Why the template matters
Mass miscarriages of justice rarely correct themselves. A defendant acting alone, without organisational support, has limited institutional leverage against a trial verdict. What the Post Office Horizon case demonstrated, and what the Bates organisational template codifies, is the structured combination of components that together can shift a settled verdict: organised defence, independent technical experts, litigation, journalism, parliamentary engagement, sustained effort, and eventual mass public recognition.
The Letby effort is, in 2026, most of the way through this structured template. This page walks through each component and maps the Letby effort onto it.
Component 1 — organised defence
Horizon: Alan Bates founded the Justice for Subpostmasters Alliance in 2009, coordinating sub-postmasters who had been individually pursued.
Letby: Mark McDonald KC took over the post-conviction legal representation after the May 2024 Court of Appeal refusal. The October 2025 CCRC application is the coordinated-defence product.
Component 2 — independent technical experts
Horizon: Independent forensic IT experts (Jason Coyne and others) exposed the Horizon system’s unreliability. Their reports were the technical basis for the 2019 High Court judgment.
Letby: The Shoo Lee International Expert Panel (14 senior international neonatologists), the Joint Expert Witness Insulin Report, the independent paediatric-pathology re-readings, and the statistical critiques by Prof. Richard Gill and Prof. Peter Green are the technical-expert basis. See our Panel consensus evidence.
Component 3 — litigation
Horizon: The 2017–2019 group litigation Bates & Others v Post Office in the High Court produced the 2019 judgment that Horizon had been unreliable.
Letby: The October 2025 CCRC application is the litigation. If referred, it goes to the Court of Appeal. See our Court of Appeal referral mechanics analysis.
Component 4 — sustained journalism
Horizon: Nick Wallis’s sustained coverage for Private Eye, BBC Radio 4 and his 2021 book produced the public record that eventually fed into mass public recognition.
Letby: Dr Phil Hammond’s Private Eye M.D. column is the direct counterpart. Rachel Aviv’s New Yorker piece is the major international long-form counterpart. Peter Hitchens’s Mail on Sunday columns are the right-of-centre counterpart. Together they form the Horizon-template journalism layer.
Component 5 — parliamentary engagement
Horizon: Sir David Davis MP, James Arbuthnot, Lord Arbuthnot of Edrom and others raised the Horizon case in Parliament across multiple years.
Letby: Sir David Davis MP’s November 2024 Commons adjournment debate. Lord Sumption’s November 2025 broadsheet intervention. The April 2025 Bar Council letter. The parliamentary engagement component is active.
Component 6 — sustained effort over years
Horizon: Twenty years from initial prosecutions to mass exoneration. Sustained, not episodic.
Letby: The CCRC process alone is typically 2–4 years. Full resolution to Court of Appeal judgment plausibly 4–6 years from October 2025. Sustained effort is the defining feature; the Letby template is in the early years of it.
Component 7 — mass public recognition
Horizon: The January 2024 ITV drama Mr Bates vs The Post Officetriggered mass public recognition. A statutory exoneration process followed in 2024.
Letby: The public-recognition component is still building. The Panel report had significant press reception in February 2025. Sustained coverage continues. A cultural-event trigger of the Mr Bates kind has not yet occurred.
What the template tells us about timescales
The Horizon template took twenty years from first prosecutions to mass exoneration. The slow pace is a structural feature of mass-miscarriage correction, not a judgment on the merits. The Letby effort started its organised-defence phase after the May 2024 Court of Appeal refusal. On Horizon timescales, resolution is likely approximately 2028–2030 — assuming the template holds.
This is a prediction, not a guarantee. Individual cases differ. The Letby effort has the advantage of starting from a more institutionally-supported expert-evidence base than Horizon had at the same stage. But it has the disadvantage of running against the full weight of two whole-life orders and the institutional inertia those carry.
