“Effective as an advocate and good at explaining ideas to the court.”  “He has a real eye for detail, and is incredibly approachable and friendly as well.” (Chambers and Partners 2017)

Appointed Queens’ Counsel in 2014, Jonathan is ranked in Chambers and Partners 2017 in Administrative and Public Law, and POCA Work and Asset Forfeiture. He has a wealth of experience handling unusual, sensitive or controversial matters, especially in the fields of asset recovery, mutual legal assistance, national security, human rights, confiscation, tax and duties, law enforcement, extradition, inquests and immigration, and wherever criminal law interfaces with public law. Before taking Silk, Jonathan was a grade 4 prosecutor.

“Hall is an established player who is well beyond his year of silk in terms of his gravitas and the cases he deals with.” “He’s really clever, he writes well and he’s a great advocate.” “A powerful advocate who can see both sides of an argument and really fine-tune his approach.”

Chambers and Partners 2017

In recent years he has acted in high profile cases such as the ongoing Undercover Policing Inquiry, the recovery of assets stolen by General Abacha, the 7/7 Brecon Beacon and Litvinenko Inquests, civil claims arising out of the shooting of Mark Duggan, and damages claims against the intelligence services.

Jonathan is familiar with the demands of large organisations and the strategic implications of litigation and investigations, and is frequently instructed to advise private clients and public bodies on issues of RIPA, cybercrime and data protection, law enforcement, regulatory crime, national security and on novel and difficult issues of fact and law.
