An appellate court will not normally interfere with the discretion exercised by the
trial judge in assessing sentence unless it is evident that the judge acted upon some wrong principle, or overlooked some material
factor. See James s/o Yoram v. R (1950) 18 EACA 147. It is also an accepted principle that although an appellate court can interfere with a sentence which was imposed
by a lower court, it is a power which it does not exercise lightly, and will not alter a sentence merely because, had it been the
trial court, it might have passed a different sentence ? See Ogalo s/o Owoura v. R (1954) 21 EACA 270. That is especially so in the case of a second appeal or where there was a full trial in which the trial court
had the advantage of seeing and hearing witnesses. It is said, however, that where an accused person pleaded guilty and sentencing
followed straight from it so that no evidence was adduced to give the trial court an advantage in assessing sentence, an appellate
court may be in as good a position as the trial court in assessing the appropriate sentence. See Nuttall (1908) 1 Cr. App. R. 180.
Generally, an appellate court will alter a sentence if it is evident that it is manifestly
excessive. What is implied here is that the appellate court will not interfere with a sentence assessed by a trial court merely because
it appears to be severe. It will only interfere if it is plainly excessive in the circumstances of the case.
In the case under appeal, at the time the appellant committed the offence, he was
of the age of 19 years. According to an extra-judicial statement of the appellant which was before the sentencing judge, the appellant
had cracked a joke about the deceased. Apparently, the deceased took exception to the joke and approached the appellant menacingly
so that the latter took to flight. Eventually he reached home. The following words by the appellant are quite revealing about what
transpired just before he stabbed the deceased to death ?
gNilipofika mlangoni ndipo marehemu alinyanyuka na kunifuata hapo nje na kuanza kunipiga usoni na teke la ubavuni mkono wa kushoto.
Nami nilitoka nje kukimbia lakini aliniwahi na nilirudi salon na ndipo nilishika mkasi nikwa (sic) ninamtishia ukija hapa nitakuchoma
lakini alikuja kwa kasi na kunisukumia kwenye ukuta na mkazi (sic) niliokuwa nao nilimchoma sehemu ya tumbo mkono wa kushoto ch
It was in those circumstances that the appellant killed the deceased.
We think that had the High Court judge properly considered those circumstances he
would not have found it necessary or desirable to refer to the incident as youth hooliganism which exceeded sane boundaries, when
referring to the appellant. If anyone at all had exceeded gsane boundariesh, it was the deceased, so that, as pointed
out by Mr. Banturaki, the deceased had authored his own death by so relentlessly pursuing the appellant when the latter had retreated
so much. The deceased had turned into an aggressor.
When those circumstances are considered along with the youth of the appellant at
the time he caused the death of the deceased, his sense of remorse, the fact that he readily pleaded guilty and was a first offender,
it becomes patently clear that the trial judge had failed to take into consideration material factors, justifying interference by
this Court.
It was for the above reasons that we immediately allowed the appeal and reduced the
sentence to the extent explained above.
