Death penalty litigation: investigation and the preparation of petitions and briefs. Case selection and student assignments depend on both pedagogical factors and litigation needs of clinic clients. Students read the trial and lower court record and research legal issues. Some students are involved in investigation, while others primarily assist in the preparation of briefs, petitions and other case documents. No student will be required to participate in investigation. All students are included in discussions regarding the necessary investigation, research, and strategy for the cases.
