Pistorius's appeal decision due on Thursday

South Africa's Supreme Court of Appeal said on Tuesday it will announce on December 3 if it will overturn Oscar Pistorius's conviction of manslaughter for killing his girlfriend Reeva Steenkamp, a decision that could send the track star back to jail.

The Paralympic gold medallist was freed on parole last month after serving a fifth of his prison term for the 'culpable homicide' of Steenkamp, who he killed on Valentine's Day 2013.

Prosecutors said Pistorius should be convicted of murder and sent back to jail, while the defence argued that the sentence the athlete had received was appropriate and should stand.
