BLOEMFONTEIN - The fate of Oscar Pistorius hinges on just a few hours of legal argument, which is expected to be heard in the Supreme Court of Appeal (SCA) in Bloemfontein today.

Pistorius is currently under house arrest at his uncle's Waterkloof mansion after being convicted of killing his girlfriend Reeva Steenkamp on Valentine's Day two years ago.

The full bench of five judges has had several months to consider the state and defence's cases, which were first submitted in writing.

Proceedings are scheduled to start at 10am and will finish today, even if that means sitting into the night.

Defence advocate Barry Roux indicated in his court papers that he will need at least five hours to argue his case.

But the judges will have the final say.

SCA judges are known to question council throughout their arguments.

Prosecutor Gerrie Nel believes Judge Thokozile Masipa made a mistake by incorrectly applying the principle of 'dolus eventualis' and that the athlete must be convicted of murder.

Roux has argued that Masipa got it right and that Nel is attempting to argue points of fact as points of law.

It's understood June Steenkamp will attend proceedings today and will be joined by the ANC Women's League.
