1. (a)Motion. A party may obtain discovery only upon motion, and for good cause shown.
2. (b)Forms. The forms of discovery which a Judge can order under paragraph (a) of this section include requests for admissions, requests for production of documents, interrogatories, and depositions.
3. (c)Limitations. Discovery may be limited in accordance with the terms of a protective order (see § 134.205). Further, privileged information and irrelevant issues or facts will not be subject to discovery.
4. (d)Disputes. If a dispute should arise between the parties over a particular discovery request, the party seeking discovery may file and serve a motion to compel discovery.
