Briefing the press in The Hague, he said the charges against the three evidently referred to the same case and the same facts, which was why the Prosecutor's Office would request a joinder.
The three Croat army generals are charged with violations of international humanitarian law because of crimes committed against Serb civilians and their property during Operation Storm in the wider Knin area between August 4 and November 15, 1995.
Gotovina was indicted in June 2001, and Cermak and Markac in February 2004.
"We expected this," Gotovina's US attorney Luka Misetic said regarding the joinder request.
He announced the tribunal's Registrar would this afternoon verify his appointment as Gotovina's first and that of Marin Ivanovic of Zagreb as second counsel.
Later today the two counsel are scheduled to visit Gotovina in the detention unit so that he can give them power of attorney, which they have to verify at the Registrar.
Misetic and Ivanovic visited Gotovina in the detention unit yesterday to thoroughly analyse the indictment and consider the defence.
Gotovina is charged on individual and command responsibility with seven counts of persecution, murder, deportation, forced resettlement, destruction of settlements, plunder of property, and other inhumane acts as crimes against humanity and violations of the laws and customs of war.
Gotovina was arraigned on Monday, pleading not guilty. He was arrested in Spain on December 7 and was transferred to The Hague on the 10th.
"General Gotovina is fully concentrated on his defence. He is relaxed, in a good mood, psychically strong. He received us as though we were at his house in Zagreb," said Misetic, adding Gotovina did not complain about the accommodation at Scheveningen.
He also said that after four and a half years on the run, Gotovina was now less stressed than before.
Misetic declined to comment on Gotovina's hiding, saying the lawyers' oath prevented him from commenting on that. Asked if he could confirm that he had been in touch with Gotovina in the past, Misetic said he could neither confirm nor deny this.
Misetic and Ivanovic are due in Zagreb tomorrow and are expected to meet government officials about legal, financial and other assistance to Gotovina's defence, the submission of documents related to Operation Storm, and the prosecution in Croatia of crimes during and after it.
