To call this a litigation about litigation about litigation is too simple. The case of Donziger v. Chevron has morphed into Chevron v. Donziger, which has morphed into Chevron v. Patton Boggs, which has morphed into Donziger v. Squire Patton Boggs.

It’s not even clear what to call the motion filed Wednesday night by Steven Donziger, the embattled U.S. counsel to the plaintiffs who won a $9.5 billion Amazon judgment against Chevron only to be labeled a fraud in a New York federal court judgment that is now on appeal. Is Donziger moving to unravel the settlement between Chevron and Donziger’s former co-counsel Patton Boggs? Or is he moving to scuttle the potential merger between Patton Boggs and Squire Sanders? A legal analysis suggests that the latter aim is more realistic.
