The 2015 amendments to the Federal Rules of Civil Procedure were intended to reduce the costs and burdens associated with pre-trial discovery, while protecting litigants’ rights to relevant information needed to effectively assert their claims and defenses. Rule 1’s language on cooperation, Rule 26’s articulation of proportionality factors, Rule 34’s requirements for specificity in responses – have these amendments made a difference? Have they had unintended consequences? Have they changed day-to-day practice in federal (or state) litigation? The moderator has selected recent representative cases in each of these three areas, to be presented by your fellow Working Group members, for dialogue on these questions.
