9(1)
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.
16(1)
Migrant workers and members of their families shall have the right to liberty and security of person.
16(4)
Migrant workers and members of their families shall not be subjected individually or collectively to arbitrary arrest or detention; they shall not be deprived of their liberty except on such grounds and in accordance with such procedures as are established by law.
37(b)
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.
P14
Detention in the course of migration proceedings must be justified as reasonable, necessary and proportionate in the light of the circumstances specific to the individual case. Such detention is permissible only for the shortest period of time, it must not be punitive in nature and must be periodically reviewed as it extends in time.
P20
Detention in the course of migration proceedings must be prescribed by law, justified as reasonable, necessary and proportionate in the light of the circumstances and reassessed as it extends in time. These cumulative elements must be complied with in each individual case.
P23
The element of necessity requires that the detention be absolutely indispensable for achieving the intended purpose and that no other measure less onerous exists in the individual circumstances of the person who is in an irregular migration situation.

1. A person may only be deprived of his/her liberty, with a view to ensuring that a removal order will be executed, if this is in accordance with a procedure prescribed by law and if, after a careful examination of the necessity of deprivation of liberty in each individual case, the authorities of the host state have concluded that compliance with the removal order cannot be ensured as effectively by resorting to non-custodial measures such as supervision systems, the requirement to report regularly to the authorities, bail or other guarantee systems.

2. The person detained shall be informed promptly, in a language which he/she understands, of the legal and factual reasons for his/her detention, and the possible remedies; he/she should be given the immediate possibility of contacting a lawyer, a doctor, and a person of his/her own choice to inform that person about his/her situation.

1. Any detention pending removal shall be for as short a period as possible.

2. In every case, the need to detain an individual shall be reviewed at reasonable intervals of time. In the case of prolonged detention periods, such reviews should be subject to the supervision of a judicial authority.

1. Persons detained pending removal should normally be accommodated within the shortest possible time in facilities specifically designated for that purpose, offering material conditions and a regime appropriate to their legal situation and staffed by suitably qualified personnel.

2. Such facilities should provide accommodation which is adequately furnished, clean and in a good state of repair, and which offers sufficient living space for the numbers involved. In addition, care should be taken in the design and layout of the premises to avoid, as far as possible, any impression of a 'carceral' environment. Organised activities should include outdoor exercise, access to a day room and to radio/television and newspapers/magazines, as well as other appropriate means of recreation.

3. Staff in such facilities should be carefully selected and receive appropriate training. Member states are encouraged to provide the staff concerned, as far as possible, with training that would not only equip them with interpersonal communication skills but also familiarise them with the different cultures of the detainees. Preferably, some of the staff should have relevant language skills and should be able to recognise possible symptoms of stress reactions displayed by detained persons and take appropriate action. When necessary, staff should also be able to draw on outside support, in particular medical and social support.

4. Persons detained pending their removal from the territory should not normally be held together with ordinary prisoners, whether convicted or on remand. Men and women should be separated from the opposite sex if they so wish; however, the principle of the unity of the family should be respected and families should therefore be accommodated accordingly.

5. National authorities should ensure that the persons detained in these facilities have access to lawyers, doctors, non-governmental organisations, members of their families, and the UNHCR, and that they are able to communicate with the outside world, in accordance with the relevant national regulations. Moreover, the functioning of these facilities should be regularly monitored, including by recognised independent monitors.

6. Detainees shall have the right to file complaints for alleged instances of ill-treatment or for failure to protect them from violence by other detainees. Complainants and witnesses shall be protected against any illtreatment or intimidation arising as a result of their complaint or of the evidence given to support it.

7. Detainees should be systematically provided with information which explains the rules applied in the facility and the procedure applicable to them and sets out their rights and obligations. This information should be available in the languages most commonly used by those concerned and, if necessary, recourse should be made to the services of an interpreter. Detainees should be informed of their entitlement to contact a lawyer of their choice, the competent diplomatic representation of their country, international organisations such as the UNHCR and the International Organization for Migration (IOM), and non-governmental organisations. Assistance should be provided in this regard.
II.108
Any restrictions on the liberty of non-nationals, including migrants regardless of their migration status, asylum seekers, refugees and stateless persons, is to be a measure of last resort, necessary and proportionate, and imposed only where less restrictive alternatives have been considered and been found to be inadequate to meet legitimate purposes.
O13
Use migration detention only as a measure of last resort and work towards alternatives.
O13.29(c)
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.
33
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.
18
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.
10
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.
11
Instead, States should adopt solutions that fulfil the best interests of the child, along with their rights to liberty and family life, through legislation, policy and practices that allow children to remain with their family members and/or guardians in non-custodial, community-based contexts while their immigration status is being resolved and the children’s best interests are assessed, as well as before return. When children are unaccompanied, they are entitled to special protection and assistance by the State in the form of alternative care and accommodation in accordance with the Guidelines for the Alternative Care of Children. When children are accompanied, the need to keep the family together is not a valid reason to justify the deprivation of liberty of a child. When the child’s best interests require keeping the family together, the imperative requirement not to deprive the child of liberty extends to the child’s parents and requires the authorities to choose non-custodial solutions for the entire family.
