No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment. In particular, no one shall be subjected without his free consent to medical or scientific experimentation.

Everyone has the right to liberty and security of person. No one shall be subjected to arbitrary arrest or detention. No one shall be deprived of his liberty except on such grounds and in accordance with such procedure as are established by law.

All persons deprived of their liberty shall be treated with humanity and with respect for the inherent dignity of the human person.

Those detained in the course of migration proceedings have the right to be informed, in writing and in a language which they understand, of the nature of and grounds for the decision to detain, the duration of detention, as well as of the possibility to challenge the legality and arbitrariness of such decision.

We commit to ensure that any detention in the context of international migration follows due process, is non-arbitrary, based on law, necessity, proportionality, and individual assessments, is carried out by authorized officials, and for the shortest possible period of time, irrespective of whether detention occurs at the moment of entry, in transit, or proceedings of return, and regardless of the type of place where the detention occurs. We further commit to prioritize non-custodial alternatives to detention that are in line with international law, and to take a human rights-based approach to any detention of migrants, using detention as a measure of last resort only.

To realize this commitment, we will draw from the following actions:

(g) Ensure that all governmental authorities and private actors duly charged with administering immigration detention do so in a way consistent with human rights and are trained on non-discrimination and the prevention of arbitrary arrest and detention in the context of international migration, and are held accountable for violations or abuses of human rights.

Detention in the course of proceedings for the control of immigration is not per se arbitrary, but the detention must be justified as reasonable, necessary and proportionate in the light of the circumstances and reassessed as it extends in time. Asylum seekers who unlawfully enter a State party’s territory may be detained for a brief initial period in order to document their entry, record their claims and determine their identity if it is in doubt. To detain them further while their claims are being resolved would be arbitrary in the absence of particular reasons specific to the individual, such as an individualized likelihood of absconding, a danger of crimes against others or a risk of acts against national security. The decision must consider relevant factors case by case and not be based on a mandatory rule for a broad category; must take into account less invasive means of achieving the same ends, such as reporting obligations, sureties or other conditions to prevent absconding; and must be subject to periodic re-evaluation and judicial review. Decisions regarding the detention of migrants must also take into account the effect of the detention on their physical or mental health. Any necessary detention should take place in appropriate, sanitary, non-punitive facilities and should not take place in prisons. The inability of a State party to carry out the expulsion of an individual because of statelessness or other obstacles does not justify indefinite detention. Children should not be deprived of liberty, except as a measure of last resort and for the shortest appropriate period of time, taking into account their best interests as a primary consideration with regard to the duration and conditions of detention, and also taking into account the extreme vulnerability and need for care of unaccompanied minors.
