281.Section 141 provides that if, as a result of a first review under section 139 or a further review under section 140, the responsible medical officer is not satisfied that the conditions set out in section 139(4) continue to apply or that there continues to be a need for the order, then that officer has a duty to revoke the compulsion order. The responsible medical officer must then follow the notification procedure under section 144. Revocation by the responsible medical officer does not require the approval of the Tribunal or any other person and is not subject to appeal.
