—Discovery in Habeas Corpus

(a) Discovery, as of right, is limited to: (1) A list of witnesses; (2) A statement of the subject matter upon which any expert witness is expected to testify; (3) A statement of the opinions the expert is expected to render and the ground for each opinion. (b) The parties may cooperatively engage in informal discovery. The provisions of Chapter 13, Discovery and Depositions of the rules of practice, do not apply to habeas corpus proceedings. (c) Upon motion, the judicial authority may order such other limited discovery as the judicial author- ity determines will enhance the fair and summary disposal of the case.
