In the present report, submitted pursuant to Human Rights Council resolution 42/12, the Independent Expert on the enjoyment of all human rights by older persons, Claudia Mahler, provides an overview of her activities during the reporting period and a thematic analysis of the situation of older persons deprived of their liberty in different contexts. The report examines what deprivation of liberty means from the perspective of older persons and how it affects the full enjoyment of their human rights; analyses some of the underlying causes of deprivation of liberty of older persons; highlights the human rights challenges and risks in three specific contexts (criminal justice; immigration-related detention; and care settings); and suggests ways to protect the human rights of older persons deprived of their liberty. The report concludes with a set of recommendations to States and other stakeholders.
