 e-Discovery software and service providers have been talking about proportionality almost non-stop ever since the 2015 amendments to the Federal Rules of Civil Procedure. Practitioners opine regularly on industry panels, webinars, and publications – but what is a commercial litigator’s perspective on proportionality?

Sean Burke and Ray Biederman, co-founders of Mattingly Burke Cohen & Biederman, LLP and Proteus Discovery Group, recently published a response to The New Framework released by the George Washington Law School in April. In this webinar, Sean, Ray, and David Horrigan discovery counsel and legal education director at Relativity, will discuss the New Framework from the perspectives of commercial litigators.
