Check Challenges to An Expert's Past Testimony.  Order a Challenge History Report from TASA.

Avoid Surprises at Deposition or Trial

Have there been challenges to your expert's or your opposing expert's past testimony, where a "gatekeeping" standard or rule has been cited and/or the expert's qualifications or methods challenged or strongly criticized by the court? A Challenge History Report (CHR) from TASA can be a vital part of your expert witness due diligence strategy.

What Does a Challenge History Report (CHR) Include?

The Challenge History Report compiles reported and many unreported decisions involving an expert's challenged testimony. When challenges appear in the search results, your CHR will provide case summaries with major reasons for admission or exclusion of testimony, and, where applicable, all supporting documents, such as briefs, motions to exclude, and transcripts, for the one low price of $45.  Many of the cases and data elements our system provides are not found in standard case law systems. The CHR draws from an integrated database that compiles both federal evidentiary gatekeeping decisions, such as Daubert, Frye, Joiner, Kumho, Scheffer, and Weisgram, and Uniform Rules of Evidence for state and federal courts dating back to 1993.  For a complete list of federal and state gatekeeping standards that the CHR tracks, please click here.
