A further step was taken in 2005 by the former UN Sub-Commission on the Promotion and Protection of Human Rights which issued guidelines to assist governments to achieve and respect the human right to water and sanitation. These guidelines led the UN Human Rights Council to assign Catarina de Albuquerque as an independent expert on the issue of human rights obligations related to access to safe drinking water and sanitation in 2008. She wrote a detailed report in 2009 that outlined human rights obligations to sanitation, and the CESCR responded by stating that sanitation should be recognized by all states.
