Prolific paedophile Matthew Falder wins seven-year cut in jail sentence
Cambridge graduate Matthew Falder had his custodial term reduced to 25 years by Court of Appeal judges in London on Tuesday.
Bespectacled Falder watched the proceedings via video link from prison.
His barrister Andrew Smith QC told the court during the hearing: "This was grave offending with undoubtedly profound consequences for those who were the victims of this applicant."
But he submitted that "the custodial element of 32 years imposed was manifestly excessive".
The decision to allow the sentence challenge was announced by Lord Justice Holroyde, sitting with Mr Justice King and the Recorder of Winchester Judge Keith Cutler.
He said the court had concluded that the "appropriate" custodial term, taking into account credit for the guilty pleas, and "the principle of totality", was 25 years.
The sentencing judge at Birmingham Crown Court in February concluded that Falder was a dangerous offender and gave him a six-year extended licence period. This was increased to eight years by the appeal judges.
Falder, of Harborne Park Road, Birmingham, committed his offences over nearly 10 years, manipulating victims "behind a computer screen" by duping them into providing nude images and personal details.
He admitted 137 offences, including voyeurism, encouraging child rape, and sharing images showing the abuse of a newborn baby, after being caught by an international inquiry led by the National Crime Agency (NCA).
The 29-year-old was arrested in June last year after traumatised victims, who were tricked into sending him humiliating images, threatened or attempted to end their own lives.
Sentencing "warped and sadistic" Falder in February for "a tale of ever-increasing depravity", Judge Philip Parker QC said: "As for your equally extraordinary sexual offending - no-one who knew you, above ground, had an inkling of what you were doing below the surface."
Branding him an "internet highwayman" who targeted 46 victims, he added: "You wanted to assume total control over your victims.
"Your behaviour was cunning, persistent, manipulative and cruel."
Of the victims, he said: "The damage is ongoing. For these individuals it will never end, knowing the abuse caused by you still exists in other unknown persons' computers."
The unprecedented operation to catch Falder, who used specialist software to hide his online accounts, was aided by GCHQ, the US Homeland Security Department and law enforcement bodies in Israel and Australia.
On his arrest, the former post-doctoral researcher and lecturer in geophysics at the University of Birmingham quipped to officers that the list of then suspected offences sounded "like the rap sheet from hell".
Birmingham Crown Court heard that Falder coerced male and female victims into producing "increasingly severe self-generated indecent images of themselves, the focus of these images being to humiliate and degrade".
Opening the facts of the case against Falder, prosecutor Ruona Iguyovwe told the court many images were distributed on so-called "hurtcore" websites on the dark web, showing material depicting sexual and physical abuse.
Lord Justice Holroyde said the court accepted the submission made on Falder's behalf that the sentencing judge "fell into error in failing to have sufficient regard to totality" .
The prosecution submitted that although the sentence was "severe", it was not manifestly excessive having regard to the gravity of the offending.
Describing it as a "difficult case", Lord Justice Holroyde said the court had "considered carefully what total sentence would impose a just and proper punishment for the grave offences committed by this applicant".
He said of Falder: "He is now approaching his 30th birthday. He has no previous convictions recorded against him. He grew up in what was a clearly loving and caring family who are now bewildered by his offending."
The court paid tribute to the "courage" of victims who came forward to report his crimes.
The judges concluded that the new sentence should be one of 33 years, comprising the custodial element of 25 years and the extended licence period of eight years.
