What Is the New Evidence in the Lucy Letby Case?
The prosecution’s case relied primarily on medical evidence, handwritten notes, and the fact that Letby was present for every collapse. The handwritten notes, found at her home, included phrases like “I am an evil killer” and “I killed them on purpose.” There was no forensic evidence or eyewitness testimony of her committing the crimes.
Expert Witness Under Investigation
A critical development concerns the expert witness for the prosecution, Dr. Shoo Lee, whose 1989 paper on air embolisms was central to the case. In 2025, the British Medical Journal reported that Dr. Lee was under investigation by his employer during the trial, a fact not disclosed to the court. This has raised serious questions about the integrity of the evidence presented.
Dr. Shoo Lee, a neonatologist, provided testimony based on a 1989 paper about air embolisms in newborns. The jury was not informed that he was under investigation by his employer at the time of his testimony, as revealed by the BMJ in 2026.
Private Eye Coverage
The magazine Private Eye has published critical analyses of the case, focusing on statistical and medical evidence. Their coverage has amplified questions about the reliability of the prosecution’s case and how evidence was presented to the jury.
Why Are People Questioning the Lucy Letby Conviction?
The Innocence Campaign
A vocal campaign asserting her innocence has emerged. Supporters have submitted 31 reports from 26 experts to the Criminal Cases Review Commission (CCRC), arguing the conviction is unsafe due to disputed medical evidence. In February 2025, a global panel of 14 clinicians, led by Dr. Lee, concluded that no infants were murdered, stating deaths were due to natural causes or “bad medical care.”
CPS Admissions and Further Charges
The Crown Prosecution Service (CPS) admitted in August 2024 that evidence regarding staff movement logs in the first trial was incorrect. While this did not alter the verdicts, it added to concerns about the trial’s fairness. In January 2026, the CPS announced that Letby would not face further criminal charges regarding nine additional infants at Countess of Chester and Liverpool Women’s Hospitals, as the evidential test was not met. Cheshire Police expressed disappointment with this decision.
Will Lucy Letby Get a Retrial? Legal Status and Next Steps
As of mid-2026, the CCRC is still reviewing the application to refer the case back to the Court of Appeal. No timeline for a final decision has been given. The Court of Appeal has not scheduled a hearing, and it remains unclear if the case will be referred. Letby remains in prison serving her whole-life order.

Analysis: Why the Lucy Letby Case Remains Contested
The Lucy Letby case sits at a unique intersection of heinous crime, medical complexity, and growing legal scrutiny. While the jury’s verdict stands, several factors have kept the case in the public eye. The BMJ investigation into the prosecution’s key witness suggests a potential systemic failure in the trial process. The ‘Private Eye’ coverage has amplified questions about the statistical and medical evidence used. The CPS decision not to bring further charges closes one chapter but does not address the core doubts raised about the original trial. The parliamentary debate on Cheshire Police conduct adds a further layer of institutional concern. For those seeking a balanced understanding, it is crucial to separate established facts from ongoing legal challenges.
The jury’s verdict remains the only formal judicial finding. The challenges to the evidence, while significant, have not yet resulted in any court overturning the conviction. The CCRC review is the next critical step in the legal process.
