I have to select any one of these legal rule or principle for instance: particularization, causation, redressability, attorney-client privilege, Fifth Amendment rule against self-incrimination, Canadian rule against self-incrimination,any of the civil discovery rules, summary judgment, hearsay, or any other rule or principle - and describe how I would change this legal rule or principle, and why I believe my change would improve the rule or principle. Could you help me out with one?
