Judge Enforces Chevron's Subpoena of Penn. Lawyer

Joseph Kohn of Kohn, Swift & Graf forfeited his right to attorney-client privilege by letting a documentary crew film strategy sessions, U.S. District Judge Jan DuBois found.

Kohn and another attorney, Steven Donziger, helped Ecuadorians sue Chevron over damage to their community from 30 years of drilling in the country conducted by Texaco, which became a Chevron subsidiary in 2001.

In a bid to draw international attention to the case, and mount pressure on Chevron, they also invited filmmaker Joseph Berlinger to document the rainforest devastation.
