Those detained in the course of migration proceedings must be treated without discrimination based on race, colour, sex, property, birth, age, national, ethnic or social origin, language, religion, economic condition, political or other opinion, sexual orientation or gender identity, disability, nationality or any other status, or on any ground that aims at or may result in undermining the enjoyment of human rights on the basis of equality.

All detained migrants must be treated humanely and with respect for their inherent dignity. The conditions of their detention must be humane, appropriate and respectful, noting the non-punitive character of the detention in the course of migration proceedings. Detention conditions and treatment must not be such as to impede the ability to challenge the lawfulness of detention, and detention should not be used as a tool to discourage asylum applications.

The different categories of prisoners shall be kept in separate institutions or parts of institutions taking account of their sex, age, criminal record, the legal reason for their detention and the necessities of their treatment. Thus,

(a) Men and women shall so far as possible be detained in separate institutions; in an institution which receives both men and women the whole of the premises allocated to women shall be entirely separate;

(b) Untried prisoners shall be kept separate from convicted prisoners;

(c) Persons imprisoned for debt and other civil prisoners shall be kept separate from persons imprisoned by reason of a criminal offence;

(d) Young prisoners shall be kept separate from adults.

The medical officer shall see and examine every prisoner as soon as possible after his admission and thereafter as necessary, with a view particularly to the discovery of physical or mental illness and the taking of all necessary measures; the segregation of prisoners suspected of infectious or contagious conditions; the noting of physical or mental defects which might hamper rehabilitation, and the determination of the physical capacity of every prisoner for work.

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:

(f) Reduce the negative and potentially lasting effects of detention on migrants by guaranteeing due process and proportionality, that it is for the shortest period of time, that it safeguards physical and mental integrity, and that, at a minimum, access to food, basic health care, legal orientation and assistance, information and communication as well as adequate accommodation is granted, in accordance with international human rights law.
