Justin Rouse KC is an experienced and committed criminal Silk specialising in defending and prosecuting those charged with homicide, white collar crime, serious sexual offences and armed robbery.

Justin has amassed substantial experience over a 40-year career both prosecuting and defending and as defence counsel is cited as a leading KC in Legal 500 and Chambers UK. He has advised Parliament on statutory drafting.

Although he is now principally instructed to defend in serious crime, and has developed a strong practice representing young defendants, he acquired some of his skills as a former RASSO certified and grade 4 level prosecutor instructed in serious sex offences, heavyweight crime and complex fraud. He prosecuted the largest trial in the country to be staged under COVID conditions whilst leading Katrina Charles of 9BR Chambers against 14 defence counsel, resulting in murder convictions. 

He is currently prosecuting an Encrochat murder trial. He is regularly selected to defend in private sex cases with a strong success rate - winning all such cases in the last 3 years.

His forces background gives him unbridled insight when defending in Courts Martial cases. He has represented forces personnel and police officers across the UK and in Germany on serious offences including rape and grievous bodily harm with an outstanding success rate. He is also privately briefed in cases involving field sports and animal welfare allegations.

In addition to appearing in the Crown Court, Justin can be instructed to appeal a decision to the Court of Appeal and can advise both orally and in writing upon the prospects for success.

He is authorised to receive instructions directly from the public in private cases.
