Nigeria's Prison System Reform Can't Wait

Nigeria's criminal justice system is in dire need of reform, with tens of thousands of individuals languishing in overcrowded prisons, many without ever being convicted of a crime. The situation highlights systemic failures in policing, prosecution, and judicial processes.

Official figures from February 2026 reveal that Nigeria's custodial centers held 80,812 inmates. Of this number, a staggering 51,955, or approximately 64 percent, were awaiting trial. Only 24,913 had been convicted. The number of awaiting-trial inmates had even increased by 1,252 in just two months, underscoring the growing backlog and inefficiency.

Tens of thousands of legally innocent people have spent years in detention under conditions that no civilised society should tolerate.

Further compounding the issue, a 2023 audit revealed that 93 percent of inmates in federal prisons were held for offenses under state laws, despite prisons being federally administered. Many of these individuals, the Minister of Interior noted, should not have been incarcerated at all. The audit also found thousands imprisoned for fines and compensation orders below N500,000.

93 per cent of inmates in Nigeria’s custodial centres were being held for offences under state laws, even though prisons are administered by the Federal Government. Those inmates, he added, should not have been incarcerated in the first place!

The reasons for prolonged pre-trial detention are varied: poorly conducted investigations, lost case files, overwhelmed courts, unprepared prosecutors, and the inability to meet stringent bail conditions. Some inmates remain incarcerated simply because they cannot afford relatively modest fines. This leads to a situation where individuals presumed innocent spend years in squalid, overcrowded cells, only to be acquitted or receive sentences shorter than their pre-trial detention.

The conditions within many correctional centers are described as inhumane. Overcrowding is rampant, leading to the common spread of communicable diseases like tuberculosis. Healthcare is inadequate, nutrition is poor, sanitation is deplorable, and rehabilitation programs are often nonexistent. These dire circumstances have led to preventable deaths, with at least 20 inmates dying of pulmonary tuberculosis in 2022 alone.

This is absurd and inhuman. It is institutionalised injustice.
