> Chevron ran to American courts and argued that Donziger helped secure this judgment by committing fraud. I believe the evidence of this was a video showing a minister and Donziger at a social gathering. The court ruled in Chevron's favor. This made the judgment unenforceable in the US.

If you're interested in this story, I would encourage you to read the full contents of the ruling in this US case. (https://theamazonpost.com/wp-content/uploads/Chevron-Ecuador...) It's long but relatively easy reading, and it contains a lot more evidence against Donziger's side of the story than a video of a social gathering. In particular, it seems absolutely unambiguous to me that his team blackmailed one of the Ecuadorian judges into giving him favorable rulings, implementing the theory repeatedly found in his personal notebooks that "the only way the court will respect us is if they fear us".
