Oscar Pistorius will be back in the North Gauteng High Court in Pretoria on Monday, after completing his mental observation at Weskoppies Psychiatric Hospital.

The athlete was evaluated by four specialists as a day-patient.

On May 20, the court ruled that Pistorius's evaluation would inquire if he was “at the time of the commission of the offence criminally responsible” and if he could appreciate the “wrongfulness of his actions and act according to that appreciation”.

Judge Thokozile Masipa said three psychiatrists and one clinical psychologist would evaluate Pistorius to determine whether his general anxiety disorder and his disability had an effect on him when he shot his girlfriend, Reeva Steenkamp, on Valentine's Day last year.

His attorney, Brian Webber, said on Friday they were ready to go back to court on Monday.

“I anticipate that we are going to complete our evidence (when the trial resumes) so it will probably last for a couple of weeks,” Webber told Sapa.

Pistorius is charged with the murder of Steenkamp. He shot her through the locked door of his toilet in his Pretoria home. He has denied murder, saying he thought she was an intruder about to open the door and attack him.

The State contends he shot her during an argument.

He is also charged with three contraventions of the Firearms Control Act - one of illegal possession of ammunition and two of discharging a firearm in public. He has pleaded not guilty to these charges as well. - Sapa
