Sonn Macmillan Walker Maintains Band 2 Ranking for Extradition in Chambers and Partners 2026

16 October 2025

We are pleased to announce that Sonn Macmillan Walker has once again been ranked in Band 2 for Extradition in the Chambers and Partners 2026 guide, reaffirming our long-standing position as one of the UK’s leading firms in this complex and specialist area of law.

Our Extradition department is headed by Katy Smart, a Band 1-ranked practitioner whose expertise and leadership continue to set the standard in this field. Under Katy’s guidance, the team has built a reputation for excellence in defending individuals facing extradition.

Our extradition team is trusted to advise and represent clients in some of the most challenging and high-profile extradition cases, including those involving politically sensitive allegations, human rights considerations, and novel legal arguments. We regularly appear in proceedings before Westminster Magistrates’ Court, the High Court, and in cases attracting international attention.

Maintaining our Band 2 ranking reflects the consistency, expertise, and strategic depth that our team brings to each case, as well as the trust placed in us by clients, counsel, and peers.

This continued recognition is a testament to the strength of our extradition practice, built over many years of dedicated work on both incoming and outgoing requests from a wide range of jurisdictions.

Congratulations to our outstanding extradition team on this well-earned recognition in the 2026 edition of Chambers and Partners.
