The judge at the Oscar Pistorius trial banned the "explicitly graphic" evidence of a pathologist who carried out an autopsy on the Olympian's slain girlfriend from being broadcast or tweeted.
Professor Gert Saayman testified Monday about the extent of injuries suffered by model Reeva Steenkamp when the double-amputee fatally shot her on Feb. 14, 2013. Pistorius says he mistook her for an intruder.
But before the expert took the stand, chief prosecutor Gerrie Nel asked the judge to bar broadcasting of his "explicitly graphic" evidence. The sprinter's lead defense lawyer Barry Roux also supported the move.
"It's not a question of press freedom," Nel said.
Saayman is the head of the forensic medicine department at the University of Pretoria.
Proceedings can be partly televised and the audio can be broadcast in its entirety under a judge's pre-trial order that sought to balance the right to a fair trial with the intense public interest in the Pistorius case and the principle of open justice. Under the order, some witnesses can choose not to be shown on television.
Judge Thokozile Masipa ruled that the testimony could not be broadcast or tweeted but could be summarized.
The trial continues.
