Expertise
- R v Elias Morgan – Leading a three counsel prosecution team in a case involving a firearms execution in retaliation for the conduct of a prison officer in the course of his duty.

The case also relied upon contested GSR, vehicle identification, facial recognition, body mapping, DNA, vehicle telematics and copious CCTV evidence. https://www.bbc.co.uk/news/articles/c9d0d63pnw2o
