Widely acknowledged to rank among the leading appellate practices in the US, Gibson, Dunn & Crutcher LLP fields an enviably deep bench that is well dispersed across the country, leveraging platforms in key states such as California, Texas, and Washington DC. Among its recent high-profile cases, Washington DC-based Thomas Hungar scored a unanimous win at the US Supreme Court for Slack Technologies in a landmark case discussing direct listings. Hungar also teamed up with the labor and employment practice to successfully represent UBS before the Second Circuit in a Sarbanes-Oxley whistleblower retaliation case. The national group is co-chaired by former Principal Deputy Assistant Attorney General Thomas Dupree in Washington DC, who has argued more than 100 appeals; Dallas-based department co-head Allyson Ho, who is set to represent Truck Insurance Exchange before SCOTUS in a high-profile bankruptcy-related case; and Los Angeles-based Julian Poon. The formidably strong practice also draws on Theodore Boutrous in Los Angeles whose impressive appellate track record spans civil, constitutional and criminal cases; Miguel Estrada, who has argued twenty-four cases before SCOTUS; and global litigation co-chair Helgi Walker. Former District Judge for the District of Maryland George Hazel recently joined the team. All lawyers mentioned are in Washington DC unless otherwise stated.
