CCL launches Case Assessment & Interpretation (CAI) training course to help law enforcement with the presentation of cell site evidence at court

CCL Solutions Group has launched a specialist Case Assessment & Interpretation (CAI) Training Course designed to address a critical and evolving requirement in the presentation of cell site evidence at court.

Under the Forensic Science Regulator’s Code of Practice, cell site analysis relied upon in evidential material must be presented as expert evidence, including appropriate opinion on the meaning of telecommunications data within the context of a case. However, findings are still frequently presented as maps, tables or cell identifiers and treated as factual outputs, rather than as evaluative opinion evidence - an approach that carries significant evidential risk.

The course drills into the Case Assessment and Interpretation (CAI) model, focusing on the forensic reasoning and evidential standards required when cell site analysis transitions from investigative use to evidential application. It addresses the formation, evaluation and articulation of opinion evidence, ensuring that practitioners understand when expert inference is required, how it should be expressed, and how it can be robustly defended in court.

The programme is designed for:

• Law Enforcement Agencies delivering, or intending to deliver, cell site evidence in court
• Units transitioning from investigative use to evidential application
• Organisations working towards accreditation
• Analysts, managers and leaders responsible for evidential standards and risk

The training is delivered by recognised experts in cell site analysis from CCL’s accredited team, which has played a central role in establishing the forensic foundations of the discipline. The CAI framework taught is academically grounded, operationally embedded and court-tested.

CCL’s Cell Site Team Leader Kevin Weeks comments:

“Given that competence in opinion evidence is no longer optional but a statutory expectation, we believe the introduction of this new course is very timely. It provides a clear and defensible route to Code compliance for cell site analysis, delivered by practitioners who apply the same reasoning framework in accredited casework every day.”

With regulatory scrutiny increasing and evidential standards continuing to evolve, the course provides organisations with a practical and defensible pathway to meeting their obligations while strengthening the integrity of cell site evidence presented at court.
