An Australian television network which broadcast video of Oscar Pistorius re-enacting the moment he shot his girlfriend dead has claimed it did not obtain the footage illegally.
The video, which shows Pistorius running on his stumps simulating holding a gun, was aired on Channel Seven yesterday.
It is understood Pistorius' legal team is planning to take legal action against the network.
His family said the footage, filmed to create a "forensic animation", was "obtained illegally".
The broadcasting of the video was not explicitly raised in court today, as the murder trial reconvened.
The six-time Paralympic gold medallist denies deliberately killing his girlfriend Reeva Steenkamp on February 14 last year.
He says he thought there was an intruder in his Pretoria home when he fired four shots through a toilet door.
The footage broadcast by Channel Seven also shows Pistorius re-enacting the moment he moved Steenkamp's body from the toilet.
His sister Aimee took the place of Steenkmap in the video.
The executive producer of Channel Seven's Sunday Night programme defended the airing of the footage.
"We would not have run the footage if we thought we had obtained it illegally," AFP quoted Mark Llewellyn as saying.
"The material shown on Sunday Night goes to the heart of both the prosecution and defence cases, including the account provided by Oscar Pistorius."
The court today heard more evidence from sports medicine Professor Wayne Derman, who was asked about Pistorius' mobility on his stumps.
Derman, who has treated Pistorius for six years and worked with the South African Olympic team, conceded fleeing to another room when he thought there was an intruder would have been an "option" for the athlete.
On Friday, Derman said Pistorius had an "exaggerated fight response" and suffered "significant stress and anxiety".
The defence team is expected to close its case tomorrow, before an adjournment for closing statements to be prepared.
