A/HRC/27/48 4. Requests for review of opinions adopted 25. The Working Group considered the concerned Governments’ requests for review of the following opinions: opinion No. 46/2012 (Guatemala), opinion No. 62/2012 (Ethiopia) and opinion No. 37/2012 (Spain).

Reprisal against a subject of an opinion of the Working Group 26. The Working Group expresses its concern regarding the continued detention under house arrest of Marìa Lourdes Afiuni Mora, the subject of its opinion No. 20/2010 (Bolivarian Republic of Venezuela), who was arrested in 2009 for ordering the conditional release of Eligio Cedeño, the subject of the Working Group’s opinion No. 10/2009 (Bolivarian Republic of Venezuela).

In conformity with paragraphs 22 to 24 of its methods of work (A/HRC/16/47, annex, and Corr.1), the Working Group, without prejudging whether a detention was arbitrary, drew the attention of each of the Governments concerned to the specific case as reported, and appealed to them to take the necessary measures to ensure that the detained persons’ rights to life and to physical integrity were respected. 29. When the appeal made a reference to the critical state of health of certain persons or to particular circumstances, such as failure to execute a court order for release, the Working Group requested the Government concerned to take all necessary measures to have the person concerned released. In accordance with Human Rights Council resolution 5/2, the Working Group integrated into its methods of work the prescriptions of the Code of Conduct for Special Procedures Mandate-holders of the Human Rights Council relating to urgent appeals and has since applied them. 30. During the period under review, the Working Group also sent two letters of allegation to Nigeria and Sudan, pursuant to the Code of Conduct for Special Procedures Mandate-holders of the Human Rights Council. 1 14 For urgent appeals sent from 1 December 2012 to 28 February 2014, see A/HRC/23/51, A/HRC/24/21, A/HRC/25/74, A/HRC/26/21.
