Managing Director Bob Broxson provided expert reports, deposition, and trial testimony on behalf of Marathon Oil Co. in a high-stakes, precedent-setting contract dispute arising from a natural gas delivery impeded in 2021 by Winter Storm Uri.
A Texas federal jury rejected a $123.7 million breach-of-contract counterclaim filed by Koch Energy Services LLC, ruling in favor of Marathon’s force majeure defense related to natural gas deliveries during the historic storm. Marathon also prevailed on a partial summary judgment, with the jury requiring Koch to pay $9.8 million on Marathon’s breach of contract claim.
Mr. Broxson was retained by Ahmad Zavitsanos & Mensing to provide expert testimony challenging the claims made by Koch. Mr. Broxson provided direct testimony and was cross-examined on issues related to the common practices within the natural gas industry related to claims of force majeure in a six-day trial in Houston’s U.S. District Court for the Southern District of Texas.
The Secretariat team supporting Mr. Broxson on this matter included Adam Housel, Kaarle Rautio, and Tyler Anderson.
