officers. Any such law (and the measures taken under it) will be tested against the criterion of what would be reasonably justifiable in a democratic society. X. Freedom of Assembly and Association 1. It will be forbidden, except with the consent of the person concerned, to interefere with anybody's freedom of assembly and association. This freedom will be defined as the right of every person to assemble freely and associate with others and in particular to form or belong to political parties or to trade unions or other associations for the protection of his interests. 2. There will, however, be an exception for any law (and for any measures taken under it) which makes reasonable provision in the interests of defence, public safety, public order, public morality or public health; or which makes reasonable provision to protect the rights and freedoms of others; or which imposes restrictions on public officers. Any such law (and the measures taken under it) will be tested against the criterion of what would be reasonably justifiable in a democratic society. XI. Freedom of Movement 1. It will be forbidden to interfere with anybody's freedom of movement. This freedom will be defined as the right to move freely throughout Zimbabwe, the right to reside in any part of Zimbabwe, the right to enter Zimbabwe, the right to leave Zimbabwe and immunity from expulsion from Zimbabwe. 2. There will, however, be an exception for any law (and for any measures taken under it) a. which imposes reasonable restrictions on the movement within Zimbabwe of persons generally or any class of persons, or on their right to leave Zimbabwe, in the interests of defence, public safety, public order, public morality or public health; b. which imposes reasonable restrictions on the acquisition or use of land; c. which authorises a court to impose restrictions on any person's movement or residence within Zimbabwe or on his right to leave Zimbabwe, in consequence of his criminal conviction or to ensure his appearance before a court to stand trial for a criminal offence or to give evidence in criminal proceedings or to answer extradition or deportation proceedings; d. which imposes restrictions on the freedom of movement of anybody who is not a citizen of nor permanently resident in Zimbabwe; e. which authorises the extradition of a person from Zimbabwe in respect of a criminal offence or his removal to some other country to serve his sentence for such an offence; f. which imposes restrictions, in order to secure the fulfilment of any person's legal obligations, on his right to leave Zimbabwe; or g. which imposes, for the protection of tribespeople, restrictions on residence within Tribal Trust Land for those who are not tribespeople. In all these cases, save the restrictions relating to Tribal Trust Land, any such law (and any measures taken under it) will be tested against the criterion of what would be reasonably justifiable in a democratic society. XII. Protection from Discrimination 1. It will be forbidden for any law to contain a provision which is discriminatory either of itself or in its effect or for any person who is exercising statutory powers or acting in the performance of the functions of any public office or public authority to treat anybody in a discriminatory manner. A law or an executive action of this kind will be regarded as discriminatory if it affords special advantages or imposes special disabilities upon persons by reason wholly or mainly of their race, tribe, place of origin, political opinions, colour or creed.
