Parts of the SANU Memorandum are quoted word by word in the report which the witness submitted as evidence, prosecutor Geoffrey Nice warned the panel of judges during the cross-examination.
"That's possible. I wrote both the Memorandum and the report. I don't have two brains and two opinions," Mihajlovic said.
During the cross-examination, Mihajlovic denied that the memorandum was a nationalist, greater Serbian programme, claiming that the sole purpose of the document was to warn about Serbia's political and economic inequality in relation to other republics.
Asked by Milosevic to comment on claims that the Memorandum was a nationalist platform which caused the wars in the former Yugoslavia, Mihajlovic said: "On the contrary, it condemned nationalism as one of the causes of the crisis".
Asked if the document overemphasised Serbia's undeveloped economy, Mihajlovic said that there was no need to overemphasise it, because Serbia was lagging behind in all aspects as evidenced by concrete data.
"This was not a programme, but a document of warning drawn up on the basis of scientific analysis. Its purpose was to motivate the political leadership," the witness said.
Prosecutor Nice cited the late Serbian politician Ivan Stambolic as saying in October 1986 that the Memorandum was Yugoslavia's death certificate and a political insinuation which would cause "blood, darkness and evil".
The testimony of the 90-year-old witness ended the last day of the Milosevic trial for this year. The trial will continue after the Christmas and New Year holidays on January 11.
