May 2026: Thirlwall Inquiry report delayed to at least September 2026 · six-baby inquests relisted to 2027 · CCRC review active · Shoo Lee Panel: no medical evidence of deliberate harm.
The Crown's trial narrative did not treat the unit's plumbing, sewage and water-infrastructure failures as a live clinical-differential explanation for the cluster of unexpected collapses. Infrastructure failures were not a central feature of the Crown's case.
Lorenzo Mansutti, a plumber employed to work on the Countess of Chester neonatal unit's infrastructure, gave defence evidence at trial documenting specific plumbing and sewage issues during the indictment period. His testimony addressed sewage backflow, waste-water contamination of clinical spaces, and the specific infrastructure failings the Datix record also documented. The significance of his evidence is not that he himself attributed any specific collapse to infrastructure — he did not — but that contemporaneous physical infrastructure failures existed on the unit during the indictment period, providing a documented differential for infection-mediated collapse that the Crown's narrative did not engage.
The plumber was on the unit. He saw what he saw. The Crown did not call him. The defence called him. His evidence went in.
Mansutti's defence evidence was heard. It was not a central feature of the Crown's closing speech, which focused on the prosecution's preferred narrative of direct harm rather than on infrastructure-mediated infection as a clinical differential.
The Panel does not adjudicate between competing infrastructure-vs-direct-harm differentials on the Crown's evidence; it finds case-by-case that no diagnostic criteria for deliberate harm are met and that natural-cause and sub-optimal-care differentials remain live. Infrastructure-mediated infection is within the differential the Panel's case-by-case findings leave open.
