173. Similarly, the United Nations Committee on the Elimination of Racial Discrimination indicated in its General Recommendation No. 30 that the States parties to the International Convention on the Elimination of All Forms of Racial Discrimination must: Ensure that non-citizens are not subject to collective expulsion, in particular in situations where there are insufficient guarantees that the personal circumstances of each of the persons concerned have been taken into account.239 174. In addition, the Office of the United Nations High Commissioner for Human Rights, in its report on the rights of non-citizens, underscored that: The procedure for the expulsion of a group of non-citizens must afford sufficient guarantees demonstrating that the personal circumstances of each of those non-citizens concerned has been genuinely and individually taken into account.240 175. In view of the foregoing, taking into account both the domestic norms in force in Dominican Republic and international law, it appears that a proceeding that may result in expulsion or deportation of an alien, must be individual, so as to evaluate the personal circumstances of each subject and comply with the prohibition of collective expulsions. Furthermore, this proceeding should not discriminate on grounds of nationality, color, race, sex, language, religion, political opinion, social origin or other status,241 and must observe the following minimum guarantees with regard to the alien: i) To be expressly and formally informed of the charges against him or her and of the reasons for the expulsion or deportation.242 This notification must include information about his or her rights, such as: a. The possibility of stating his or her case and contesting the charges against him or her;243 b. The possibility of requesting and receiving consular assistance,244 legal assistance245 and, if appropriate, translation or interpretation;246 ii) In case of an unfavorable decision, the alien must be entitled to have his or her case reviewed by the competent authority and appear before this authority for that purpose,247 and 239 Cf.
