Quinn Emanuel Urquhart & Sullivan has announced its 2026 partner class, with 12 lawyers elected globally — including London-based barrister James McSweeney. His promotion highlights the firm’s continued commitment to expanding its white collar, investigations and complex commercial litigation capabilities in the UK market.
James, who joined the firm in 2017, focuses on white collar criminal defence, corporate investigations and complex commercial disputes, and has represented clients before the English courts in high-stakes matters. His practice spans all aspects of corporate crime and investigations, as well as defamation and related commercial litigation. Prior to joining Quinn Emanuel, he was an associate at another US firm in London.
Announcing the new partner class, co-managing partner Michael B. Carlinsky said the cohort reflects the firm’s ability to develop ‘world-class trial lawyers across our global platform’ and ensures the firm continues to deliver ‘superior representation in our clients’ most critical disputes’. James’s elevation aligns with the firm’s broader strategy of deepening its London bench strength amid increasing demand for cross-border disputes and investigations expertise.
The London promotion sits within a globally diverse partner round spanning offices from Los Angeles to Munich, underscoring Quinn Emanuel’s continued international growth. James’s practice, with its blend of white collar, investigations and commercial litigation experience, adds further depth to the firm’s London offering as it positions for another strong year.
