A Texas appeals court has rejected a journalist’s attempt to unseal a 20-year-old deposition related to an infamous memo produced by Dallas-based Baron & Budd, in which the plaintiffs firm appeared to coach its clients to identify products they may have never been exposed to during asbestos litigation.

According to the recent decision by Houston’s First Court of Appeals, journalist and documentary filmmaker Christine Cole Biederman is seeking to obtain the 1997 deposition testimony Baron & Budd founder Russell Budd gave about the discoverability of the controversial memo.
