Sir James Eadie KC is one of the UK's leading advocates, with a practice spanning public and regulatory, commercial, EU and international law. 

The Lawyer's Litigation Tracker's analysis has found James to be the top-ranked barrister at the Bar since 2015, by volume of court appearances, undertaking twice the share of court work of any other ranked barristers. 

James was appointed First Treasury Counsel in January 2009, breaking the tradition of appointing Junior Counsel to this role. He had previously been Junior Counsel to the Crown, Common Law (1997-2008); alongside a private commercial and regulatory practice.

In the profession, he is called the ‘Treasury Devil’. As such, he is the KC to whom the Government turn first for their major pieces of advice and litigation.

He advises the Government across the entire range of Government activity – from terrorism to tax.  He has acted in much of the major litigation brought against the Government (frequently in the Supreme Court and European Court of Human Rights).

He was named Human Rights and Public Law Silk of the Year at the Chambers UK Bar Awards 2017; and again in 2021. He has been regularly named in The Times Law 100 listing the most influential lawyers in Britain.

The Legal Directories have listed him as both one of the Stars of the Bar and consistently in the first tier of Public and Administrative, and Human Rights, KCs. He is also currently ranked for his expertise in Immigration, Indirect Tax, Data Protection and EU law. They said: 

CHAMBERS AND PARTNERS, 2021/2022

Stands head and shoulders above the rest.

He's mind-blowingly good, he just grasps everything immediately… He is one of the finest of his generation … He can run the most difficult cases and technically is second to none… His demeanour and presence in court are statesmanlike and very impressive.”

"He is a brilliant individual and a towering giant at the Bar… By far the best public law silk at the Bar.” 

LEGAL 500, 2021/2022 

“He is the best Supreme Court advocate with more experience before the court than anyone else at the Bar.”

“A tremendous silk… Simply phenomenal.”

"A stellar barrister and an excellent advocate.”
