A/HRC/26/29 right can, however, be in tension with laws regulating cross-border activities such as immigration and trade. For example, pastoralist communities whose territories or means of livelihood straddle international borders often do not use formal border crossing points or possess the necessary administrative documentation such as passports. The Special Rapporteur is unconvinced that border control laws should automatically trump their ability to maintain their cultural lifestyles. He believes that States have an obligation to facilitate the free movement of such communities, including by adopting special measures recognizing cross-border movements in the context of transhumance. 62. The Special Rapporteur further decries the discriminative and disproportionate use of immigration laws by States to deny residence or work permits to staff of associations that are critical of the Government or that express views that are unpopular with the Government. 63. As stated by the Human Rights Council, in its resolution 24/5, the right to freedom of association applies both online and offline. As such, laws that unjustifiably restrict freedom of expression on the Internet and limit the ability of people to associate over that medium are unacceptable. With youth being the most active social media users overall, restrictions placed on access to social media sites will disproportionately affect their ability to organize and mobilize for their common interests. The perception that youth in general lacks maturity and are therefore incapable of participating fully in public affairs often forms the backdrop against which some Governments feel the need to filter and dictate media content made available in their countries. 64. In addition to legislation that restricts the right to the freedom of assembly of LGBTI people through discriminatory law that prohibits “propaganda” or the “promotion” of homosexuality, some legislation also specifically prohibits the formation, running, participation in or support of organizations that advocate for the protection of the human rights of LGBTI people. This is the case of the above-mentioned Same Sex Marriage (Prohibition) Act in Nigeria. The Special Rapporteur highlights that the Human Rights Committee has clarified that any limitations to rights protected by the International Covenant on Civil and Political Rights, when permitted by the Covenant, may not be imposed for discriminatory purposes or applied in a discriminatory manner. Therefore, provisions restricting or prohibiting the right to freedom of association of a specific group on discriminatory grounds, such as sexual orientation or gender identity, is not permitted under the Covenant and must be reviewed with a view to repeal. 4. Practices threatening and impeding the enjoyment of the right to freedom of association 65. The lived experiences of members of groups most at risk may be problematic even where legislation promotes equality and non-discrimination, due to practices that threaten and impede the enjoyment of the right to freedom of association. Such practices can lead to the marginalization of groups already disadvantaged in their exercise of the right to freedom of association. The conditions of work for migrant domestic workers, for example, are often characterized by isolation and dependence. This is reinforced by unfamiliarity with the work environment of the host country and a lack of basic support structures, which then encourage bad practices by employers, such as restricting the freedom to leave the workplace. Women migrant workers face gender-based violence and abuse, and migrant domestic workers in irregular situations are further at risk of deportation. They are therefore even less likely to speak out against exploitation and abuse. In these circumstances, migrant workers are faced with considerable obstacles in their efforts to form associations that cater for their interests. Refugees and asylum seekers find themselves in a similar situation where the fear of their status being revoked has a chilling effect on their ability to mobilize. 18
