(2) Any commander or superior officer who orders, permits, acquiesces or participates in the commission of any of the crimes specified in section 3 or is connected with any plans and activities involving the commission of such crimes or who fails or omits to discharge his duty to maintain discipline, or to control or supervise the actions of the persons under his command or his subordinates, whereby such persons or subordinates or any of them commit any such crimes, or who fails to take necessary measures to prevent the commission of such crimes, is guilty of such crimes.

(b) With respect to superior and subordinate relationships not described in paragraph (a), a superior shall be criminally responsible for crimes within the jurisdiction of the Court committed by subordinates under his or her effective authority and control, as a result of his or her failure to exercise control properly over such subordinates, where:
(i) The superior either knew, or consciously disregarded information which clearly indicated, that the subordinates were committing or about to commit such crimes;
(ii) The crimes concerned activities that were within the effective responsibility and control of the superior; and
(iii) The superior failed to take all necessary and reasonable measures within his or her power to prevent or repress their commission or to submit the matter to the competent authorities for investigation and prosecution.
