Notable cases

R v A and H: Led by Mark Connor in a three-week historic child sexual abuse case which concluded with a successful prosecution against defendant one for multiple serious sexual offences and against defendant two for offences of doing acts tending and intended to pervert the course of public justice and child cruelty. Defendant one was sentenced to life imprisonment with a minimum term of 24 years and defendant two received a sentence of 10 years imprisonment. The case concerned offences of the utmost seriousness committed over a period of many years and involved a complex police investigation.
