The use of closed material procedure (“CMP”) is considers as peril to one’s right to fair hearing which ultimately raises question marks on the legality and effectiveness of the action taken. In CMP the government produces evidences to the court in absence of the party concern where the secretary of the state considers such disclosure would be a threat to the “public interest” and/or “damaging to the interests of national security”. Nevertheless, undeniably, in order to protect the operation of different secret agencies e.g. intelligence, protection of confidential information is also inevitable. Thus, this essay critically assess whether the use of CMP is well protective of the substantive human rights standards. Moreover, this essay would also evaluate whether the use of CMPs lead to compromise the procedural rights at a greater extent or whether it in fact draw a fair balance between the rule of law and national security concerns.
