Elisabeth Acker – 23ES ‘Elisabeth has an excellent analytical ability to understand and highlight the key issues in a case. Her empathetic and kind nature ensures that she is a perfect advocate for cases involving youths or extremely vulnerable witnesses and complainants. Her advocacy is also exceptional.’ 

23ES is ‘a very well established and highly respected set’ with a ‘breadth of talent‘. Prior to her December 2023 appointment to the Circuit Bench in November 2023, Allison Hunter prosecuted a thirteen-defendant drug conspiracy involving 1000kg of cocaine in a case featuring Encrochat evidence. Elisabeth Acker prosecuted alone in a case in which the defendant was convicted for importing and selling endangered species, specifically jewellery containing elephant parts, contrary to CITES – the matter involved arguments on the adequacy of expert opinion, the appropriate method of scientific testing, the admissibility of evidence obtained from abroad, and on the statutory interpretation. James Bloomer was instructed for the defence in the case of a young man of previous good character accused of a bomb hoax and possession of an imitation firearm following a bungled attempt at a bank robbery – the case turns on the psychiatric evidence, assessing whether he was in the grip of a psychotic episode at the relevant time as well as the admissibility of a quasi-confession given during interview.
