Protocol: using casework material for validation purposes

A protocol on the use of casework material for validation purposes.



The thorough validation of forensic science methods normally requires the use of material from real cases. The use of such material gives rise to a number of issues and potential risks.

The Forensic Science Regulator has agreed a protocol with the Director of Public Prosecution and the National Police Chiefs’ Council to:

  • simplify the process for approval of the use of casework material
  • establish processes to address the issues and control the risks which result from such use
