LUCY LETBY CASE TAKES ANOTHER TURN: 3 YEARS AFTER HER CONVICTION, THE LEGAL BATTLE IS STILL NOT OVER

Three years after Lucy Letby was convicted in one of Britain’s most closely watched criminal cases, the former neonatal nurse remains behind bars — but the debate surrounding her convictions has entered a new chapter.

Letby was convicted of murdering seven newborn babies and attempting to murder seven others at the Countess of Chester Hospital between 2015 and 2016. She is serving 15 whole-life sentences at HMP Low Newton.

But while her convictions remain firmly in place, her legal team is continuing to challenge the evidence.

A NEW LEGAL REVIEW IS UNDERWAY

In February 2025, Letby’s lawyers submitted an application to the Criminal Cases Review Commission, the independent body that investigates possible miscarriages of justice in England and Wales.

The CCRC confirmed that it had received the application and said work had begun assessing the case. The commission stressed that its role is not to decide whether someone is innocent or guilty, but to determine whether a case should potentially be referred back to an appeal court.

That review remains significant because Letby’s defense says new medical evidence challenges parts of the prosecution’s interpretation of what happened to the babies.

 THE HOSPITAL INVESTIGATION HAS ALSO CONTINUED

The controversy has expanded beyond Letby’s individual convictions.

The Thirlwall Inquiry has been examining what happened at the Countess of Chester Hospital, including how concerns about unusual deaths and collapses among babies were handled by hospital management.

The inquiry has now completed its evidence and submissions phase. Its final report is expected after the summer parliamentary recess, according to the inquiry’s latest update.

That means another major development could still emerge from the wider investigation into the hospital.

 NO NEW CRIMINAL CHARGES

There was also a significant development earlier this year.

After reviewing evidence relating to nine additional babies, the Crown Prosecution Service decided not to bring further charges against Letby.

Families connected to six of those babies subsequently challenged that decision through the Victims’ Right to Review process.

On August 5, 2026, the CPS confirmed that an independent prosecutor had reviewed the decision and upheld the conclusion that the evidential test for additional charges had not been met.

That decision does not overturn Letby’s existing convictions. It concerns separate allegations that were investigated after her original trial.

 WHY THE CASE REMAINS SO CONTROVERSIAL

The continuing debate centers largely on the medical evidence.

Prosecutors at trial argued that babies were deliberately harmed through methods including the administration of air, insulin or excessive milk.

Letby’s defense has subsequently presented experts who dispute aspects of the medical interpretation and argue that some of the babies’ collapses could have had natural or clinical explanations.

Meanwhile, reporting in 2026 has also raised questions about evidence and expert testimony used during the original proceedings. For example, The Guardian reported that a key prosecution expert had been subject to a professional investigation during the period of the trial — an issue that jurors were not told about at the time.

Those developments have added another layer to the continuing legal debate.

BUT ONE THING HAS NOT CHANGED

Despite the renewed scrutiny, Lucy Letby’s convictions remain in force.

She has not been acquitted.

No court has ruled that she was wrongly convicted.

And the CCRC has not announced that her case will be sent back to the Court of Appeal.

The commission itself has warned that the case involves an exceptionally large and complicated body of evidence and that its review could take time.

THREE YEARS LATER, THE STORY IS STILL UNFINISHED

The Lucy Letby case has now entered an unusual phase.

She remains imprisoned under whole-life sentences.

Her convictions remain legally valid.

The CPS has declined to pursue additional charges.

The hospital inquiry is awaiting its final report.

And behind the scenes, the CCRC continues examining the new material submitted by her defense.

For the families who lost their babies, the continuing debate is deeply painful.

For Letby’s supporters, it represents an opportunity to have disputed evidence examined again.

And for the British justice system, the case raises a question that could have consequences far beyond one defendant:

WHEN NEW MEDICAL EVIDENCE CHALLENGES A CONVICTION, HOW FAR SHOULD THE COURTS GO TO REEXAMINE WHAT HAPPENED?

For now, there is no final answer.

Lucy Letby remains in prison — but the legal questions surrounding her case are still very much alive.
