“ 9. Section 3 (3) requires that where detention is made by the delegate of the State Government, namely, the District Magistrate or the Commissioner of Police, they should report the fact to the State Government together with the grounds on which the order may have been made and such other particulars as, in their opinion, may have a bearing on the matter. A detention order made by a District Magistrate or Commissioner of Police in exercise of their delegated authority does not remain in force for more than twelve days after the making thereof, unless in the meantime the detention order is approved by the State Government. Section 8 requires the detaining authority to communicate to the detenu, grounds on which, the order is made within five days from the date of detention to enable the detenu to make representation against the order to the State Government. Section 10 requires the State Government to place before the Advisory Board the detention order and the grounds on which such order may have been made along with the representation made by the detenu as well as the report of the officers made under Section 3(3) of the Act within three weeks from the date of detention. Under Section 11 the Advisory Board is required to consider the materials placed before it and after hearing the detenu, to submit its report to the State Government within seven weeks from the date of detention of the person concerned. In a case where the Advisory Board forms opinion, that there was no sufficient cause for the detention the State Government shall revoke the detention order but if in its opinion sufficient cause was made out, the State Government may confirm the detention order and continue the detention of the person concerned for such period not exceeding the maximum period as specified in Section 13 of the Act. Section 13 provides the maximum period for which a person can be detained in pursuance of any detention order made and confirmed under the Act. According to this provision the maximum period of detention shall be twelve months from the date of detention. The State Government has, however, power to revoke detention order at any time, it may think proper.
