Pistorius faces return to jail after appeal bid fails

Oscar Pistorius was on Thursday preparing to return to jail for 15 years after South Africa's Constitutional Court rejected his last-ditch attempt to appeal his murder conviction for shooting his girlfriend.

Pistorius's lawyers had applied for leave to appeal to the Constitutional Court, the highest court in South Africa, arguing that the Supreme Court of Appeal (SCA) had wrongly upgraded his conviction to murder.

But the National Prosecuting Authority (NPA), which opposed the application, said the appeal bid had failed.

"The court dismissed the application for leave to appeal because there are no prospects of success," NPA spokesman Luvuyo Mfaku told AFP.

Mfaku said the court's decision had been made on Wednesday.

The former Paralympic champion, 29, will attend a sentencing hearing in Pretoria on April 18.

The minimum 15-year jail term for murder may be reduced due to time he has already spent in prison.

The double-amputee killed Reeva Steenkamp, a model and law graduate, on Valentine's Day three years ago, saying he mistook her for an intruder when he shot four times through the door of his bedroom toilet.

He was released from jail in October to live under house arrest at his uncle's property in Pretoria after serving one year of his five-year prison sentence for culpable homicide -- the equivalent of manslaughter.

The SCA judges in December described his testimony at his trial in 2014 as "untruthful" and delivered a damning indictment of the original verdict.

They found him guilty of murder, overruling the culpable homicide conviction.
