Oliver was appointed First Senior Treasury Counsel in 2021 and is on the Attorney-General’s list of approved counsel. He has a reputation for detailed preparation, exceptional advocacy and is “an especially good cross-examiner”. He is recommended as one of the star individuals in the Chambers UK Guide and one of the leading silks in the Legal 500.
He divides his practice between working at the highest level in the criminal sphere; appearing in public inquiries and inquests where the government, the military or the security services are often involved; and specialising in complicated and serious quasi-criminal and regulatory work.
