CAT/C/LBN/CO/1 41. The Committee urges the State party to: (a) Ensure that all complaints of torture and ill-treatment are promptly investigated in an impartial manner by an independent body, that there is no institutional or hierarchical relationship between that body’s investigators and suspected perpetrators of such acts, and that the suspected perpetrators are duly tried and, if found guilty, punished in a manner that is commensurate with the gravity of their acts; (b) Ensure that the authorities launch investigations whenever there are reasonable grounds to believe that an act of torture or ill-treatment has been committed; (c) Ensure that, in cases of alleged torture and ill-treatment, suspected perpetrators are suspended from duty immediately for the duration of the investigation, particularly when there is a risk that they might otherwise be in a position to repeat the alleged act, commit reprisals against the alleged victim or obstruct the investigation; (d) Compile disaggregated statistical information relevant to the monitoring of the Convention, including data on complaints, investigations, prosecutions and convictions in cases of torture and ill-treatment (see A/69/44, annex XIII, para. 38 (ff)). Internal prison complaint mechanisms 42. While taking note of the delegation’s acknowledgement that the complaint system in prisons is regulated by outdated legislation and that measures have been taken to revise it, including by designating an ad hoc office to receive complaints in Roumieh prison, the Committee regrets that the State party has not yet established an independent State body or mechanism to investigate complaints of torture and ill-treatment against law enforcement officers. It also regrets the lack of information provided by the State party on the results of the investigation into alleged abuses committed against inmates of Roumieh prison in April 2015 (arts. 2, 12-13 and 16). 43. The Committee reiterates its previous recommendation under the inquiry procedure (see A/69/44, annex XIII, para. 38 (o)) that the State party establish a fully independent complaint mechanism with the authority to investigate promptly, impartially and effectively all reported allegations of and complaints about acts of torture and ill-treatment. Witness and victim protection 44. The Committee is concerned at the absence of an effective mechanism and an independent protection agency to ensure protection of and assistance to witnesses and victims of torture and ill-treatment (arts. 2 and 13). 45. The State party should revise its legislation and practices to ensure that witnesses and victims of human rights violations, including torture, are effectively protected against any ill-treatment or intimidation as a consequence of their complaints or any evidence given. Amnesty laws 46. The Committee is concerned that Law No. 84 of 1991 and Law No. 677 of 2005 impede the investigation and punishment of past human rights violations (art. 2). 47. The State party should repeal the amnesty laws of 1991 and 2005. It should also ensure that its laws preclude any possibility of granting amnesty to any person convicted of the crime of torture or any kind of pardon that violates the Convention. Excessive use of force against demonstrators 48. The Committee is concerned about consistent reports of excessive use of force by law enforcement officers and members of the armed forces acting to disperse demonstrators protesting in Beirut in 2015 over the lack of adequate public services, a waste management 8
