Context
The Court of Appeal (Criminal Division) refused Lucy Letby’s application for leave to appeal against conviction on 24 May 2024. The judgment addresses the specific grounds then advanced by Ms Letby’s legal team, which were principally that the statistical presentation of the shift-rota chart was unduly prejudicial and that certain expert evidence ought not to have been admitted in the form in which it was.
The application was heard before the International Expert Panel convened by Dr Shoo Lee reported in February 2025, and before the majority of the independent expert reports subsequently filed with the Criminal Cases Review Commission. The Court of Appeal did not have, and could not have had, sight of the post-February-2025 material. That is why the CCRC is now the relevant body.
