Lucy Letby Miscarriage of Justice - Insulin Cases Series Part 1 The Context

The insulin cases are identified as the 'locomotive' of the Letby conviction — the claims most likely to have driven the verdict. Historical parallels are drawn with Deborah Windsor (2000) and Colin Norris (2008), both cases involving alleged insulin poisoning where convictions were later questioned. The Law Commission's 2011 recommendations to improve expert evidence standards in criminal courts are noted but were rejected by government. The exoneration of Kathleen Folbigg in Australia is cited as a relevant precedent for wrongful conviction in child death cases. The pending appeal of Colin Norris is identified as a live test case for whether British courts can correct systemic errors in expert witness-dependent prosecutions.
