Cermak's and Markac's attorneys maintain they have enough data clearly showing that during his term in the International Criminal Tribunal for the former Yugoslavia (ICTY) Prosecutor's Office, Kehoe had worked on the Operation Storm case and could therefore not be a defence attorney in the same case.
The attorneys said they would report Kehoe by the end of the week.
They maintain that the Prosecutor's Office had the duty to inform the trial chamber presiding over the case as well as the defence teams about Kehoe's being in conflict of interest as a prerequisite for a fair trial, said Cermak's attorney Jadranka Slokovic.
The tribunal's Registry must forward conflict of interest complaints to the ICTY Bar Association for examination.
In recent statements to the press, Kehoe dismissed claims of his being in conflict of interest.
ICTY Prosecutor's Office spokeswoman Olga Kavran said that when Kehoe became a defence counsel, the Office examined the possible conflict of interest, concluding that in his case it did not exist.
The three Croatian generals are charged with war crimes committed during the 1995 Operation Storm.
