Two federal courts have rejected the appeals of consultants seeking to quash Chevron's subpoenas in a $27 billion environment contamination lawsuit against the oil giant in Ecuador. The 5th Circuit in Houston ruled that 3TM must submit to a limited foundational deposition, while a federal judge in San Diego ruled that E-Tech International, a New Mexico corporation, and William Powers, a petroleum engineer, must produce documents and give deposition testimony...[T]he consultants appealed the subpoenas on the grounds of privilege and jurisdiction, but both courts found little evidence to support the consultants' arguments. [also refers to E-Tech Intl., Stratus]
