A/HRC/39/46 of the cases does not exonerate it from its obligations under the Declaration, including to take all measures necessary to prevent similar cases in the future. The Working Group is concerned that, notwithstanding repeated calls to address what appears to be a systemic problem relating to short-term enforced disappearances, the situation does not seem to have improved and calls for urgent action in this regard from the Government. 96. The Working Group also expresses serious concern about the shrinking space of civil society in Egypt and the chilling effect that this may have on individuals and organizations that report on alleged enforced disappearances. It highlights in this respect its serious concern at the case of Mr. Metwally, a lawyer and father of someone who has disappeared, who was arrested on 12 September 2017 in Egypt on his way to a meeting with the Working Group at its 113th session in Geneva (see para. 36 above). While noting the information in the lengthy response provided by the Government of Egypt to the communication sent on this case on 3 October 2017, the Working Group reiterates that the arrest and charges against Mr. Metwally point to an act of reprisal for his cooperation with a United Nations human rights mechanism, and a deliberate obstruction of his legitimate human rights activity to seek to establish the fate and whereabouts of his son and other disappeared people in Egypt. The Working Group also emphasizes that, as provided for in article 13 of the Declaration, those involved in the investigation of enforced disappearance should be protected against ill-treatment, intimidation or reprisal. It has requested an update on his case and the outstanding questions raised in the aforementioned communication and hopes to receive this information soon. 97. On 30 June 2011, the Working Group requested an invitation to visit the country. No response has yet been received from the Government in spite of reminders sent on 8 November 2012, 18 September 2013, 27 October 2014, 27 November 2015, 18 November 2016 and 19 January 2018. The Working Group hopes that a positive reply will be received soon. El Salvador 98. The Working Group welcomes two rulings from the Constitutional Chamber of the Supreme Court that ordered the Ministry of Defence and the military to conduct an internal investigation and to deliver information about military operations that involved the disappearance of children during the armed conflict (operations “guinda de mayo” and “invasión anillo”). 99. The Working Group also takes note with interest of the appointment of the commissioners of the National Commission for the Search of Disappeared Persons during the armed conflict in El Salvador (CONABÚSQUEDA) and awaits for the beginning of its activities and the creation and implementation of a national search plan. Eritrea 100. The Working Group regrets its total lack of interaction with the Government of Eritrea, including the lack of a reply to the general allegation transmitted on 21 March 2017 in relation to the alleged widespread and systematic human rights violations, including enforced disappearances, committed throughout the country over the past 25 years (see A/HRC/WGEID/111/1, para. 52 and annex II). 101. The Working Group reiterates its endorsement of the call made by the commission of inquiry on human rights in Eritrea for the Security Council to consider referring the situation in Eritrea to the International Criminal Court (see A/HRC/32/47, para. 132, and A/HRC/36/39, para. 82). Guatemala 102. The Working Group welcomes the ruling issued on 23 May 2018 by the High Risk “C” Tribunal in Guatemala against four high-ranking former military officials for crimes 20
