Thames and Chiltern
The Crown Prosecution Service (CPS) prosecutes cases that have been investigated by the police and other investigative organisations in England and Wales.
CPS Thames and Chiltern is one of 14 CPS areas across the country and we are responsible for prosecuting cases in Bedfordshire, Hertfordshire, Berkshire, Buckinghamshire and Oxfordshire.
We work in partnership with our three regional police forces - Hertfordshire Constabulary, Bedfordshire Police and Thames Valley Police - the courts, the judiciary and other partners to deliver justice. However, we are independent, and make our decisions independently of the police and other agencies.
Chief Crown Prosecutor Rose-Marie Franton is the head of CPS Thames and Chiltern, and she is supported on the legal side by Deputy Chief Crown Prosecutor Chris Derrick, who has responsibility for Crown Court cases, and Olivia Pearson, who has responsibility for magistrates' court cases. Robert Lucey is our Area Business Manager, who is responsible for business and operational delivery functions across our Area.
We have around 300 members of staff who are based in St Albans, Reading and Liverpool. Our workforce is made up of legal and operational delivery staff who all play a part in bringing criminal prosecutions to court. And we have an area business centre which includes specialist business support and administrative functions such as human resources, finance, communications and performance, all of which help to support the rest of the business.

Robert Lucey – Area Business Manager
Robert is our Area Business Manager and has responsibility for delivering the operational business across our Area.
As well as having oversight of all our business functions, Robert is responsible for staff and financial management, performance monitoring and the implementation of all our operational business systems.

Our Magistrates’ Court Team prosecutes offences including assaults, domestic abuse, criminal damage, possession of drugs, minor public disorder, minor traffic offences (excluding those dealt with by the police as police-led prosecutions), and commercial burglary.
This is not an exhaustive list, but the team is generally responsible for offences where the maximum permitted sentence for each offence does not exceed six months' imprisonment, or one year if two or more relevant offences are to be considered.
The Crown Court Team deals with cases such as murder, robberies, serious assaults, dwelling house burglaries, complex fraud, the supply and trafficking of drugs, and the most serious road traffic offences.
The serious nature of these offences mean they have to be tried before a jury or heard at the Crown Court because the magistrates’ court do not have sufficient sentencing powers for these crimes.
Our Complex Casework Unit (CCU) deals with the most complex cases in our area. The team of experienced specialist lawyers, paralegal officers and operational delivery staff work in collaboration with our three police forces to tackle serious, organised and cross-border crime across Bedfordshire, Hertfordshire, Berkshire, Buckinghamshire, and Oxfordshire.
Offences dealt with by the CCU include human trafficking, large-scale drugs importation, cold case murders, serious fraud and money laundering.
Our dedicated Rape and Serious Sexual Offences (RASSO) Team deals with rape cases (including attempted rape), child sexual abuse cases, serious sexual offences and allegations of perverting the course of justice or wasting police time which arise from false accusations of rape and domestic violence.
All our lawyers who work on rape and serious sexual offences prosecutions are specialists who are highly trained in the complexities of these cases, and they will prosecute them whenever our legal test is met.
