A/HRC/23/41 (l) Prevent the detention and deportation of migrant workers based on their health status and ensure the provision of care and treatment to such migrant workers at the first instance. At minimum, States should ensure that migrant workers are not deported without referral for treatment or to States where the required treatment is not available and accessible; (m) Prevent the detention and deportation of irregular migrant workers and instead regularize their stay on objective criteria, in order to protect them from exploitation and ensure their full enjoyment of the right to health; (n) Encourage the establishment of migrant workers associations and trade unions to ensure effective representation and participation of migrant workers, including irregular and returnee migrant workers, in the formulation, implementation, monitoring and enforcement of laws and policies, including outreach and referral programmes, pre-departure sessions and social support groups. 24
