QHFSS DNA laboratory - ISO/IEC 17025 conformance and accreditation

This paper reviews evidence placed before a Commission of Inquiry (CoI) established by the State of Queensland, Australia, to consider the quality and reliability of DNA evidence. It also assesses whether the criticism levied in that report, of ISO/IEC 17025 being insufficient to assure the quality and reliability of DNA evidence, is warranted. The main conclusion drawn is that properly applied and embraced as a means of continuous improvement, conformance with ISO/IEC 17025:2017 alone is sufficient to assure the quality and reliability of the scientific outputs from a forensic science laboratory. Furthermore, it is clear from the observations and findings of the CoI and those recorded in this paper that the forensic science laboratory in question did not conform to ISO/IEC 17025:2017. Had it done so then the risk of the quality failures that led to the CoI would at least have been reduced and perhaps even avoided.
