A/HRC/WG.6/1/ARG/4 page 11 41. The United States of America noted that Argentina has been bringing accused perpetrators of military dictatorship-era human rights violations to justice, and asked what plans there are to continue this effort. 42. Canada indicated that investigations are currently underway in the following cases: the killing of a prominent human rights defender and leader of a local social movement, to which the Special Representative of the Secretary-General on human rights defenders drew attention in 2004; murders of two leaders of the Pinqueteros movement in 2002; and the disappearance of Jorge Julio Lopez, a witness who had planned to appear before a court during a human rights-related trial. Canada recommended that Argentina undertake all possible efforts to protect witnesses, particularly those testifying in human rights-related trials, and further recommended that Argentina ensure that human rights defenders are protected from persecution. Canada further noted that concerns by a variety of human rights bodies were expressed regarding overcrowding and poor physical conditions prevailing in prisons, including lack of adequate hygiene, medical care and food, poor prison conditions, reports of torture and ill-treatment of children while in police custody, and that article 205 of the Code of Criminal Procedure allows for a child to be held in incommunicado detention for a period of 72 hours. Noting efforts made by Argentina, Canada recommended that Argentina continue its efforts to improve prison conditions for inmates and address issues of overcrowding and mistreatment, including of children in police custody. Finally, while encouraged by the adoption of law 24.417 on protection against domestic violence, Canada expressed concern about the prevalence of violence against women, including rape and domestic violence, as well as sexual harassment in the workplace. It recommended that Argentina continue its efforts to combat discrimination against women in all its forms and recommended that women be afforded adequate protection and redress from domestic violence and that the perpetrators of such acts be prosecuted and punished as recommended by CEDAW. 43. Chile thanked Argentina for clarifications provided on murders of Chilean citizens that have occurred in Argentina, as stated in paragraph 23 of the national report. The programmes for migratory regularization were also commended, which has benefited many Chilean citizens. Chile appreciated progress made when it comes to political participation of women, and requested more information regarding the national plan to eradicate violence against women. 44. Ukraine asked what measures are being taken aimed at combating and eradicating violence against women (including domestic violence), ensuring that women have access to protection and effective redress. Ukraine also asked about the level of cooperation between the Ministry of Justice and the Ombudsperson. Ukraine also recommended to the Government to draw particular attention to the improvement of the cooperation between the penitentiary and judicial bodies, particularly, guarantee in the legislation of the country the right to access of detainees to a lawyer immediately after detention. 45. Venezuela referred to issues raised in the national report, including economic, social and cultural rights and noted with interest the information contained in the report about the social plans and programmes developed by the Ministry of Development to improve the situation of excluded families, for example the plans for food security, families and employment. It also requested that Argentina provide more information about the measures taken under those plans and data, if any, on the impact and effectiveness of those plans. 46. The United Kingdom of Great Britain and Northern Ireland made reference to the concerns expressed by the Committee against Torture at the uneven application of the Convention against Torture in the various provinces and that the Committee on the Rights of the Child noted that there was no legislation in force at the federal level, which considered the child as a subject of rights.
