A major theme of the discovery-related 2015 amendments to the Federal Rules of Civil Procedure was the reintroduction of proportionality as a core aspect of the permissible scope of discovery. As amended, Federal Rule of Civil Procedure 26(b)(1) sets forth the scope of discovery, providing, "Unless otherwise limited by court order, the scope of discovery is as follows: Parties may obtain discovery regarding any nonprivileged matter that is relevant to any party's claim or defense and proportional to the needs of the case[.]" Since then, many courts have embraced proportionality, often as part of promoting a reasonable, cost-effective discovery process in line with the Federal Rules.
