JOHANNESBURG - The State says it will argue for Oscar Pistorius to receive the minimum sentence of 15 years in prison for the murder of his girlfriend Reeva Steenkamp.

The Constitutional Court yesterday rejected his application to challenge the Supreme Court of Appeal (SCA)'s decision to set aside his culpable homicide conviction.

Pistorius shot and killed Steenkamp at his Pretoria east home on Valentine's Day three years ago.

He claims he thought she was an intruder.

Pistorius has exhausted all avenues to challenge his murder conviction and will now have to fight to stay out of prison as the State pushes for the lengthy jail term.

The athlete is currently under house arrest, as was agreed in court last year after the SCA set aside his culpable homicide conviction.

NPA spokesperson Luvuyo Mfaku says the State will argue for the minimum 15 year sentence.

"On 18 April he will appear in court and the sentencing procedures will continue as planned."

June and Barry Steenkamp have welcomed the recent development, while Pistorius's brother, Carl, simply tweeted the word "shattered".
