Hertfordshire falls within the CPS Thames and Chiltern Area, one of 13 CPS Areas across England and Wales, which prosecute people charged with a criminal offence.

CPS lawyers review the evidence gathered by the police and decide whether the case should go to court.

Responsibilities include:

  • Advising the police on possible prosecutions
  • Reviewing cases submitted by the police and deciding on the charge
  • Preparing cases for court
  • Prosecuting cases at Crown Courts and Magistrates' Courts

Cases are prosecuted firmly, fairly and effectively when there is sufficient evidence to provide a realistic prospect of conviction and when it is in the public interest to do so.


In the financial year to March 2016, CPS Thames and Chiltern prosecuted 7,120 Hertfordshire defendants in the Magistrates' Courts and 1,450 defendants in the Crown Courts. The conviction rate for this period was 82.5% in the Magistrates' Courts and 79.9% in the Crown Courts.

It should be noted that a large number of low complexity cases (including many traffic cases with guilty pleas) were prosecuted by the police this year and are not now included in these figures.
