This article comments on a recent Home Office consultation about making forensic regulation statutory and the government's response to the Law Commission's recommendations for reforming the admissibility of expert evidence in criminal trials. By suggesting a duty of ‘omissive disclosure’ we offer a possible solution to concerns expressed to parliamentary inquiries about the ‘fragmentation’ of forensic science evidence and how reform, including regulation, might bear on (and support) individual scientific and medico-legal experts, as well as organisations and methods. We welcome the regulation initiative, but suggest that government policy also needs to address interrelated and systemic problems that beset the production of scientific and medico-legal evidence. We argue that these problems stem from fragmented policy making between and within government departments, possibly a similar fragmentation in jurisdictional rule-making and, reflecting their economic influence, the degree of responsibility vested inadvertently in the police and the CPS. We also suggest that regulation is not an alternative to implementing the Law Commission's recommendations, which together with forensic regulation should not be confined to criminal courts.

We do not know how often false positive reports are made in a range of forensic science disciplines. In the absence of this information it is important to understand the naive beliefs held by potential jurors about forensic science evidence reliability. It is these beliefs that will shape evaluations at trial. This descriptive study adds to our knowledge about naive beliefs by: 1) measuring jury-eligible (lay) perceptions of reliability for the largest range of forensic science disciplines to date, over three waves of data collection between 2011 and 2016 (n = 674); 2) calibrating reliability ratings with false positive report estimates; and 3) comparing lay reliability estimates with those of an opportunity sample of forensic practitioners (n = 53). Overall the data suggest that both jury-eligible participants and practitioners consider forensic evidence highly reliable. When compared to best or plausible estimates of reliability and error in the forensic sciences these views appear to overestimate reliability and underestimate the frequency of false positive errors. This result highlights the importance of collecting and disseminating empirically derived estimates of false positive error rates to ensure that practitioners and potential jurors have a realistic impression of the value of forensic science evidence.
