The examination was conducted by British lawyer Steven Kay whom the ICTY last week imposed on Milosevic as defence counsel.
At the start of today's hearing, Milosevic protested against the court's decision to impose on him Steven Kay and Gillian Higginsa, who previously acted as friends of court.
"I insist that you give me back my right to defence," Milosevic said before presiding judge Patrick Robinson cut him off.
The tribunal decided that Milosevic would be able to examine his witnesses only after defence counsel and if the tribunal allows him to do so.
Professor Avramovic told the court that during the break-up of the Yugoslav federation she was an important associate and legal advisor of the accused. She said that she was a member of the Serb delegation at talks with intellectuals from Croatia in March 1991, at Milosevic's invitation. She said she was also a member of the delegation at negotiations ahead of the break-up of Yugoslavia in Brussels, The Hague and London.
"Milosevic wanted to point out to the awful consequences of the break-up of Yugoslavia. He was obsessed with the idea that Yugoslavia must be preserved," the witness said.
She said that during his testimony before the ICTY Croatian President Stjepan Mesic mentioned her on two occasions as a person who was "drawing up borders".
She said that countries which were formed after the break-up of Yugoslavia "do not have legal but only revolutionary legitimacy" because their borders were founded on "revolutionary achievements" of AVNOJ and not on international agreements.
Asked by defence counsel Kay whether the objective of Milosevic's strategy was "Greater Serbia", the witness answered in the negative.
"This is ridiculous. Only Yugoslavia was important to Milosevic. In Serbia he was accused of brotherhood and unity," Avramov said.
