ayne couzens and Arthur Labinjo-Hughes’s killers must find out in the Court of Appeals whether their prison terms have been changed.
In May, five judges heard objections or appeals to the prison terms of five convicted murderers, including the life sentences of former police officer Couzens and double murderer Ian Stewart.
Emma Tustin and Thomas Hughes, who killed Arthur, were also reviewed, along with triple murderer Jordan Monaghan.
On Friday, the judges will rule on whether to increase or decrease any of the sentences as they consider how life sentences will be issued.
Last year, Couzens was sentenced to life in prison for the rape and murder of a 33-year-old Sarah Everardthe first time the sentence had been imposed for a single murder of an adult not committed during a terrorist attack.
Couzens’ lawyers appealed the life sentence, claiming he deserved “decades of years in prison,” but said a life sentence was excessive.
In reviewing the sentences of the six-year-old Arthur’s killers, the Court of Appeal was told that he suffered an insurmountable brain injury while in the care of Tustin, who was sentenced to life imprisonment with a minimum term of 29 years.
Tustin and Arthur’s father, Hughes, who was sentenced to 21 years for manslaughter, appealed the length of their sentences, which were also challenged as being overly lenient.
Double murderer Stewart, who killed his wife for six years before going on to kill his fiancée, also appealed his life sentence.
Stewart murdered 51-year-old children’s author Helen Bailey in 2016 and was found guilty of murdering her in 2017.
Following this conviction, police investigated the death of Stewart’s first wife, Diane Stewart, 47, in 2010, and in February he was found guilty of murdering her.
Amjad Malik QC, for Stewart, argued that the life warrant he was given for the murder of his first wife was not justified in the circumstances of the case.
The judges also assessed Jordan Monaghan’s possibly too lenient sentence, who was handed a minimum sentence of 40 years. Preston Crown Court after killing two of his children and his new partner.
The verdict of the Lord Chief Justice Lord Burnett and four other judges will be delivered at 9.30am.
