[2026] IECA 86

APPROVED JUDGMENT THE COURT OF APPEAL [2026] IECA 86 Record Number: 99/2023 Edwards J. Kennedy J. Burns J. BETWEEN/ THE PEOPLE AT THE SUIT OF THE DIRECTOR OF PUBLIC PROSECUTIONS RESPONDENT/ - AND - Christopher O’Sullivan. APPELLANT JUDGMENT of the Court delivered on the 21st day of April 2026 by Ms. Justice Isobel Kennedy.

1. This is an appeal against sentence. On the 31st of March 2023, the appellant was sentenced to life imprisonment in respect of 1 count of manslaughter contrary to common law, and 1 count of arson contrary to s.2 of the Criminal Damage Act 1991, which was taken into consideration. Factual Background
2. The appellant was one of two people charged in respect of the killing of Timothy Hourihane. The appellant, his co-accused, James Brady and the deceased knew each other as they all resided in a tented village in County Cork. There had been tension between the parties in the lead up to the killing of Mr. Hourihane. The appellant and the deceased had been out drinking separately, and in the early hours of the 13th of October 2019, on returning to the tented area, the deceased was immediately set upon by Mr. Brady, which involved finger pointing and shoving. At this point the appellant was being held back, however the aggressive shouting turned into a vicious assault by the appellant and Mr. Brady where the deceased was kicked and stamped upon having fallen to the ground. The appellant continued in the assault after Mr. Brady had withdrawn and had to be pulled away from the deceased. The assault lasted between 3 and 5 minutes. They then set fire to the deceased’s tent and the appellant discarded a top he was wearing into the fire. They then proceeded to dispose of clothes in another fire that had been lit in the tented area.
3. Mr. Hourihane was left lying prone on the ground and severely injured. His attackers left. He suffered swelling of the brain, broken facial bones and his teeth were shattered, with one tooth later found in his stomach. The cause of death was blood inhalation with severe blunt force facial trauma and traumatic cardiac arrest complicated by brain swelling.
4. The appellant attended the garda station and informed the gardaí that he had returned to the tented area at approximately 9pm, went to sleep and was later woken up by the gardaí and asked to leave. CCTV footage obtained by gardaí subsequently disproved this account.
5. On the 16th of December 2019, Mr. O'Sullivan was arrested for the murder of Mr. Hourihane and made "no comment" at interview. His clothing was seized and forensically examined. Diluted blood staining which matched Mr. Hourihan’s DNA was found on the appellant’s sock, and another blood stain which matched Mr. Hourihane’s DNA was found on the appellant’s top.
6. The appellant and his co-accused were due to be tried together for murder. The appellant had indicated a guilty plea to manslaughter in December 2021 in advance of the scheduled trial date at the end of January
7. This plea was not acceptable to the Director at the time. As matters transpired, an important prosecution witness, who gave an account which was more exculpatory of Mr. Brady, died in the lead up to the trial. The indictment was ultimately severed, and the trial against Mr. Brady proceeded. Mr. Brady was subsequently found not guilty of murder but guilty of manslaughter by a jury and was sentenced to 13 years imprisonment with the final two years suspended.
8. On the 25th of November 2022, the appellant pleaded guilty to manslaughter. The sentencing hearing took place on the 30th of March 2023, and on the 31st of March 2023, the appellant was sentenced to life imprisonment. Personal Circumstances of the Appellant
9. The appellant was 40 years of age at the time of sentencing. He had suffered from alcohol and drug addiction for many years proceeding this offence. He has a number of children from whom he is estranged.
10. The appellant has 48 previous convictions namely: 14 for rape, one for sexual assault, one s.4 assault, three s.3 assaults, one robbery, seven burglaries, six criminal damage, one offence contrary to s.15 of the Misuse of Drugs Act, two offences contrary to s.3 of Misuse of Drugs Act, two for possession of knives and articles, one theft, four s.4 public order, two s.6 public order, one disorderly conduct, and two larceny. A 14 year sentence with two years suspended was imposed for the rape offences in February
11. That sentence is due to expire in October
12. Those offences were committed between May 2017 and May
13. This offending occurred some months thereafter.
14. In June 2007, an incident which gave rise to the appellant’s previous conviction for s.4 assault took place. A male was seriously assaulted by the appellant resulting in catastrophic injuries to the head. The appellant was sentenced to 8 years imprisonment for this attack, with two years suspended, in February
15. The sentencing judge in the present case was informed that the injuries in that attack bore many similarities to the attack leading to the death of Mr. Hourihane.
16. Regarding his two convictions for assault causing harm; the first related to events in November 2001, when the appellant punched a man in an unprovoked attack while the man was returning to a hotel around midnight with his wife. The injured man required surgery to his eye as a consequence of the attack. The second related to an incident in January 2019, when the appellant assaulted gardaí following a dispute at a house in Killarney.
17. A psychological report was furnished to the sentencing court which disclosed a most difficult and traumatic childhood.
18. Since the appellant’s incarceration, he has abstained from alcohol and illicit substances. He has enhanced prisoner status and is involved in upholstery and furniture repair, and a positive Governor’s report was adduced to the court in this regard. Sentencing Remarks
19. The sentencing judge remarked that the killing of Mr. Hourihane was “vicious” and that it was “carried out in a merciless and brutal manner”. He also remarked that the nature of this offending was “of the worst kind of killing and ranks as one of those offences that is just short of murder”.
20. In relation to the aggravating factors of this offence, the sentencing judge took into account the appellant’s previous convictions, some of which involved very serious and violent offending which resulted in lengthy prison sentences. He remarked that the appellant’s continuous violence was of an extreme nature that has not been stopped or discouraged by the imposition of lengthy sentences in the past. He also made reference to the appellant’s long history of substance abuse, and the fact that he has been estranged from his family. The sentencing judge also remarked that the appellant poses a very real threat to others in the future, and that he felt this needed to be taken into account.
21. The judge distinguished the appellant’s offending from his co-accused’s and remarked that the appellant continued with the extremely violent attack on Mr. Hourihane even after Mr. Brady desisted, and had to be pulled away from the deceased. He also noted that the appellant had a far more significant history of offending when compared with Mr. Brady.
22. In respect of mitigation, the judge took account of the appellant’s early guilty plea, the remorse expressed, and the apology made to the deceased’s family. He also made reference to the psychologist’s report which detailed the appellant’s difficulties in his early life and his issues with mental health. He further noted that the report sought to explore the reason for the appellant’s violent offending and how that might be addressed by him with professional support in the future, and that it also emphasises that the appellant was at a high risk of repeating the same pattern of violent behaviour post-release if he does not receive treatment as recommended in the report.
23. The judge stated: “It is only in rare and exceptional cases that a sentence of life imprisonment should be imposed in a case of manslaughter, especially where the mitigating factors, which I have identified, exist. However, the extent of this man's criminal offending has reached the stage at which he has committed extremely serious offences during his life and, more significantly in the recent past, and then this offence, resulting in the taking of human life.”
24. The judge went on to say: “It is clear from his own account of the offence and repeated offending, together with his deeply troubled nature and presentation, that outside the closed environment he would have considerable difficulty in maintaining himself in a alcohol, substance-free condition, which are the root of his offending, the death in this case and its devastating consequences. I have considered the case law in the area and in particular the decision the People DPP v. Mahon and the People DPP v. Egan in respect of imposing the maximum sentence of life imprisonment. And for the reasons given I will impose that sentence of life imprisonment, backdated to the 1st of December of 2021, because that is the date from which the indication was given of a guilty plea. That sentence will then be administered by the executive and be subject to the various steps which the offender can take to seek his release with the benefit of the programmes which should be made available to him at the appropriate stage and other avenues of sentence review via the Parole Board, which I simply note exists, but does provide a mechanism by which the concerns of the Court in this case can be addressed.” Submissions of the Appellant
25. The appellant contends that the judge erred in placing the offending within the category of ‘worst cases’ as identified in People (DPP) v Mahon [2019] 3 IR
26. It is said that the sentence imposed is excessive and disproportionate and that the imposition of a life sentence failed to have regard, or any proper regard, to the mitigating factors, and that the reasons for so imposing can only be that the sentence was one of preventative detention. Insofar as the mitigating factors are concerned, the appellant emphasises the guilty plea, the expression of remorse and the apology, and refers to People (DPP) v Molloy [2016] IECA
28. It is argued that there is too great a disparity in the sentence imposed on the co-accused, which is one of 13 years with 2 years suspended, given their roles and previous convictions. It is also said that the judge ought to have backdated the sentence to the date the appellant was remanded in custody in respect of the offence (21st of August 2020), rather than the date of the offer of a guilty plea (1st of December 2021).
29. Considerable emphasis was placed in oral argument on the contention that the primary reason for imposing a life sentence was on the basis of retribution and deterrence and to protect the public, thereby amounting to preventative detention. Submissions of the Respondent
30. It is submitted that there was an extremely high level of moral culpability meriting placing the offending in the ‘worst cases’ category, and that it was a severe and vicious attack. It is further submitted that the appellant’s conduct in the aftermath of the assault is particularly serious as he took measures to avoid being linked to the killing, namely in setting the deceased’s tent on fire and burning items of clothing. He lied to members of gardaí when he recounted his recollection of the night in question. Moreover, that the appellant’s history of offending behaviour had a significant bearing on the categorisation of the offence being placed in the ‘worst cases’ category.
31. It is submitted that imposing a life sentence where the appellant pleaded guilty does not amount to an error in principle. The Director refers to People (DPP) v McManus (orse Dunbar) [2011] IECCA 68 and People (DPP) v Egan [2017] IECA
32. In the instant case, the judge acknowledged the mitigating factors, but noted that the evidence was very strong and that the plea had to be viewed in that context. Moreover, that the judge recognised that it is only in rare and exceptional cases that life imprisonment is imposed in a case of manslaughter especially where mitigation is present.
33. The judge gave careful consideration to the totality issue and found that in the absence of his history of offending, a lengthy consecutive sentence with suspension could have resulted. However, he was of the view that such a sentence would not provide the necessary monitoring of the appellant.
34. It is submitted that the protection of the public was a legitimate factor to take into account on the facts of the present case. Discussion
35. Insofar as the appellant contends that the judge erred in finding that the case fell within the ‘worst case’ category, we cannot agree with that contention. The manner of the attack was very serious and does not need to be rehearsed here. The fact that the attack was of short duration does not detract from the intensity and viciousness of the attack. The absence of a weapon does not remove the case from the worst case category, stamping and kicking an individual lying prone and defenceless can amount to an effective weapon. The appellant kicked and stamped on the victim with a savagery which caused the shattering of his teeth and the aspiration of one of the teeth. His previous convictions for assaults and robbery, all incorporating violence, aggravate the offending, as does his conduct in the aftermath. The judge properly found that the nature of the offence was one of the worst kind of killing and ranked just short of murder.
36. Regarding the contention of an unjustified disparity in sentence between that imposed on the co-accused and this appellant, it is clear that the co-accused’s role was lesser than that of the appellant. The appellant continued with the assault after the co-accused had withdrawn; he had to be pulled from the deceased man. While the co-accused has a considerable number of previous convictions, they are of a lesser order and were dealt with in the District Court. On an examination of the transcript and the careful approach and reasons of the sentencing judge in considering this issue, we do not find an error in the difference in the sentence imposed.
37. The appellant contends that it is clear the judge imposed a life sentence for the purpose of preventative detention. This, it is said is clear from the following remarks, the first of which were made having referred to the appellant’s significant issues and the protection of society from his very high risk of offending:“A major issue for the Court is how that might be achieved, given the deep-rooted nature of the problem and the utter devastation and catastrophic consequences of his offending to date and the risk of future offending if it is not addressed.” [ ] “It is clear from his own account of the offence and repeated offending, together with his deeply troubled nature and presentation, that outside the closed environment he would have considerable difficulty in maintaining himself in a alcohol, substance-free condition, which are the root of his offending, the death in this case and its devastating consequences.”
38. It is trite to say that an offender is sentenced for the offences before the court and not for the designated purpose of preventing the commission of any offences into the future. Having said that, it is clear that in imposing a sentence which deprives a person of their liberty, that, naturally has the effect of preventing the commission of offences for that period and so can be said to constitute an element of preventative detention, assuming that the person does not offend whilst incarcerated. This of course operates as a measure to protect the public during the period of the sentence. The aspect of a preventative element is a natural consequence of a custodial sentence. It is clear from the authorities that a sentence should not be ‘any longer than is necessary to punish the offender for the offence’. The decision of the High Court of Australia in Veen v. R
