Recent First-Chair Jury Experience

  • Shelton v. Southern University Bd. of Supervisors (June 2012)
    Defense of the former Southern University board chairperson in this First Amendment retaliation case.

    Representation of a company owned by a renowned actor/director in this $18 million federal securities-fraud case arising from the Gulf oil spill. The plaintiffs were actor Stephen Baldwin and another investor. After a two-week trial in the Eastern District of Louisiana (New Orleans), the jury rejected the plaintiffs’ claims in their entirety and awarded them nothing. The court then denied the plaintiffs’ motion for a new trial and ordered them to pay the defendants over $60,000 in court costs. The U.S. Fifth Circuit affirmed the jury's verdict in its entirety.
