How Did Judge Goss Begin Lucy Letby Trial Summing Up

The host reads and analyses the opening pages of Judge Goss's trial summing-up, finding three errors on the first page alone: conflating the brain and heart in describing how air embolism causes death, misattributing expert roles between Evans and Arthurs, and incorrectly describing Dr Dewi Evans as a neonatologist when he was a general paediatrician. The BAPM framework for neonatal risk assessment is discussed, with the host arguing that it was not properly applied to any of the index babies. The centrality of the shift chart to the prosecution's case is examined, and the host notes that the jury was directed to give significant weight to a statistical methodology that had never been scrutinised by a defence statistician. The structural dominance of Evans and Bohin across 92% of the medical evidence is identified as a flaw that should have been obvious to the court.
