(a)he or she shall, as soon as reasonably possible, and in any case not more than seven days after the start of his or her detention, be informed in detail, in a language that he or she understands, of the grounds upon which he or she is detained and furnished with a written statement, in a language that he or she understands or, if this is not reasonably practicable, in English, specifying those grounds in detail;
(b)not more than fourteen days after the start of his or her detention a notification shall be published in a public place (and as soon as possible thereafter in the Gazette) stating that he or she has been detained and setting out the provision of law by virtue of which his or her detention is authorised;
(c)not more than one month after the start of his or her detention and thereafter during the detention at intervals of not more than six months, his or her case shall be reviewed by an independent and impartial tribunal established by law and presided over by a person appointed by the Chief Justice;
(d)he or she shall be given reasonable facilities to consult a legal representative of his or her own choice (or, if he or she is unable to retain a legal representative, such person as the tribunal may approve) who shall be permitted to make representations to the tribunal appointed for the review of his or her case; and
(e)at the hearing of his or her case by the tribunal appointed for its review he or she shall be permitted to appear in person or by a legal representative of his or her own choice or, if he or she is unable to retain a legal representative, by such person as the tribunal may approve.
(2) On any review by a tribunal of the case of a detained person in pursuance of this section, the tribunal may make recommendations concerning the necessity or expediency of continuing the detention to the authority by which it was ordered but, unless it is otherwise provided by law, that authority shall not be obliged to act in accordance with any such recommendations.
(3) Nothing in subsection (1)(d) or subsection (1)(e) shall be construed as entitling a person to legal representation at the public expense, except when the interests of justice so require.
