A/HRC/19/57 21. The Working Group also decided to maintain the text of its Opinion No. 32/2010 (Peru) concerning the detention of Mr. Polo Rivera. The Working Group considered that the Government has not provided it with new facts within the meaning of paragraph 21 of its methods of work so as to warrant a review of its Opinion. 22. The Working Group is examining a request for review of its Opinion No. 46/2011 (Viet Nam) submitted by the Government of Viet Nam. 23. The Working Group is also examining a request for review of its Opinions Nos. 15/2011 (China) and 16/2011 (China) submitted by the Government of the People’s Republic of China. 5. Communications giving rise to urgent appeals 24. During the period 18 November 2010–17 November 2011, the Working Group transmitted 108 urgent appeals to 45 Governments concerning 1,629 persons (1,526 men, 99 women and four minors). In conformity with paragraphs 22–24 of its revised methods of work (A/HRC/16/47, annex), the Working Group, without prejudging whether the 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’ right to life and to physical integrity were respected. 25. When the appeal made 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 relating to urgent appeals and has since applied them. 26. During the period under review, 108 urgent appeals were transmitted by the Working Group as follows: Table 2 Urgent appeals transmitted to Governments by the Working Group 12 Government concerned Number of urgent appeals Persons concerned Afghanistan 1 2 men Armenia 1 80 men Bahrain 5 20 men, 6 women, 1 minor Bangladesh 1 1 man, 1 woman Belarus 3 8 men, 4 women Cambodia 1 1 man China 12 423 men, 29 women Côte d’Ivoire 1 1 man Cyprus 1 3 men Persons released/Information received from Released: 3 (source) Released: 1 (Government)
