Antero Resources Corp. v. South Jersey Resources Group, No. 18-1163 (10th Cir. 2019)Annotate this Case
Antero Resources Company and South Jersey Gas Company entered into an eight-year contract for Antero to deliver natural gas from the Marcellus Shale formation to gas meters located on the Columbia Pipeline in West Virginia. The parties tied gas pricing to the Columbia Appalachia Index.During performance of the contract, the price of natural gas linked to the Index increased. South Jersey contested the higher prices, arguing that modifications to the Index materially changed the pricing methodology, and that the Index should be replaced with one that reflected the original agreement. Antero disagreed. South Jersey then sued Antero in New Jersey state court for failing to negotiate a replacement index, and began paying a lower price based on a different index. Antero then sued South Jersey in federal district court in Colorado, where its principal place of business was located, for breach of contract for its failure to pay the Index price. The lawsuits were consolidated in Colorado and the case proceeded to trial. The jury rejected South Jersey’s claims, finding South Jersey breached the contract and Antero was entitled to $60 million damages. South Jersey argued on appeal the district court erred in denying its motion for judgment in its favor as a matter of law, or, alternatively, that the court erred in instructing the jury. After review, the Tenth Circuit affirmed, finding a reasonable jury could find South Jersey breached its contract with Antero because the Index was not discontinued nor did it materially change. Furthermore, the Court found no defects in the jury instructions.
