Thomson Reuters releases new version of online legal research platform Westlaw
Thomson Reuters has unveiled the latest iteration of Westlaw, its widely used online legal research platform.
Westlaw Precision was introduced Wednesday and is the company’s first new version in more than four years. It has six new features that Thomson Reuters said will allow lawyers to precisely tailor searches and reduce the time spent on research.
In a news release, Thomson Reuters said the precision research feature in the new product allows lawyers to easily find and sort cases by legal issues and outcomes, fact patterns, causes of action, party types and other criteria. In addition, lawyers can use an enhanced version of Westlaw’s citation-checking service, KeyCite, to find relevant material.
In addition to precision research, the platform offers five other features, according to Thomson Reuters, including KeyCite Cited With, a function that allows lawyers to see related cases that have been cited together. Other features show parts of cases that have been overruled in part and a graphical view of research history. There is also a feature to keep or hide cases based on relevancy and a research outlining tool.
In a news briefing Monday, Mike Dahn, head of product management at Westlaw for Thomson Reuters, said the product helps relieve issues lawyers face with retrieving irrelevant documents or missing relevant ones—issues that can make research difficult and time-consuming.
“We believe that this dramatically improves a lawyer’s ability to get what they want quickly,” Dahn said during the news briefing. “It saves them a lot of time and helps them reduce the risk of missing something important.”
Dahn said the new version means that lawyers will now have a precision research tool that allows them to find “the most on-point cases from the last 12 years” in addition to older, seminal cases, including those from the U.S. Supreme Court.
He noted that in its current form, the precision research tool has some limitations because of the vast amount of caselaw. Dahn said tagging all those cases was an “enormous undertaking,” and that developers were approaching caselaw topic by topic.
At launch, the precision research tool covers published cases in commercial law, federal civil procedure, federal discovery and evidence, federal remedies, federal class actions, employment, securities and antitrust.
Thomson Reuters said it expects to cover an additional 15 topics in 2022 and 2023 and more unpublished cases.
Dahn said the product would also be available as an upgrade for Westlaw Classic and Westlaw Edge customers at a “reasonable premium.”
Jeff McCoy, a Thomson Reuters spokesman, declined to disclose how much that the product would cost, writing in an email that “many factors” determine pricing.
