§ 34. The Committee recommends that the State party: […]

(b) Ensure that administrative detention is used only as a measure of last resort and that non-custodial alternatives are provided, in line with the Committee’s general comment No. 2 (2013) on the rights of migrant workers in an irregular situation and members of their families;

(c) Cease the detention of children on the basis of their or their parents’ immigration status and adopt alternatives to detention that allow children to remain with family members and/or guardians in non-custodial, community-based contexts while their immigration status is being reviewed, in line with the principles of the best interests of the child and the child’s right to family life.

36. The Committee recommends that the State party:

(a) Ensure that all migrant workers and members of their families, particularly those in detention, have recourse to consular support to protect the rights set out in the Convention;
[…]

§ 76. "The Committee urges the State party to take all measures to guarantee the rights
and well-being of internally displaced children. In particular, the State party is urged:
(a) To adopt a comprehensive national policy on IDPs which, inter alia,
identifies the agency responsible for the registration, monitoring and protection
of IDPs, including children;
(b) To ensure that, until such policy is in place, the National Commission for
Refugees (NCFR) and the Nigerian Red Cross are provided with the necessary
resources to effectively protect and ensure the rights of internally displaced
children."

41, recommends that the State party:

(a) Decriminalize irregular migration and make provision for appropriate
administrative penalties for such offences, since the Committee considers that, in
accordance with its general comment No. 2 (2013) and its general comment No. 5 (2021),
inter alia, irregular entry or stay or exit may constitute administrative offences at most
and should never be considered criminal offences, as they do not infringe upon
fundamental, legally protected values and, as a result, are not crimes per se against
persons, property or national security;
(b) Adopt measures to phase out, and ultimately put an end to, immigration
detention; and enact a presumption in law against detention and therefore in favour of
freedom;
(c) Immediately cease immigration detention of children, whether
unaccompanied, separated from their parents, or together with their families, and of
other vulnerable groups of migrant workers and members of their families as well as
asylum-seekers, refugees and stateless persons;
(d) Ensure that:
(i) In all other cases, the detention of migrants is an exceptional measure of last resort, pursuing a legitimate end permitted by law, and that it is necessary and proportionate, and applied for the shortest possible period of time;
(ii) The grounds for detention are specified in each case, with specific reasons why alternative measures cannot be implemented;
(iii) The measure is reviewed within 24 hours by an independent and impartial judicial authority;
(iv) In line with its human rights obligations, alternative measures to detention are considered and made use of before imposing detention measures. The Committee recognizes alternatives to detention as being all community-based care measures or non-custodial accommodation solutions – in law, policy or practice – that are less restrictive than detention and that must be considered in the context of lawful detention decision procedures to ensure that detention is
necessary and proportionate in all cases, with the aim of respecting the human rights and avoiding the arbitrary detention of migrants, asylum-seekers, refugees and stateless persons;
(e) Ensure that alternative measures to detention are applied to asylum-seekers and refugees, and in all cases of voluntary return, and that migrant workers and members of their families are informed of their rights and about procedures in the detention context in a language they understand;
(f) In exceptional cases where detention cannot be avoided, ensure that all
immigration detention facilities are officially designated for this purpose, guarantee
adequate and decent conditions, such as gender-responsive health services, including
sexual and reproductive health services, psychological care, water, sanitation and
hygiene, food, sufficient space and ventilation, leisure and recreational activities and
access to outdoor areas;
(g) Strictly separate detention regimes from “voluntary” placement in “migration screening centres”, including in statutory law, and provide for State-run or community-run shelters, which are physically separated from an immigration detention centre and are not situated on the same premises;
(h) Ensure that women detainees are held separately from men, are guarded only by adequately trained women officers and are protected against violence, in particular sexual violence, and that specific provisions are made for pregnant and nursing women;
(i) Strengthen mechanisms to regularly monitor conditions in migrant detention centres and grant human rights monitors, including humanitarian agencies, the National Human Rights Commission, and non-governmental organizations, unannounced and unhindered access to all migrant detention centres.
