence.
