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.

Everyone lawfully within the territory of a State shall, within that territory, have the right to liberty of movement and freedom to choose his residence.

Migrant workers and members of their families shall have the right to liberty and security of person.

1. Migrant workers and members of their families shall have the right to liberty of movement in the territory of the State of employment and freedom to choose their residence there.

2. The rights mentioned in paragraph 1 of the present article shall not be subject to any restrictions except those that are provided by law, are necessary to protect national security, public order (ordre public), public health or morals, or the rights and freedoms of others and are consistent with the other rights recognized in the present Convention.

No child shall be deprived of his or her liberty unlawfully or arbitrarily. The arrest, detention or imprisonment of a child shall be in conformity with the law and shall be used only as a measure of last resort and for the shortest appropriate period of time.

States Parties shall ensure that persons with disabilities, on an equal basis with others:

a) Enjoy the right to liberty and security of person;

b) Are not deprived of their liberty unlawfully or arbitrarily, and that any deprivation of liberty is in conformity with the law, and that the existence of a disability shall in no case justify a deprivation of liberty.

Arrest, detention or imprisonment shall only be carried out strictly in accordance with the provisions of the law and by competent officials or persons authorized for that purpose.

Any form of administrative detention or custody in the context of migration must be applied as an exceptional measure of last resort, for the shortest period and only if justified by a legitimate purpose, such as documenting entry and recording their claims or initial verification of identity if in doubt.

Alternatives to detention must be sought to ensure that the detention is resorted to as an exceptional measure.

Use migration detention only as a measure of last resort and work towards alternatives.

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:

(c) Review and revise relevant legislation, policies and practices related to immigration detention to ensure that migrants are not detained arbitrarily, that decisions to detain are based on law, are proportionate, have a legitimate purpose, and are taken on an individual basis, in full compliance with due process and procedural safeguards, and that immigration detention is not promoted as a deterrent or used as a form of cruel, inhumane or degrading treatment of migrants, in accordance with international human rights law.

Reaffirming that all individuals who have crossed or are seeking to cross international borders are entitled to due process in the assessment of their legal status, entry and stay, we will consider reviewing policies that criminalize cross border movements. We will also pursue alternatives to detention while these assessments are under way. Furthermore, recognizing that detention for the purposes of determining migration status is seldom, if ever, in the best interest of the child, we will use it only as a measure of last resort, in the least restrictive setting, for the shortest possible period of time, under conditions that respect their human rights and in a manner that takes into account, as a primary consideration, the best interest of the child, and we will work towards the ending of this practice.

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.

Article 37(b) of the Convention of the Rights of the Child establishes the general principle that a child may be deprived of liberty only as a last resort and for the shortest appropriate period of time. However, offences concerning irregular entry or stay cannot under any circumstances have consequences similar to those derived from the commission of a crime. Therefore, the possibility of detaining children as a measure of last resort, which may apply in other contexts such as juvenile criminal justice, is not applicable in immigration proceedings as it would conflict with the principle of the best interests of the child and the right to development.
