Representative Matters

Zachry Construction Corp. v. Port of Houston Authority

Trial counsel for plaintiff, a major construction contractor, in a three-month jury trial that the Texas Supreme Court later described as “hotly disputed at almost every turn.” The jury awarded plaintiff over $23 million on plaintiff’s claims concerning its construction of the defendant’s wharf facility and rejected the defendant’s $15 million counterclaims. In 2016, on remand to the court of appeals after a favorable result in the Texas Supreme Court, the verdict was affirmed in full.

Enterprise Texas Pipeline v. Energy Transfer Partners

Trial counsel for the defendant, a major pipeline company, in a four-week jury trial involving defendant’s operation of a major natural gas transmission pipeline.  The jury awarded plaintiff only 0.5% of the $400 million in damages it sought.  Final judgment on the 0.5% has not yet been entered.

Port Freeport v. Goldston Engineering, Inc. et. al.

Litigation counsel for plaintiff, a governmental entity, in its claims arising from the design and construction of its wharf facility in Freeport, Texas. Plaintiff collected approximately $19.6 million through the litigation and insurance claims process, with the litigation recovery representing over 100% of plaintiff’s actual damages.

B.L. Harbert International, LLC v. Chemtex International, Inc. et al.

Lead arbitration and litigation counsel for plaintiff, a major construction contractor, in its claims against the owners of one of the largest plastics plants in the world.  After initiating proceedings in both state court and arbitration, successfully forced defendants to pay plaintiff nearly the entirety of the amount claimed, over $7 million.

Enterprise Products Operating LLC, et al. v. Wood Group Mustang Inc. et al.

Litigation counsel for the defendant, a major pipeline construction design and inspection firm, in a suit filed by plaintiff alleging over $43 million in damage arising from defects in ten liquids pipelines in Port Arthur, Texas. After a series of hearings in which the Court struck over eleven of Enterprise’s experts, and after the firm filed a spoliation motion seeking dismissal of all claims, the case settled on favorable terms for the defendant.

Anadarko E&P Onshore, LLC v. Michigan 4-H Foundation et al.

Lead litigation counsel for the defendant, a non-profit charitable organization, in a suit filed against it by a major oil company. Acknowledging in its 59-page opinion that “this case is complex,” the federal district court granted our motion to dismiss the defendant from the case.

In re Carter Testamentary Trust

Lead trial counsel on behalf of a beneficiary of family testamentary trust against the trustee and the co-beneficiaries of the trust over the distribution of proceeds from the trust. After a bench trial, the client prevailed, entitling him to a favorable distribution of trust proceeds.

Union Oil Company of California v. Osprey Petroleum Company, Inc. and Pintail Petroleum

Litigation counsel for plaintiff in a case involving a dispute over oil and gas wells drilled in the Gulf of Mexico. Defendants counterclaimed and sought $350 million in damages from the plaintiff. Successfully obtained the dismissal of all of our opponents’ claims on summary judgment. The case thereafter was resolved favorably and confidentially.
