Since late 2010, Washington, D.C. law firm Patton Boggs has been poking a sleeping tiger. It has filed three peculiar federal lawsuits -- in its own name, not on behalf of any client -- against Chevron, the third-largest corporation in the United States. These cases have fared poorly; two were quickly dismissed, and a federal magistrate judge recommended tossing the third in March.
On Friday, the tiger awoke. Chevron (CVX) sought a federal judge's permission to bring counterclaims against the 455-lawyer firm for alleged fraud and deceit for its conduct in representing the Amazon Defense Front, which obtained a $19 billion environmental judgment against the oil giant in Lago Agrio, Ecuador, in February 2011. Chevron also seeks to charge the firm with "malicious prosecution" for having pursued its three lawsuits in bad faith. Chevron seeks to hold the law firm liable for any damages Chevron suffers from the Front's allegedly fraud-infested litigation, plus punitive and treble damages.
