Oscar Pistorius is set to appear in court Tuesday for a bail hearing that could see him return to jail after he was convicted on appeal of his girlfriend's murder, officials said.

The South African Supreme Court of Appeal last week overturned his earlier conviction on the lesser charge of culpable homicide for shooting dead Reeva Steenkamp in the early hours of Valentine's Day, 2013.

Pistorius, 29, is currently under house arrest in Pretoria after serving one year of his five-year prison sentence for culpable homicide -- the equivalent of manslaughter.

"It's a bail application. His (earlier) conviction has been overturned, so his sentence from before has been scrapped," Lusanda Ntuli, spokeswoman for the justice ministry, told AFP on Monday.

"The defence and prosecution will present their arguments."

The double-amputee Paralympian sprinter, known as the "Blade Runner" because of the prosthetic legs he uses on the track, now faces a minimum 15-year jail sentence for murder, although the term could be shorter if he is released on parole.

No date has yet been announced for his sentencing.

"If he is given bail, it may come with different conditions perhaps not as stringent as house arrest," criminal lawyer Martin Hood told AFP.

Pistorius killed Steenkamp, a model and law graduate, at his home in Pretoria two years ago, saying he mistook her for an intruder when he shot four times through the locked door of his bedroom toilet.

The appeal court changed his conviction to murder and sent the case for re-sentencing, saying the original trial judge had made "fundamental" errors in her ruling last year.

The appeal decision, read by judge Eric Leach, said that it was "inconceivable that a rational person could have believed he was entitled to fire at this person with a heavy calibre firearm".

Last month, Pistorius made his first appearance in public since leaving jail in October when he reported for community service at a Pretoria police station.

Pistorius, 29, killed Steenkamp at the peak of his fame, and he has since lost his glittering sports career, lucrative contracts and status as a global role model for the disabled.

He may make his own appeal to the Constitutional Court -- the country's highest court, but his lawyers have said the sprinter cannot afford further legal battles after paying huge bills.

"I wanted respect for my daughter's life, and that's what I got," Reeva's mother June Steenkamp, who was in court, said shortly after the unanimous ruling by five appeal judges.
