Legal Tech: A Deep Dive Into the Tech Upgrades in Thomson Reuters' Westlaw Edge

By Zach Warren
August 01, 2018

Thomson Reuters is calling Westlaw Edge the company's most significant legal release since Westlaw Next in 2010, which makes sense — the features represent more than just an incremental product upgrade. Below is a non-exhaustive list of the features in the new Westlaw Edge product, as they were shown to Legaltech News and other media before the product's official release.

New Warnings for Invalid or Questionable Law

Case law may establish precedent, but precedent often doesn't last forever. In Westlaw Next, when a case overturned a previous ruling, the platform noted the overruled case with a red flag. What it didn't note, however, were the subsequent pieces of case law that were also invalidated by an overturned case but not explicitly mentioned in the new ruling.

Now, Westlaw Edge users will notice a new symbol: an orange triangle with an exclamation point. This means an “overruling risk,” which indicates that while a given case may not have a direct negative history, there are other issues at play, such as a cited case later being overruled.
