ONSA: FG Secures 1,721 Terrorism Convictions Through Mass Trial Programme

The Federal Government of Nigeria has announced a significant milestone in its counter-terrorism efforts, securing 1,721 terrorism-related convictions since the inception of its Mass Trial Programme in October 2017. This disclosure was made by the Director, Legal Services, Office of the National Security Adviser (ONSA), Zakari Mijinyawa. The programme, a collaborative effort involving ONSA, the Federal Ministry of Justice, the Judiciary, and various security agencies, has completed ten phases of trials, with a notable acceleration in convictions in 2026. While the government emphasizes adherence to due process and fair trial standards, the programme has also drawn scrutiny regarding the procedural fairness and human rights implications inherent in mass adjudication processes for complex terrorism cases.

Nigeria's protracted battle against terrorism, primarily spearheaded by groups like Boko Haram and the Islamic State West Africa Province (ISWAP), has necessitated robust legal and security responses. In a recent development, the Federal Government, through the Office of the National Security Adviser (ONSA), announced that its Mass Trial Programme, initiated in October 2017, has resulted in 1,721 terrorism-related convictions. This figure represents a substantial outcome in the nation's efforts to bring alleged terrorists to justice and underscores the government's commitment to a criminal justice approach in combating insurgency.

The Mass Trial Programme, a coordinated initiative involving key governmental and judicial bodies, aims to address the backlog of terrorism cases and ensure accountability for severe offences. The reported convictions are presented as evidence of the programme's effectiveness and the government's resolve to uphold the rule of law while tackling national security threats. However, the scale and nature of these trials inevitably raise pertinent questions for legal practitioners regarding due process, fair hearing guarantees, and the broader implications for Nigeria's criminal justice system.

The legal framework for combating terrorism in Nigeria has evolved significantly over the past decade. Initially, the Terrorism Prevention Act of 2011 provided the foundational legislation, which was subsequently amended by the Terrorism Prevention (Amendment) Act of 2013. These Acts established measures for the prevention, prohibition, and combating of terrorism, including provisions for terrorist financing and the seizure of assets. More recently, the Terrorism (Prevention and Prohibition) Act of 2022 repealed the earlier Acts, further strengthening the legal architecture and establishing a National Terrorism Coordination Center under the Office of the National Security Adviser (ONSA). The ONSA is statutorily mandated to coordinate all security and enforcement agencies in the fight against terrorism.

The Mass Trial Programme itself commenced in October 2017, largely in response to the overwhelming number of individuals detained in connection with the Boko Haram insurgency. The initial phases of these trials were conducted in military facilities, such as the Wawa Cantonment in Kainji, Niger State. The programme is a collaborative effort between ONSA, the Federal Ministry of Justice, the Judiciary, security agencies, and international partners, reflecting a multi-agency approach to complex national security prosecutions. The government has consistently affirmed its commitment to conducting these trials in line with constitutional guarantees of fair trial and due process, ensuring that defendants are discharged or acquitted where guilt is not established beyond reasonable doubt.

The reported 1,721 terrorism convictions, accumulated over ten phases of the Mass Trial Programme since 2017, represent a substantial output from Nigeria's criminal justice system in its fight against terrorism. The Director of Legal Services at ONSA, Zakari Mijinyawa, highlighted a phased progression, noting 366 convictions in the first three phases (2017-2018), 490 convictions in phases four to eight (2023-2025), and a remarkable 865 convictions in phases nine and ten (2026 alone), which accounts for over half of the total. These later phases also expanded to include convictions for terrorism financing, international crimes, and sexual and gender-based violence, reflecting the evolving nature of terrorism-related offences.

While the government emphasizes its adherence to due process and fair trial standards, including the discharge or acquittal of defendants where guilt was not proven, the very nature of "mass trials" has consistently raised concerns among human rights organizations and legal observers. Criticisms have historically focused on issues such as closed-door proceedings, limited access for media and the public, weak investigations, arbitrary arrests, prolonged unlawful detention, and inadequate legal aid for defendants. Reports from organizations like the Institute for Security Studies (ISS) have pointed to challenges including rushed proceedings, a limited number of judges handling thousands of cases, and a reliance on confessional statements rather than robust evidence.

The Terrorism (Prevention and Prohibition) Act 2022, which now governs these proceedings, provides for severe penalties, including capital punishment for certain terrorist offences where death results from the act. This underscores the gravity of the charges and the imperative for scrupulous adherence to fair trial principles, which are also enshrined in the Nigerian Constitution and international human rights instruments like the UN Global Counter-Terrorism Strategy. The tension between the need for expeditious justice in the face of widespread insurgency and the constitutional guarantees of individual rights remains a critical point of analysis for legal professionals. The sheer volume of convictions, particularly the acceleration in 2026, prompts further inquiry into the resources allocated to ensure quality legal representation and judicial oversight in each case.

The coordination between ONSA, the Federal Ministry of Justice, and the Judiciary is crucial for the programme's legitimacy. The ONSA's role as the central coordinating body for national security matters, as established by the Terrorism (Prevention) (Amendment) Act 2013 and reinforced by the 2022 Act, positions it at the forefront of these legal battles. However, the effectiveness of this coordination in safeguarding individual rights within a mass trial context, particularly concerning evidence gathering, witness protection, and the provision of competent legal defence, requires continuous scrutiny. The reported discharges and acquittals, while affirming a commitment to due process, must be weighed against the systemic challenges inherent in processing such a large number of complex cases.

The Federal Government's announcement of 1,721 terrorism convictions through its Mass Trial Programme marks a significant development in Nigeria's ongoing efforts to combat insurgency and reinforce the rule of law. For legal practitioners, this achievement highlights the intensified focus on prosecuting terrorism-related offences under the Terrorism (Prevention and Prohibition) Act 2022 and its predecessors. The sheer volume of cases processed underscores the capacity and coordination challenges within the justice system, particularly concerning the balance between national security imperatives and fundamental human rights.

Practitioners should remain vigilant regarding the procedural aspects of these mass trials, advocating for transparency, robust legal representation, and strict adherence to fair trial standards. The reported increase in convictions, especially in the latest phases, suggests a sustained and perhaps accelerated judicial response. Moving forward, it will be crucial to monitor the long-term impact of these trials on Nigeria's criminal jurisprudence, the rehabilitation of those acquitted or discharged, and the continued evolution of legal and policy frameworks to ensure justice is not only done but is also seen to be done, even in the most challenging national security contexts.
