(3) Nothing contained in or done under the authority of any law shall be held to be inconsistent with or in contravention of this section to the extent that the law in question makes provision (a) for the imposition of restrictions on the movement or residence within Mauritius of any person in the interests of defence, public safety, public order, public morality or public health; (b) for the imposition of restrictions on the right of any person to leave Mauritius in the interests of defence, public safety, public order, public morality or, public health or of securing compliance with any international obligation of the Government, particulars of which have been laid before the Assembly; (c) for the imposition of restrictions, by order of a court, on the movement or residence within Mauritius of any person either in consequence of his having been found guilty of a criminal offence under the law of Mauritius or for the purpose of ensuring that he appears before a court at a later date for trial in respect of such a criminal offence or for proceedings preliminary to trial or for proceedings relating to his extradition or other lawful removal from Mauritius; (d) for the imposition of restrictions on the movement or residence within Mauritius of any person who is not a citizen of Mauritius or the exclusion or expulsion from Mauritius of any such person; (e) for the imposition of restrictions on the acquisition or use by any person of land or other property in Mauritius; (f) for the removal of a person from Mauritius to be tried outside Mauritius for a criminal offence or to undergo imprisonment outside Mauritius in execution of the sentence of a court in respect of a criminal offence of which he has been convicted; or (g) for the imposition of restrictions on the right of any person to leave Mauritius in order to secure the fulfilment of any obligations imposed upon that person by law, except so far as that provision or, as the case may be, the thing done under its authority is shown not to be reasonably justifiable in a democratic society. (4) Where any person whose freedom of movement has been restricted in pursuance of subsection (3)(a) or (b) so requests (a) he shall, as soon as is reasonably practicable and in any case not more than 7 days after the making of the request, be furnished with a statement in writing in a language that he understands, specifying the grounds for the imposition of the restriction; (b) not more than 14 days after the making of the request, and thereafter during the continuance of the restriction at intervals of not more than 6 months, his case shall be reviewed by an independent and impartial tribunal consisting
