The accused was subjected to mental assessment and was found fit to stand trial and she was charged with the offence of murder and which is substituted with that of manslaughter. A Post Mortem examination report Form produced in support of the charge" 4. Mercy Chepchumba Kosgey, expresses regret and remorse for her action, saying that she attributes her offence to anger issues out of provocation from the deceased while being intoxicated. She however regrets her actions and takes full responsibility of them. 5. The Sentencing Policy Guidelines (2023) informs sentencing in Kenya to achieve proportionality, Equality, Uniformity, Parity, Consistency, Impartiality, Accountability/Transparency and Inclusiveness. 6. Sentencing is a discretion of the trial Court. In Bernard Kimani Gacheru v Republic (2002) eKLR, the Court of Appeal stated that:“ It is now settled law, following several authorities by this Court and by the High Court, that sentence is a matter that rests in the discretion of the trial Court. Similarly, sentence must depend on the facts of each case. On appeal the appellate Court will not easily interfere with sentence unless, that sentence is manifestly excessive in the circumstances of the case, or that the trial Court overlooked some material factor or took into account some wrong material, or acted on a wrong principle. Even if, the appellate Court feels that the sentence is heavy and that the appellate Court might itself not have passed that sentence, these alone are not sufficient grounds for interfering with the discretion of the trial Court on sentence unless, anyone of the matters already stated is shown to exist." 7. This Court is alive to the prime objectives of the criminal law, which is imposition of an appropriate, adequate, just and proportionate sentence commensurate with the nature and gravity of the crime and the manner in which the crime is done and that there is no straightjacket formula for sentencing an accused on proof of crime. 8. The principle of proportionality is grounded within the concept of just deserts and is embraced by common law. In Hoare v The Queen (1989) 167 CLR 348), it was stated that; “ a basic principle in sentencing law is that a sentence of imprisonment imposed by the Court should never exceed that which can be justified as appropriate or proportionate to the gravity of the crime considered in light of its objective circumstances”. 9. What sentence would meet the ends of justice? depends on the peculiar facts and circumstances of each case and the Court must keep the gravity of the crime, motive for the crime, nature of the offence and all other attendant circumstances close in mind. (See Charles Ndirangu Kibue v Republic [2016] eKLR). Further, the Court ought to bear in mind the obligation imposed on it by the Judiciary Sentencing Policy Guidelines to consider the aggravating and mitigating circumstances and their effects on the sentence in determining the most suitable sentence. https://new.kenyalaw.org/akn/ke/judgment/kehc/2026/173/eng@2026-01-19 2

The section provides for the maximum sentence, that is life imprisonment and this Court has taken into consideration the aggravating circumstances in that, the convict used a piece of timber to hit the accused in committing the offence; the facts reveal that the killing was not premeditated; the accused in a moment of uncontrolled anger having lost out in a scuffle with the deceased who had pushed the accused down and the collected the piece of timber and hit the deceased before fieeing the deceased succumbed to the injuries. 12.
