JOHANNESBURG - With paralympian Oscar Pistorius's sentencing proceedings being just weeks away, questions are being asked about whether he'll testify in a bid to secure a lesser sentence than the prescribed 15 years in prison.

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

Pistorius shot and killed his girlfriend Reeva Steenkamp on Valentine's Day three years ago, but he claims he thought she was an intruder.

Attorney Ulrich Roux says Pistorius's legal team should put him in the witness box to testify in mitigation of sentence.

"He is very remorseful about what has happened and shows the court how this tragedy had affected his life. He should be able to withstand cross-examination. I think that would stand him in good stead."

It remains to be seen if Pistorius would want to subject himself to prosecutor Gerrie Nel's cross-examination, which had him in tears on several occasions during the trial.

Roux says the year Pistorius spent in prison and the programmes he went through will count in his favour.
