During his brief stint representing attorney Steven Donziger, John Keker of Keker & Van Nest once predicted that Donziger would be “tethered to a stick like a goat” when he finally took the stand to face claims that he orchestrated a multibillion-dollar fraud against Chevron Corp. in Ecuador.

In a New York federal courtroom last week, Chevron began its grilling. Having virtually stripped Donziger of attorney-client privilege during four years of discovery, Chevron attorney Randy Mastro of Gibson, Dunn & Crutcher could roast Donziger with his diary entries, film outtakes, financial records and 19 full days of deposition testimony. “We meet again, Mr. Donziger,” began Mastro ominously.
