A federal judge has approved a request by the oil giant Chevron to subpoena the personal Internet information of more than 100 people, including environmental activists, journalists and lawyers. Chevron is seeking the records as part of its effort to bring a conspiracy case against the plaintiffs, who have won an $18 billion judgment against the company for polluting Ecuador’s rain forest. None of the individuals are parties to the lawsuit against Chevron, but Chevron says they may be directly or indirectly involved. Chevron is seeking the IP addresses that show the time and location of every single login over a nine-year period.
