A/HRC/8/30 Page 13 children in Poland. While noting the measures taken by Poland to address the continuing occurrence of violence against children, Sweden asked what measures it is taking to ensure the sufficient legal protection of the freedom of children from physical or mental violence. 40. Cameroon noted with great interests the measures taken and provisions made by Poland with a view to diligently implement the judgements of the European Court of Human Rights which demonstrates the effectiveness of these rights for all people living in Poland. Cameroon joined the recommendations made by a number of treaty bodies, and encouraged Poland to intensify its efforts to fight against all forms of discrimination and to promote and protect dignity and equality which are the guiding principles of concrete and effective implementation of human rights. 41. Mexico acknowledged the efforts made by Poland in the area of human rights, specifically to fight racism and discrimination, to improve conditions of detention, to provide assistance to victims of crimes such as trafficking of persons, to improve human rights in a number of different public offices and its programmes to combat domestic violence and unemployment. Mexico welcomed the Polish open invitation to all special procedure mandate holders. In view of these achievements, Mexico invited Poland, to the extent possible, to ensure that practical policies in the area of immigration be geared to the standards set forth by the principles enshrined in the ICRMW, and recommended that Poland ratify the Convention. While noting Polish efforts to strengthen the judiciary, Mexico encouraged Poland to make legal amendments that will make it possible to effectively prosecute offences related to torture and other cruel, inhuman or degrading treatment. Mexico further encouraged Poland to continue its efforts to ensure compliance of its domestic legislation with the CRC, specifically with regard to juvenile justice. Mexico also invited Poland to consider the ratification of CPD and signing the Optional Protocol thereto. 42. China welcomed efforts to improve the judiciary and to strengthen national human rights mechanisms. China noted with appreciation the constructive cooperation with various treaty bodies and the implementation of the suggestions on torture and equity between men and women. China encouraged Poland to continue to make efforts in promoting and protecting human rights. China had taken note of the fact that some organizations think that there still is discrimination against Jews and people of Asian and African origin, and asked whether Poland has taken any specific measures to improve the situation. 43. Algeria referred to paragraph 2 of the summary prepared by OHCHR, which states that there continue to be racially motivated acts of discrimination against people of African and Asian origin and Roma. Algeria noted the concern of the European Commission against Racism and Intolerance that authorities rarely investigate and prosecute cases of racial hatred and racially motivated crimes. Algeria recommended that Poland fulfil the recommendation, elaborated on in paragraph 2 of the OHCHR summary, made by the Council of Europe Commissioner for Human Rights, who in 2007 called upon Poland to enact a comprehensive body of anti-discrimination legislation and to set up a body to combat discrimination. Algeria further recommended that Poland give adequate training and instruction to law enforcing bodies and to the judiciary on how to address complaints stemming from racially motivated crimes. Algeria referred to paragraph 17 of the compilation report and the concern expressed by CAT about the overcrowding in prisons and noted that pre-trial detention can last up to two years and that there is an absence of legislation for setting a time limit to it. Algeria further referred to the concern about the conditions of detention in transit zones and the lack of specific laws for the detention of aliens. In this regard, Algeria called upon Poland to alleviate the overcrowding of detention centres and to review the conditions of detention centres so that they conform with minimum international standards. Algeria also recommended that limits be set for pre-trial detention according to minimum international standards.
