Killer cop Wayne Couzens will still die in prison after losing a bid to reduce his whole-life term for the kidnap, rape and murder of Sarah Everard.
It comes as the killers of Arthur Labinjo-Hughes also had their sentences reviewed by senior judges today.
In May, five judges heard challenges to or appeals against the prison sentences of five convicted killers and handed down their ruling this morning during the televised hearing.
Couzens was given a whole-life term after pleading guilty and this morning he lost his bid to reduce his sentence.
Emma Tustin was handed a minimum term of 29 years in prison after a jury found her guilty of killing six-year-old Arthur.
Two killers, Couzens and Emma Tustin, lost their bid and will continue to serve their sentences. Double-murderer Ian Stewart was the only killer to successfully reduce his sentence.
Arthur's father Thomas Hughes and Jordan Monaghan, who murdered two of his children and his partner, both had their sentences increased.
Hughes, Tustin's partner and Arthur's father, had appealed his 21-year sentence.
Stewart had appealed his whole-life order for killing his first wife six years before murdering his fiancee.
The fifth killer who appealed his sentence is Monaghan who received a minimum 40-year term for murdering two of his children and his wife.
Today, the judges gave their ruling on whether any of the sentences should be increased or lowered as they consider how whole-life orders are imposed.
Wayne Couzens - lost his appeal
Couzens, 48, was given a whole-life term after the "devastating, tragic and wholly brutal" rape and murder of Sarah, 33.
The Old Bailey heard that Couzens pretended to arrest Sarah in a fake Covid patrol and showed her his warrant card to abduct her.
During sentencing, Lord Justice Fulford said Wayne Couzens carried out "warped, selfish and brutal offending that was both sexual and homicidal".
Couzens appeared in court in May to plead not guilty to four separate charges of indecent exposure. The alleged incidents of flashing were said to have happened on four occasions in January and February 2021, while he was a police officer.
Appealing against the whole-life term, Couzens's lawyers argued he deserved "decades in jail" but said a whole-life term was excessive.
He lost his bid this morning, meaning he will still die in prison.
Lord Burnett said today: "We agree with the judge that having determined there should be a whole life order, given the misuse of Couzens' role as a police officer and the serious aggravating features of the offending the guilty pleas did not affect the outcome."
Emma Tustin - lost appeal and Thomas Hughes' sentence increased by 3 years
The 32-year-old was handed a minimum term in prison of 29 years after being found guilty of the murder of Arthur.
Hughes - who was told his “infatuation” for Tustin had “obliterated” his love for his son – was jailed for 21 years after being found guilty of manslaughter.
The court heard Arthur was left with an unsurvivable brain injury while in the sole care of "evil" Tustin.
She forced Arthur to sleep on the floor, poisoned him with salt and banged his head as part of a catalogue of abuse that disgusted the UK.
Arthur, whose body was also covered in 130 bruises, died in hospital following a horrific assault at the hands of Tustin in June 2020.
Tustin and Arthur's father, Hughes appealed against the length of their sentences which were also challenged as being unduly lenient.
Tustin lost her bid this morning while Hughes' sentence was increased to 24 years.
Ian Stewart - sentence reduced to 35 years
Ian Stewart was found guilty of murdering Diane Stewart after jurors rejected his account that he found her collapsed having suffered an epileptic fit at their home in Bassingbourn, Cambridgeshire.
Prosecutors said it is most likely Diane's death was caused by a prolonged restriction to her breathing from an outside source, such as smothering or a neck hold.
Stewart was previously jailed for killing Helen Bailey the popular writer of the Electra Brown books, whose body was found in the cesspit of their £1.5 million home in 2016.
Diane, 47, died several years earlier and the cause was believed to be epilepsy.
But following his original murder conviction, detectives opened a new investigation.
He's also appealed his whole-life order.
Amjad Malik QC, for Stewart, argued that the whole-life order he was given for the murder of his first wife was not justified in the circumstances of the case.
Stewart successfully got his sentence reduced and he will now serve a minimum term of 35 years.
Jordan Monaghan - sentence increased by 8 years
Monaghan was jailed in December 2021 for the murder of two of his children and partner.
He smothered his 24-day-old daughter Ruby as she slept in a Moses basket on New Year’s Day 2013.
Eight months later he smothered his 21-month-old son Logan, and six years after that he murdered his new partner, Evie Adams, with a drug overdose.
Judges also reviewed the potentially unduly lenient sentence of Monaghan, who was handed a minimum term of 40 years at Preston Crown Court after he murdered two of his children and his new partner.
Today, judges said his sentence was too lenient and he will now serve 48 years.
