A/HRC/43/64 related data (A/74/277); the report of the Special Rapporteur on the rights to freedom of peaceful assembly and of association, which looked at the opportunities and challenges facing the rights to freedom of peaceful assembly and of association in the digital age (A/HRC/41/41); and the report of the Special Rapporteur on extreme poverty and human rights, which addressed the impact of the use of digital technologies in social protection systems on the enjoyment of human rights (A/74/493). G. Contributions to standard-setting, and human rights protection and promotion 24. The following mandate holders have, among other things, contributed to clarifying human rights norms and standards in relation to their mandates: (a) The Independent Expert on the effects of foreign debt and other related international financial obligations of States on the full enjoyment of all human rights, particularly economic, social and cultural rights, presented guiding principles on the human rights impact assessments of economic reforms; (b) The Special Rapporteur on the independence of judges and lawyers presented basic principles on the independence of the judiciary; (c) The Special Rapporteur on the right to development presented guidelines and recommendations on the practical implementation of the right to development; (d) The Special Rapporteur on minority issues presented a study on the concept of a minority in the United Nations system; (e) The Special Rapporteur on the implications for human rights of the environmentally sound management and disposal of hazardous substances and wastes presented principles on human rights and the protection of workers from exposure to toxic substances; (f) The Special Rapporteur on the negative impact of unilateral coercive measures on the enjoyment of human rights presented elements for a draft United Nations declaration on the negative impact of unilateral coercive measures on the enjoyment of human rights; (g) The Special Rapporteur on the human rights of internally displaced persons presented a report on the global and national activities undertaken to mark the twentieth anniversary of the Guiding Principles on Internal Displacement. 25. Special procedure mandate holders regularly address thematic issues of common interest through individual or joint actions. In 2019, these issues included, for example, new technologies, the Sustainable Development Goals, migration and climate change. A new web page reflecting the cross-cutting thematic engagement of special procedures was created. 3 It provides access to all the reports authored by mandate holders on climate change, migration, new technologies and the Goals (disaggregated by Goal). The objective is to continue to populate that web page with other cross-cutting thematic issues. H. Forums, consultations, workshops and other meetings 26. In 2019, mandate holders organized or attended more than 100 forums, consultations, expert meetings, workshops and events in all regions, in collaboration and/or engaging with Governments, the United Nations system, civil society and the private sector (A/HRC/43/64/Add.1, chap. XIX). 27. The Forum on Minority Issues held its twelfth session on 28 and 29 November 2019 in Geneva, under the guidance of the Special Rapporteur on minority issues, with a particular focus on education, language and the human rights of minorities. The Forum attracted more than 500 participants. The report was presented to the Human Rights Council at its forty-third session (A/HRC/43/62). 3 6 See www.ohchr.org/EN/HRBodies/SP/Pages/CrosscuttingThematicIssues.aspx.
