Marc represents plaintiffs and defendants in cases involving a wide array of civil claims in both trial and appellate courts. His meticulous attention to detail, knowledge of relevant changes in the law, and ability to craft highly persuasive briefs have led to a particularly strong record of success on appeal.

For example, Marc recently represented a steel distributor at trial and during appeal in a Sherman Act antitrust case against several large steel distributors and manufacturers arising from defendants’ efforts to prevent a new distributor from entering the market. The jury returned a verdict in favor of his client, who received a judgment of more than $160 million after the imposition of treble damages, costs, and attorneys’ fees.

In addition to his antitrust work, Marc has achieved successful outcomes in disputes relating to oil and gas issues, securities fraud, product liability, trade secret misappropriation, construction law, breach of contract, fraudulent transfer, breach of fiduciary duty, defamation, negligence, and wrongful death, among others.

Before joining Hicks Johnson, Marc was a partner at Yetter Coleman and, previously, an appellate lawyer at Weil, Gotshal & Manges. Prior to entering private practice, he served as a law clerk to the Honorable Edith H. Jones of the United States Court of Appeals for the Fifth Circuit.

Notable Experience

  • Successfully represented one of the largest oil and gas producers in West Virginia in a recent appeal to the U.S. Court of Appeals for the Fourth Circuit that addressed the application of the Tawney (Estate of Tawney v. Columbia Natural Resources LLC) rule, which remains a contentious issue in the state’s oil and gas law. Ultimately, the court’s decision awarded drillers the right to claim post-production deductions when calculating gas royalties “at the wellhead” under West Virginia law. (Read media coverage here.)
  • Representing a large mineral owner in a lawsuit (and resulting appeal) against a mining company involving the mining company’s burying of millions of tons of iron resource under stockpiled mining waste from a nearby iron mine in Minnesota. Marc and his team recently secured a dismissal in Minnesota Supreme Court in this ongoing $10 million-plus case, which is now proceeding back in trial court.
  • With more than $60 million in controversy, won an appeal on behalf of underwriters in connection with a case that arose after a well blowout in the Gulf of Mexico.
