CPS Complex Casework Unit: How Serious Criminal Cases Are Prosecuted
Introduction
When someone is investigated for a serious criminal offence, their case may be handled by a specialist prosecution team within the Crown Prosecution Service (CPS). One such division is the CPS Complex Casework Unit, which deals with particularly serious or legally complicated criminal matters.
Cases handled by this unit often involve large volumes of evidence, sensitive allegations, or complex legal issues. As a result, they are prosecuted by specialist lawyers with experience in serious crime.
For individuals facing allegations connected with these investigations, understanding how the Complex Casework Unit operates is essential. These cases are often high-stakes and can involve lengthy investigations and complex court proceedings.
What Is the CPS Complex Casework Unit?
The Complex Casework Unit is a specialist department within the Crown Prosecution Service responsible for prosecuting particularly challenging criminal cases.
These cases may involve:
- significant evidential complexity
- multiple defendants
- extensive digital or financial evidence
- serious or sensitive allegations
Prosecutors within the unit are experienced lawyers who deal regularly with cases requiring advanced legal analysis and careful case management.
Their role is to review evidence gathered by investigators and determine whether the case meets the legal threshold for prosecution.
The CPS operates independently of the police and must apply strict legal standards before criminal charges can be authorised.
Further information about CPS decision-making can be found in the Code for Crown Prosecutors published by the Crown Prosecution Service.
What Types of Cases Are Handled by the Complex Casework Unit?
The CPS Complex Casework Unit deals with a range of serious criminal offences that require specialist legal oversight.
Serious Sexual Offences
Some cases involving serious sexual allegations may be referred to specialist CPS units where the evidence is complex or involves multiple complainants.
These cases may involve:
- extensive digital evidence
- historic allegations
- multiple witnesses
- complex evidential issues
Large-Scale Fraud and Financial Crime
Complex fraud investigations often involve large volumes of financial documentation and digital records.
Cases may include:
- corporate fraud
- investment fraud
- conspiracy to defraud
- money laundering
These investigations frequently require detailed analysis of financial transactions and expert evidence.
Complex Violent Offences
Serious violent offences involving multiple suspects or complex factual circumstances may also be referred to specialist prosecutors.
Examples may include:
- organised criminal violence
- conspiracy offences
- complex homicide investigations
Such cases often involve detailed forensic evidence and lengthy investigations.
Why Are Cases Referred to the Complex Casework Unit?
Not every criminal case is handled by the Complex Casework Unit.
Cases are usually referred when they involve factors such as:
- large volumes of evidence
- complex legal issues
- multiple defendants
- serious or sensitive allegations
- extensive financial or digital analysis
The aim is to ensure that these cases are managed by prosecutors who have the expertise and resources required to deal with them effectively.
How the CPS Decides Whether to Prosecute Serious Offences
Before any criminal charge is authorised, the CPS must apply the Full Code Test set out in the Code for Crown Prosecutors.
This test has two stages.
The Evidential Stage
Prosecutors must determine whether there is sufficient evidence to provide a realistic prospect of conviction.
This means an objective assessment of whether a properly directed jury or magistrates would be more likely than not to convict.
The Public Interest Stage
If the evidential test is satisfied, prosecutors must then consider whether a prosecution is required in the public interest.
Factors considered may include:
- the seriousness of the alleged offence
- the circumstances of the suspect
- the impact on victims or the wider public
Detailed guidance on this process is available on the CPS website

- determining whether criminal charges should be authorised
- preparing cases for court proceedings

These prosecutors often work closely with investigators, forensic specialists, and other legal professionals.
Because of the complexity of these cases, investigations and prosecutions may take significant time to progress.
