This week’s Litigators of the Week, Alex Kaplan, Neal Manne and Weston O’Black of Susman Godfrey, have been working since 2013 to get their client Vitol out from under $3.89 billion in claims from the Puerto Rico Electric Power Authority.

In a suit originally filed in Puerto Rico in 2009, PREPA claimed Vitol violated Puerto Rico’s public-contracting law and misrepresented an affiliate’s involvement in a kickback scheme surrounding the UN Oil-for-Food Programme in Iraq and follow-on investigations. PREPA was seeking to rescind six fuel supply contracts with Vitol and get every penny it paid the company back.
