Oliver has twenty years advocacy experience and is a criminal law specialist. His knowledge and practice spans the range of criminal offences, however, his main areas of expertise are sexual offences, violence and drugs.

A direct access barrister, Oliver is able to accept instructions on behalf of members of the public as well as professional clients.


  • Criminal Bar Association.


  • Direct Public Access


  • Crime

    Oliver is particularly skilled at questioning young and vulnerable witnesses under the provisions of section 28 of the Youth Justice and Criminal Evidence Act 1999. He demonstrated this in a recent case where his careful questioning of a six year old child resulted in the conviction of her father for sexual abuse and a nine year prison sentence.

    In another serious and high profile case from Cheshire, Oliver prosecuted a man for attempting to murder his own child. He was found guilty and received a long term of imprisonment.

    This year Oliver has also prosecuted several county lines drugs cases. This has involved assimilating large amounts of data including cell site, telecommunications, ANPR, social media and CCTV in order to present a case that a jury would be able to follow.

    Oliver has built a strong defence practice. He is well regarded by those who instruct him for his ability to put clients at ease and explain the law in a straightforward way.

    In March 2019 he successfully argued that a youth accused of conspiracy to supply class a drugs from Liverpool to North Wales was the victim of modern slavery. It was the first time the new defence was used in North Wales and following the youth’s acquittal, he has provided guidance to other barristers and solicitors on the process.

    In May of this year, Oliver defended a Wrexham man accused of making explosives. After a persuasive plea in mitigation, the man received a suspended prison sentence.

    Also in May, Oliver secured a not guilty verdict for a man accused of severing another man’s hand with a machete; his meticulous questioning of the witnesses exposed a number of weaknesses in the prosecution case.

    Oliver is also committed to training and development. He has delivered talks to students at the Universities of Chester and Glyndwr and is involved in the assessment of police officers in the areas of surveillance, disclosure and using human intelligence sources.
