Ashley L. McMillian

Ashley McMillian has successfully litigated cases in federal and state courts across the country, winning nationally-recognized multi-million-dollar judgments for clients on the plaintiff’s side and defeating multi-hundred-million-dollar claims on the defense side. Ashley represents her clients in various types of complex commercial cases including oil and gas contract and regulatory disputes, electricity and power contract disputes, intellectual property disputes, fraud and RICO claims, major personal injury claims, securities fraud claims, partnership disputes, and many other commercial and financial matters.  In 2022, she was named in Lawdragon’s inaugural list of 500 Leading Litigators in America. She was named one of Lawdragon’s Leading 500 Plaintiff Financial Lawyers in 2020, 2021 and 2022. In 2019, Ashley was named a Rising Star in Energy Litigation by Law360. She has been a Recommended Lawyer by the Legal 500 in Energy: Oil and Gas Litigation (2019, 2020, 2021, 2022) and General Commercial Disputes (2021).

Ashley has tried numerous cases to judges, juries, and arbitrators and has been in charge of all attorney training at Susman Godfrey. She has significant pro bono experience, including work with nonprofit Kids in Need of Defense (KIND) in the representation of unaccompanied immigrant children at risk of gang violence if deported, and representation of women who are victims of sexual assault.

Ashley joined Susman Godfrey after clerking for a federal district judge in Austin, Texas. She grew up in Bloomfield Hills, Michigan.

Notable Representations

Rebellion Energy v. Liberty Resources Ashley represented Liberty Resources in a dispute over a bill in its $106 million energy deal with Rebellion Energy. Ashley’s team secured a significant win and settlement for Liberty after the Texas Court of Appeals for the First District affirmed the trial court’s decision that Liberty could not be forced to arbitrate the dispute and Liberty moved for summary judgment.

Apache Deepwater LLC v. W&T Offshore, Inc. Ashley and a team from Susman Godfrey won a $43,214,515.83 federal court jury verdict (and $48.5 million final judgment based on the jury’s $43.2 million verdict plus $2.5 million in attorneys’ fees and expenses and $2.8 million in prejudgment interest) for Apache Deepwater LLC against W&T Offshore based on W&T’s failure to pay its 49% share of the costs to plug and abandon three deepwater subsea wells in the Gulf of Mexico. Apache’s $48.5 million judgment was in addition to a $24.8 million partial payment from W&T to Apache 2½ months after Apache filed the lawsuit.

Spring Creek Exploration & Production Company, LLC v. Hess Bakken Investment II, LLC Ashley represented Hess Bakken against claims for an alleged breach of an area of mutual interest agreement concerning the Bakken shale play in North Dakota. The team obtained an early partial summary judgment dismissing the plaintiffs’ multi-hundred-million-dollar damage claim. Prior to winning summary judgment, Ashley successfully reduced plaintiffs’ damage claims by over $100 million by arguing and winning three motions to strike plaintiffs’ improper expert reports.

International Arbitration against PetroChina. Ashley represented two geologists as claimants in an international arbitration against state-owned oil companies PetroChina and Petronas arising from the non-payment of overriding royalty interests.  Shortly after the geologists filed their multi-million-dollar arbitration demand, PetroChina and Petronas paid them the entire amount demanded to the penny.

Trans Africa Technical Network (Nigeria), Ltd. v. TGS-NOPEC Geophysical Company, et al. Ashley represented TGS-NOPEC Geophysical Company and A2D Technologies, Inc. against claims seeking hundreds of thousands of dollars for breach of contract, breach of fiduciary duty, and an action on open account brought by Trans Africa Technical Network Nigeria, Ltd. (Tatnet). After Ashley deposed Tatnet’s president and filed a motion for summary judgment, Tatnet agreed to settle the case for only $10,000.

PersonalWeb Technologies, LLC v. Microsoft Corporation Ashley represented PersonalWeb Technologies in a patent infringement lawsuit against Microsoft Corporation. After a favorable Markman ruling, Susman Godfrey’s team defeated Microsoft’s motion to transfer the case from the Eastern District of Texas, and Microsoft filed a petition for a writ of mandamus to the Federal Circuit Court of Appeals again requesting transfer of the case. Ashley led PersonalWeb’s successful opposition to Microsoft’s petition, which was denied by the Federal Circuit. The case was settled within two months after the Federal Circuit issued its ruling. The amount of the settlement is confidential.

PersonalWeb Technologies v. Yahoo Inc. Ashley represented PersonalWeb Technologies in a patent infringement lawsuit against Yahoo, Inc. After a favorable Markman ruling and completion of discovery (including the Court granting PersonalWeb’s motion to compel), Ashley acted as lead counsel for PersonalWeb at mediation resulting in a confidential settlement right before trial.

IQ Holdings, Inc. v. American Commercial Lines, Inc. Ashley, along with Susman Godfrey’s Mark Wawro, obtained an $11 million judgment after trial in an appraisal action in Delaware Chancery Court brought on behalf of IQ Holdings, a minority shareholder of American Commercial Lines Inc. (ACLI). ACLI later appealed the decision to the Delaware Supreme Court, where the judgment was affirmed after argument before an en banc Supreme Court.

SM Energy Company, et al. v. Endeavour Operating Corporation Ashley represented Endeavour Operating Corporation against claims for breach of contract asserted by SM Energy Company, Potato Creek LLC, Open Flow Gas Supply Corporation, and SJ Exploration LLC. The case involved the applicability of federal regulations to natural gas pipelines and complex questions of historical Pennsylvania title law. After extensive discovery, in which Ashley argued and won an opposition to plaintiffs’ motion to compel, the case settled shortly before trial at a steep discount to the amounts of the claims asserted.

USA v. Kellogg Brown & Root Ashley joined Susman Godfrey’s Vineet Bhatia, Shawn Raymond, and Rick Hess in defending Kellogg Brown & Root (KBR) against a $300 million case brought by the United States. After claiming that KBR had violated the False Claims Act by billing the Army for costs associated with armed private security contractors in Iraq, the United States gave up by filing a voluntary motion to dismiss—with no strings attached. The federal district court ordered the dismissal of all claims against KBR.
