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 case at trial was presented as the mutually-corroborating weight of many distinct strands of evidence: medical causation, statistical pattern, handwritten notes, Facebook searches, handover sheets, search history. The jury was asked to find that the combined weight satisfied the criminal standard of proof.
Independent review identifies that the strands are not independent but structurally circular. Dr Evans's causation opinion rests on the premise that a cluster requires a criminal explanation. The shift-rota chart was constructed by selecting events partly because Letby was there. Dr Bohin's second-opinion evidence worked within the methodological frame Evans had established. The handwritten notes were produced after the consultant-team suspicion had been communicated to her. The Facebook-search curated subset was selected in retrospect from a much larger denominator. The handover sheets were retained under the NHS confidentiality framework the same way many nurses retained theirs. Each strand, examined individually, does not establish what the Crown claimed; the cumulative argument only works if the strands are treated as mutually corroborating independent evidence, which on structural analysis they are not.
If each strand depends on the others for its meaning, the combined weight is not the sum of independent evidences. It is the same proposition repeated in several registers.
The Crown's closing speech presented the strands as mutually corroborating. The jury was not systematically walked through the circularity analysis independent experts have since applied.
The Panel's case-by-case medical review treats each count on its own medical merits without relying on the pattern argument. That approach — each count independently — produces the conclusion that medical evidence of deliberate harm is absent in every case reviewed.
