Administrative detention is detention without charge or trial that is authorized by administrative order rather than by judicial decree. Under international law, it is allowed under certain circumstances. However, because of the serious injury to due-process rights inherent in this measure and the obvious danger of its abuse, international law has placed rigid restrictions on its application. According to international law, administrative detention can be used only in the most exceptional cases, as the last means available for preventing danger that cannot be thwarted by less harmful means.
Israel's use of administrative detention blatantly violates these restrictions. It is carried out under the thick cover of privilege, which denies detainees the possibility of mounting a proper defense. Over the years, Israel has administratively detained thousands of Palestinian for prolonged periods of time, without prosecuting them, without informing them of the charges against them, and without allowing them or their attorneys to study the evidence, making a mockery of the protections specified in Israeli and international law to protect the right to liberty and due process, the right of defendants to state their case, and the presumption of innocence.
As of the end of June 2012, Israel was holding about 285 Palestinians in administrative detention (for detailed figures click here).
