The law in South Africa is Roman Dutch, very different from the justice system here in the UK.
There is no jury system only a judge who hears the evidence and hands down the verdict and sentence. In this case this was revised by the Supreme Court of Appeal who has now found Pistorius guilty of murder and ordered that the trial court, which had wrongly convicted him of the lesser charge of culpable homicide, set an appropriate sentence.
The appeal court, in a unanimous judgment, found that the Pretoria High Court had erred in its application of the legal principle of dolus eventualis, and that Pistorius had clearly foreseen that he could kill somebody when he fired four shots into a locked toilet door in 2013, fatally injuring his girlfriend Reeva.
Justice has finally been done and he will serve an appropriate sentence in jail, not under house arrest in his uncle's luxury home in Pretoria!
