A/HRC/27/55 84. The Special Rapporteur recommends that the United Nations treatymonitoring bodies and regional human rights mechanisms: (a) Request that States provide information in their periodic reports on how they address the comprehensive range of violations of the rights to water and sanitation are addressed; (b) Ensure that complaints procedures are applied so as to ensure access to justice, including both restorative and transformative remedies, for the comprehensive range of violations of the rights to water and sanitation, 85. The Special Rapporteur recommends that non-State actors comply with their responsibility to respect human rights, that they be held accountable for human rights abuses, allow for an independent investigation into allegations, establish complaint mechanisms and proactively engage with the State to detect, and find solutions to address existing and potential human rights abuses . 86. The Special Rapporteur encourages civil society organizations to support (strategic) litigation, in particular related to systemic and structural violations of the rights to water and sanitation linked to the obligations to progressively realize human rights, to use maximum available resources, to avoid unjustifiable retrogression, and to achieve substantive equality, including through preventing and combating stigmatization. 25
