This video describes amendments to Federal Rules of Civil Procedure 26(b)(1), 26(c)(1)(B), 26(d), and 34 that became effective on December 1. Amendments to Rule 26(b)(1) are designed to promote proportional discovery: discovery tailored by the judge and the parties to meet the reasonable needs of the case. Proportional discovery provides the information needed by the litigants to prove their cases, but avoids excess and waste. Judges are encouraged to engage in a dialogue with the parties regarding the amount of discovery reasonably needed to resolve the litigation. This video also describes amended Rule 26(c)(1)(B) on cost shifting, an amendment to Rule 26(d) on document production, and changes to Rule 34 on objections to document production requests.
