Lawyers for British nurse Lucy Letby, convicted of killing seven babies and attempting to murder eight more while working in the neonatal unit at the Countess of Chester Hospital, have launched a bid to overturn her conviction.

Letby, who was sentenced to 15 life terms without parole in 2023, maintains her innocence.

Her defense team, led by lawyer Mark McDonald, presented new findings from a group of 14 international medical experts, including University of Toronto Professor Emeritus Shoo Lee, who concluded that the medical evidence presented during the trial was flawed.

The experts claim that there is no evidence of murder, suggesting instead that the infants’ deaths resulted from medical mistakes or failures at the hospital.

The experts argue that their research was misused during the trial, which contributed to a wrongful conviction.

Letby had been accused of injecting the babies with insulin, air, or force-feeding them milk, but the experts assert these claims were unfounded.

The Criminal Cases Review Commission (CCRC), which investigates potential miscarriages of justice, is currently reviewing the new application submitted by Letby’s legal team.

Meanwhile, a public inquiry and additional police investigations into Letby’s actions are ongoing.

The CCRC has stated that it cannot predict how long its review will take.

The conviction has sparked widespread debate, and the case remains under scrutiny by both legal experts and the public.
