The Court of Appeal has quashed an unlawful sentence of imprisonment for public protection imposed on Niki Dean Haycock in 2006. In its judgment handed down on 21 August 2026, the court described the appeal as unanswerable and warned of a wider gap in the system for people serving IPP or DPP sentences who have never appealed.
The ruling does not minimise the seriousness of the underlying offending. Its legal significance is that the sentencing court lacked power to impose an IPP sentence for the offences of conviction. It also shows how an unlawful sentence can remain undetected when no appeal or eligible Criminal Cases Review Commission referral brings it before a court.
Why was the original IPP sentence unlawful?
Mr Haycock pleaded guilty in 2006 to controlling prostitution for gain and two offences of assault occasioning actual bodily harm. The Crown Court imposed an IPP sentence with a minimum term of 30 months.
Under the law then in force, an IPP could be imposed only for a qualifying “serious offence”. The Court of Appeal found that none of the three offences met that definition: the controlling-prostitution offence carried a maximum sentence of seven years, while each assault offence carried a maximum of five years.
The court therefore concluded that the Crown Court had no legal power to impose an IPP sentence. The error was identified in April 2026 when a solicitor preparing for Mr Haycock’s Parole Board review examined the original sentencing basis.
What sentence did the Court of Appeal substitute?
The court allowed an extension of time of 7,291 days and granted leave to appeal. It quashed the IPP on the principal count and substituted an extended sentence of seven years, comprising a five-year custodial term and a two-year extension period.
Because Mr Haycock had already served far longer than that sentence, the order released him from the sentence and from the associated licence. The judgment records that, apart from a short period on licence, he had been imprisoned for almost three times the maximum determinate sentence available for the relevant offence.
Why did the court identify a wider systemic problem?
IPP and DPP sentences were abolished for offenders convicted on or after 3 December 2012, but the abolition was not retrospective. The judgment records official figures showing 856 unreleased and 1,415 recalled IPP prisoners in England and Wales on 30 June 2026.
The Court of Appeal explained that it can examine a sentence when an appeal reaches it, while the Criminal Cases Review Commission can consider cases within its statutory remit. Neither route, however, automatically identifies people still subject to an IPP or DPP sentence who have never appealed.
The court called for a system to identify those cases and ensure the people affected know that legal advice may be available. It also cautioned that not every IPP or DPP sentence will be unlawful and that review should not create false expectations.
What should practitioners watch next?
The immediate question is whether the Government, prisons, legal-aid providers or another public body establishes a systematic review and advice process. Practitioners acting for people still subject to legacy IPP or DPP sentences may also need to verify the original statutory gateway rather than assuming the sentence was legally available.
Independent reporting by the Solicitors Journal highlights how the error was found during parole-review preparation. The approved judgment remains the authoritative source for the court’s reasoning and order.
