On 30th August, 1968, he filed a petition in the High Court of Assam under Art. 226 of the Consfaution for issue of a writ of habeas corpus. The same day he was released by the Government and, according to him, without being set at liberty, he was again put in detention in pursuance of a fresh order dated 29th August, 1968 passed under s. 3(1)(a)(ii) of the Acc. The grounds of detention were also served on the same day. He made his representation on 17th September, 1968 and his case was referred to the Advisory Board also on the same date. The report of the Advisory Board was received on 28th October, 1968. On 7th November, 1968, his order of detention was confirmed by rhe Government on the basis of the report of the Advisory Board.
