Tom Weisselberg KC and Jane Mulcahy KC have been elected as the new joint heads of Blackstone Chambers for a five-year term, commencing on 17 October 2022.

Tom and Jane previously led, respectively, Chambers’ commercial and employment groups and are longstanding members of the set’s management committee. Tom is a highly rated silk with a practice that spans commercial litigation, civil fraud, media and entertainment and public law. Jane is particularly noted for her expertise in both employment and sports litigation and deals with complex and difficult cases concerning employee competition, whistleblowing and discrimination.

They replace outgoing heads Monica Carss-Frisk KC and Tony Peto KC, who led Blackstone Chambers for 10 years from January 2012. Both will continue in full-time practice. During their tenure Blackstone Chambers grew from 87 tenants, including 37 silks, to 121 tenants today, comprising 59 King’s Counsel and 62 junior barristers. The set boasts top-rated expertise across a huge range of specialist areas, encompassing arbitration, commercial, civil fraud, public and regulatory, employment, international, competition, sport, telecoms, tax, sanctions and financial services.

During the last four years, Monica and Tony have overseen a significant renovation and expansion project of Blackstone Chambers’ premises that was completed in Summer 2022. This comprised the development of new Grade II listed premises in Garden Court, followed by the redevelopment of Blackstone House. The latest work includes an extension to the sixth floor and the creation of a new four-storey atrium to connect the buildings. 

On completion, Blackstone Chambers’ significantly expanded space now includes a brand new clerks' room, additional offices and meeting rooms, and state-of-the-art conference facilities, all within two minutes’ walk of the Royal Courts of Justice.

The culmination of this project, which has been run jointly by Middle Temple and Blackstone Chambers, marks one of the most significant building projects completed by any London set, creating a unique and contemporary new home in historic Middle Temple. 

In a joint statement, Tom and Jane said: “We want to thank Monica and Tony for their incredible leadership over the last 10 years. We are excited to be taking on the roles now, in a fantastic new building and surrounded by such a great team of staff and colleagues. We will work hard to continue Chambers’ success, focusing on developing the very best advocates in a friendly and open environment where both they and their practices can thrive.”
