These prohibitions are most clearly laid out in the Nelson
Mandela Rules, a 2015 revision and renaming of the Standard
Minimum Rules for the Treatment of Prisoners. These Rules
were approved by a United Nations General Assembly Resolution, GA Resolution 70/175.
 The applicant points to other statements such as the
Istanbul Statement adopted by a panel of experts at the International Psychological Trauma Symposium in Istanbul in 2007.
 In 2013, the Inter-American Commission on Human
Rights indicated that member states “must adopt strong, concrete measures to eliminate the use of prolonged or indefinite
isolation under all circumstances”, and stresses that this practice may never constitute a legitimate instrument in the hands
of the state.

cell for more than two hours per day because the new Correctional Service of Canada policy permits a daily shower in addition to the two hours per day that segregating inmates are

 Professor Mendez, who provided evidence submitted by
the applicant and who, among his many accomplishments, was
the United Nations special rapporteur on torture until October
31, 2016, indicates in his 2011 report to the United Nations
General Assembly that solitary confinement reduces meaningful
