A person who may become a cooperating witness

1) that this is opportune in view of the nature and circumstances of the criminal offense for which he is suspected of having committed;

organization shall be greater than the damaging effects of the criminal offense which he is suspected of committing;
3) that in view of the existing facts, there is reason to believe that the determination of important facts in criminal proceedings would be impossible or very difficult if the cooperating witness were not examined.
(3) Under the condition referred to in paragraph 1 of the present Article a person against whom an order of inquiry has been adopted or a direct indictment has been issued for a criminal offense against the Constitutional order and security of the Republic of Serbia and SCG, or a criminal offense against humanity and other goods protected by international law, which has been committed by three or more persons who have organized to commit criminal offenses, may become a cooperating witness.
