Prosecution position
Executive conduct formed no part of the case against Letby and does not bear on the verdicts.
Expert challenge / post-conviction reading
The Inquiry record documents the decisions taken in 2015-2016: staffing levels, the response to consultant concerns, communications with regulators, the grievance process and the apology-letter sequence.
What remains uncertain
Three former senior executives were arrested in July 2025 on suspicion of gross negligence manslaughter and one was re-arrested on 23 April 2026 on suspicion of perverting the course of justice. No charging decisions have been announced, and an arrest is not a charge.
Common questions
