General commercial disputes Tier 1

From a single office in Washington DC, Williams & Connolly LLP has established itself as one of the country's leading litigation firms. Its attorneys 'from the most junior to the most senior level, are extremely well prepared, diligent and practical'. Continuing its tradition of developing and promoting partners from within and rarely making lateral hires, the firm promoted several lawyers in 2018, including Steven Cady, Colette Connor and Christopher Mandernach. In the high-profile opioids investigations, a team led by Enu Mainigi has been serving as lead trial and national counsel for Cardinal Health in litigation and government investigations. The highly regarded Robert Van Kirk has defended The Carlyle Group in simultaneous actions in multiple countries concerning the collapse of Carlyle Capital Corporation in 2008; he and the team worked with local counsel to obtain a complete defense verdict for the company after a six-month trial at the Royal Court of Guernsey.

Appellate Tier 2

A ‘litigation powerhouse which is at the very top of the game’, Williams & Connolly LLP’s appellate practice attracts praise for demonstrating ‘excellence at the highest levels of the court system’ and for the fact that it ‘delivers superb results’. Former practice head Kannon Shanmugam departed to become chair of the appellate practice at Paul, Weiss, Rifkind, Wharton & Garrison LLP. Prior to his departure, Shanmugam led the team on multiple matters before the US Supreme Court. Among these, he represented the petitioner in Digital Realty Trust, Inc. v Somers, where he secured a 9-0 reversal of the Ninth Circuit’s prior judgment; the case concerned the scope of application of the anti-retaliation whistleblower protections provided under section 922 of Dodd–Frank. In Dahda v United States — a case questioning whether the federal wiretap statute requires the suppression of evidence obtained as a result of a wiretap order that exceeded the court’s territorial jurisdiction — the US Supreme Court voted 8-0 and sided with the team’s client Los Rovell Dahda. In another US Supreme Court highlight, the team represented respondent ION Geophysical Corporation in the case of WesternGeco v ION, concerning the interpretation of the general damages provision under the Patent Act. In E.F. Transit, Inc. v Cook at the Seventh Circuit, Amy Saharia presented arguments for Indiana transportation service company E.F. Transit, which sought regulatory approval to transport liquor; the Court ruled in favor of the client. Focusing on patent appeals, David Berl successfully represented MedImmune at the Federal Circuit, which dismissed patent invalidation claims submitted by AbbVie.

Hackney Wiegmann also played a key role in that case. Farina and Joseph Petrosinelli succeeded in narrowing the plaintiffs’ class at the class-certification stage in a case for Medtronic plc, which had seen a motion to dismiss reversed in a putative class action. Up-and-coming partner John Williams is also recommended. Kannon Shanmugam, who led the Digital Realty matter, joined Paul, Weiss, Rifkind, Wharton & Garrison LLP in Washington DC in January 2019.
