Thomson West Introduces Case Evaluator on Westlaw

EAGAN, Minn., Aug. 14, 2007 - Litigators have questions - about cases, about strategies, about any and all relevant information. Searching Westlaw for the answers - or even clues to the answers - just got easier. Thomson West today announced Case Evaluator on Westlaw, a new research feature that goes beyond a typical search and returns only the desired results unique to each query. West is a business within the Thomson Corporation (NYSE: TOC; TSX: TOC).

With Case Evaluator, for the first time litigators can build a fact base representing the outcomes of comparable cases - including verdicts, awards, relevant medical and expert witness data, and other criteria - and then generate Westlaw reports that can help sharpen legal strategies for the matter at hand. Case Evaluator enables users to select the criteria, jurisdiction and parameters so each report fits the unique type of case and fact profile.

"Case Evaluator gives a deeper view of cases in customized, concise, on-point reports," says Jeff Arvidson, director of Product Development, West. Using Case Evaluator, litigators can generate a full report or choose individual elements of the case. Litigators also can choose to run a national search or select a state jurisdiction for California, Georgia, New York, Ohio or Texas.

Case Evaluator allows litigators to:

• Evaluate potential cases.
• View verdict and settlement trends.
• Examine trial court motions and memoranda.
• Review appellate briefs, petitions and decisions.
• Use medical resources and illustrations.
• View analysis of experts included in verdicts and settlements, plus excerpts of their testimony.

"Attorneys often focus their litigation strategies by evaluating the potential for success given the facts of the case, and the dollar value of the case," Arvidson noted. "Litigators need to review whether similar cases in their jurisdiction have been decided or settled successfully, and analyze trends in order to see dollar ranges in similar cases - Case Evaluator provides that insight," he added.
