CCPR/C/70/D/547/1993 Page 15 margin of appreciation, but by reference to the obligations it has undertaken in article 27. Article 27 requires that a member of a minority shall not be denied his right to enjoy his own culture. Thus, measures whose impact amount to a denial of the right will not be compatible with the obligations under article 27. However, measures that have a certain limited impact on the way of life of persons belonging to a minority will not necessarily amount to a denial of the right under article 27.” 15 9.5 The Committee recalls its general comment on article 27, according to which, especially in the case of indigenous peoples, the enjoyment of the right to one’s own culture may require positive legal measures of protection by a State party and measures to ensure the effective participation of members of minority communities in decisions which affect them. 16 In its case law under the Optional Protocol, the Committee has emphasised that the acceptability of measures that affect or interfere with the culturally significant economic activities of a minority depends on whether the members of the minority in question have had the opportunity to participate in the decision-making process in relation to these measures and whether they will continue to benefit from their traditional economy. 17 The Committee acknowledges that the Treaty of Waitangi (Fisheries Settlement) Act 1992 and its mechanisms limit the rights of the authors to enjoy their own culture. 9.6 The Committee notes that the State party undertook a complicated process of consultation in order to secure broad Maori support to a nation-wide settlement and regulation of fishing activities. Maori communities and national Maori organizations were consulted and their proposals did affect the design of the arrangement. The Settlement was enacted only following the Maori representatives’ report that substantial Maori support for the Settlement existed. For many Maori, the Act was an acceptable settlement of their claims. The Committee has noted the authors’ claims that they and the majority of members of their tribes did not agree with the Settlement and that they claim that their rights as members of the Maori minority have been overridden. In such circumstances, where the right of individuals to enjoy their own culture is in conflict with the exercise of parallel rights by other members of the minority group, or of the minority as a whole, the Committee may consider whether the limitation in issue is in the interests of all members of the minority and whether there is reasonable and objective justification for its application to the individuals who claim to be adversely affected. 18 9.7 As to the effects of the agreement, the Committee notes that before the negotiations which led to the Settlement the Courts had ruled earlier that the Quota Management System was in possible infringement of Maori rights because in practice Maori had no part in it and were thus deprived of their fisheries. With the Settlement, Maori were given access to a great percentage of quota, and thus effective possession of fisheries was returned to them. In regard to commercial fisheries, the effect of the Settlement was that Maori authority and traditional methods of control as recognised in the Treaty were replaced by a new control structure, in an entity in which Maori 15 Committee’s Views on case No. 511/1992, Lansmann et al. v.
