Prosper was jailed for life with a minimum term of 49 years in March after he murdered 48-year-old Julianna Falcon, 13-year-old Giselle Prosper and 16-year-old Kyle Prosper at their family flat in Luton, Bedfordshire, on September 13 2023.
19-year-old Prosper also faced additional sentences for weapons offences, having plotted a mass shooting at his former primary school.
The Solicitor General referred Prosper’s sentence to the Court of Appeal in April, with barristers telling a hearing in London that a whole-life term was a “just punishment” for the “exceptional” crimes.
Barristers for Prosper, who is due to be released in his late 60s at the earliest, said the sentence “cannot be said to be unduly lenient”.
In a ruling, the Lady Chief Justice Baroness Carr, sitting with Mr Justice Goss and Mr Justice Wall, said that Prosper’s sentence was “itself a very severe sentence for a 19-year-old”.
She said: “These were undoubtedly offences of the utmost gravity, with multiple features incorporating disturbing, recurrent themes around school shootings.”
She continued: “Had the offender been 21 or over at the time of the offending, a whole-life order would undoubtedly have been made.”
She added that the sentencing judge, Mrs Justice Cheema-Grubb, was right to conclude that the “enhanced exceptionality test” of whether to pass a whole-life term on an 18-to-20-year-old was “not met on the facts”.
She said: “Parliament chose to set what is already a very high threshold for a whole-life order for an adult, even higher for a young offender.”
She concluded: “Appalling though these crimes were, we are not persuaded that anything less than a whole-life order was unduly lenient.”
Prosper watched proceedings via a video link from HMP Belmarsh.
Whole-life orders are reserved for the most serious offences, with those handed the tariffs including Louis De Zoysa, who murdered Metropolitan Police Sergeant Matt Ratana in 2020, and Kyle Clifford, who murdered his ex-partner Louise Hunt, her sister Hannah Hunt and mother Carol Hunt last year.
