Olympic and Paralympic track star Oscar Pistorius takes notes during court proceedings at the North Gauteng High Court in Pretoria March 13, 2014.

Prosecutors in the murder trial of Paralympic champion, Oscar Pistorius, on Tuesday brought an application before the High Court in Pretoria to have the accused admitted for mental observation.

"We are mindful that if granted that it could lead to a delay," state prosecutor Gerrie Nel said.

Nel noted that forensic psychiatrist Merryll Vorster said [link id="391" tax="post_tag" text="Oscar Pistorius"] suffered from general anxiety disorder, which was listed as a mental illness. He said the disorder was serious.

"The fact that it is psychiatric analysis, it may play a role," said Nel. "[During the trial] there has been no indication of any abnormal anxiety."

On Tuesday, during cross examination by prosecutor Gerrie Nel, defence witness, forensic psychiatrist Merryll Vorster said: “People with general anxiety disorder are not dangerous as such. People with general anxiety disorder probably shouldn’t have firearms, that’s what makes them dangerous.”

“So many people in society have general anxiety disorder, but they are not threats as such. So the diagnosis as such is not one where one would associate [them] with violence.”

She said such people were often at risk of obtaining firearms because they feared for their safety. Oscar Pistorius is charged with murdering his girlfriend Reeva Steenkamp. He shot her dead through the locked door of his toilet in his Pretoria home on February 14 last year.

He has denied guilt, saying he thought she was an intruder about to open the door and attack him. The state contends he shot her during an argument. Vorster told the court she looked at the defence’s version of what happened, but said she would not be able to say which version the court would accept.

She said she did not look at the state’s version. She was given a transcript of Pistorius’s version but did not go through it because “it is not necessarily the version that the court would accept”.

Nel asked Vorster if the state’s version would affect her view or diagnosis. “No it wouldn’t have made a difference because the diagnosis stays constant. Two factors that are constant is the anxiety disorder and the vulnerability [of Pistorius],” she said.

Nel asked whether a person with general anxiety disorder would be anxious in a fight. Vorster said yes, more so than normal people. She agreed that the general anxiety disorder would have played a role.

“Because the individual would be anxious about losing a relationship. If there had been an argument about a relationship a person with general anxiety disorder would have been anxious.”

Pistorius 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. The hearing continues.
