JUDGMENT I.P. Singh, J. - Hari Singh Thakur has filed this Habeas Corpus Writ Petition under Article 226 of the Constitution of India to challenge the validity and legality of the detention order dated 21.8.1984 passed by the District Magistrate, Saharanpur (hereinafter referred to as the 'detaining authority') under Section 3(2) of the National Security Act (Act No. 65 of 198) (hereinafter referred to as the 'Act') with a view to preventing the petitioner (hereinafter referred to as the 'detenu') from acting in any manner prejudicial to the maintenance of public order. 2. The detention order was passed on 21.8.1984. Learned counsel for the detenu has argued that there has been violation of Section 10 of the Act in as much as the representation of the detenu dated 5.9.1984 was not placed before the Advisory Board within three weeks of the detention order. 3. The counter affidavit of the detaining authority is silent on the point as to when the representation of detenu was placed before the Advisory Board. 4. In the counter affidavit of Sri Vishnu, Upper Division Assistant in confidential Section 'VI', U.P. Secretariat, Lucknow, filed on behalf of the State Government it is mentioned in paragraph 7 that the representation of the detenu along with comments of the District Magistrate, Saharanpur were sent to the Advisory Board on 11.9.1984. Evidently, this despatch was made beyond the statutory period of the three weeks from the date of detention. This is a clear violation of provision of Section 10 of the Act and renders detention invalid. 5. As a result, the writ petition is allowed. The respondents are directed not to detain Hari Singh Thakur, the petitioner (detenu) any more in pursuance of the said detention order dated 21.8.1984 passed by the District Magistrate, Saharanpur. It is made cleat that the order passed by us to day would not entitle the detenu to his physical release if he is wanted in any other case or matter or can be lawfully detained in pursuance of any other lawful order.
