However, this does not apply to those who are accused of being directly responsible for crimes committed by the unit or who know the circumstances of the case and have the obligation to testify. If it is difficult to determine a litigation agent in accordance with the provisions of the preceding paragraph, the defendant unit may entrust someone from another unit other than a lawyer to serve as the litigation agent.
