R v O, 2017

Defending an attempted murder allegation deriving from a group knife attack in a night club. Sean ran a series of legal arguments as to the admissibility of forensic and medical evidence that ensured that in due course the prosecution offered no evidence on the attempted murder and accepted a plea to ABH with the defendant receiving a non-custodial sentence.

R v S, 2016

Charged with murder, Smith was the only one of five defendants to be acquitted after a five-week trial.
