As the trial nears its close, Ghedini said he wanted to call six other witnesses on his list who hadn't yet appeared, including actor George Clooney, Real Madrid's Cristiano Ronaldo and el-Mahroug's mother.
Clooney has said he was approached by Berlusconi's team to testify about the "bunga bunga" parties, but says he only visited the premier's residence once to seek aid for Darfur and declined an invitation to stay.
Ronaldo and his lawyers have reportedly denied the Portuguese forward was even in the same city as el-Mahroug, much less had any personal contact.
"Those reports are completely false. I do not know the woman that they are talking about. I have never met her and never got together with her. On December 29, 2009, I was in Madrid training with the team," Cristiano Ronaldo said in a press release last February.
The court is expected to decide Monday on the request to hear from the additional witnesses. Two more hearings were set, on Jan. 28 and Feb. 4.
