News stories about a detainee being denied access to their doctor — like the reports around a high-profile ICPC detention in Nigeria — raise a question most people can't answer precisely: what is the legal floor for anyone in custody, anywhere? This explainer covers the Nigerian constitutional rules and the international minimum standards, without taking sides in any specific case.
The UN's Mandela Rules (Rules 24–27) set the global minimum: detainees are entitled to the same standard of health care available in the community, free of charge, and clinical decisions may only be taken by health-care staff — not by the detaining agency. Nigeria's Anti-Torture Act 2017 and Section 34 of the 1999 Constitution (dignity of the person) point the same way: denying urgent care can amount to inhuman or degrading treatment.
Section 35(2) of the Nigerian Constitution guarantees the right to remain silent and consult a lawyer of your choice before answering questions. The Administration of Criminal Justice Act 2015 (s.6, s.14) requires notification of this right at arrest.
Section 35(4)–(5): a person arrested must be brought before a court within a "reasonable time" — defined as 24 hours where a court sits within 40 km, otherwise 48 hours. Continued detention beyond that needs a court order, and courts can grant bail or order release.
Section 34 (no torture, no inhuman or degrading treatment) plus the African Charter on Human and Peoples' Rights, Article 5, which Nigeria has domesticated into national law — meaning it is directly enforceable in Nigerian courts.
Agencies may use their own medical staff for routine care, but the Mandela Rules require clinical independence, and Nigerian courts have ordered access to personal physicians where the detainee's condition demands specialist continuity. Refusing all access during a medical emergency is the clearest violation.
A fundamental rights enforcement application under the Fundamental Rights (Enforcement Procedure) Rules 2009 — heard quickly, can order access, release, or compensation. Habeas corpus also remains available.
No. Every protection above applies from the moment of arrest, before any trial. Due process exists precisely because guilt hasn't been established yet — it protects the innocent and the guilty alike, which is the point.
