Oscar Pistorius did not have a mental disorder when he killed his girlfriend, a psychological report said as his murder trial resumed.
That meant the Olympic athlete was criminally responsible for his actions when he shot her, the prosecution said.
The defence team has said Mr Pistorius was suffering from an anxiety disorder.
The athlete denies deliberately killing Reeva Steenkamp. He says he shot her accidentally in a state of panic after mistaking her for an intruder.
The prosecution says Mr Pistorius deliberately killed Ms Steenkamp following an argument.
Both prosecution and defence have accepted the results of the psychological report but it has not been published.
“Mr Pistorius did not suffer from a mental illness or defect that would have rendered him criminally not responsible for the offence charged,” said state prosecutor Gerrie Nel, reading from the psychologist report.
