1.0 INTRODUCTION
“Vincent, if the Ministry of Justice knows and finds out that you are getting their laws and making use of it and explaining them to people, won’t they arrest you?”
My mother asked me this recently. She was serious and probably scared. This comes after a recent experience bound with fears and trauma.
I laughed at first, the question seemed absurd to me but within me I realized that “it is what many Nigerians like her are meant to believe their whole life”. I had spent months inside the ministry of justice, studying their field, accompanying prosecutors to court. The law was not a secret. It was not a weapon hidden from citizens. It was… just there. Available. Public and easy to access. No limitation accessing those laws.
But then I stopped laughing.
My mother’s question revealed something painfully; most Nigerians do not know their rights, especially within the Criminal Justice system. They do not know that the law is not a mysterious tool used only by the powerful. They do not know that they have the legal right and backing to understand the process that can take away their liberty, their property, even their lives. They fear law because they do not know it. They are unaware that the law is there to protect them. Even the law that convicts and sentences a guilty person, is the same law that protects their right while in prison and out of prison. Therefore, how much more of a person who tends to read, know and make use of the law to defend his or her right.
Conclusively, this guide is my answer to my mother and every Nigerian who has ever wondered, feared being traumatized, or stayed silent or said to leave everything to God because they did not know what the law says about their rights. This guide shall give elaborate steps and guides for citizens to better understand their right within the Criminal Justice system in Nigeria while dealing with law enforcement agencies, court, prison and the outside world.
2.0 DEFINITION OF CRIMINAL AND THE CRIMINAL JUSTICE SYSTEM
Who is a Criminal?
A Criminal is a person or an individual who has committed a crime or has been legally convicted of a crime (according to Oxford dictionary).
In the context of criminology and criminal justice, a criminal is a person who has been ‘convicted’ of a crime by a reputable and competent court of law, having considered and reviewed the case and evidence brought before it. However, a person is presumed innocent until proven guilty by a competent court of law.
2.1 WHAT DO WE UNDERSTAND BY THE CRIMINAL JUSTICE SYSTEM?
The Criminal Justice System as a criminological concept of justice, is defined as the process which involves, necessitates, and initiates the ‘investigation of crime’, ‘arrest’, ‘prosecution’, and possible ‘incarceration of offenders’, as obligated and mandated by the Criminal Law of a country. (Faloye Vincent Adetomide, 2026).
The Criminal Justice System (CJS) is a triangular or circular section that defines crime and shows the steps in which the crime would be taken care of. The Criminal justice system (CJS) involves a triangular or circular relationship that exists among the ‘police’, the ‘court’, and the ‘prison’.
This shows that the Police is the first point of contact in the CJS, following the investigation and arrest of a suspect, they are charged to court.
2.2 EXPLANATION
The Police are saddled with the responsibility of enforcing the law, detecting crime, investigating crime, and arresting the offenders. The Police Act, 2020, which grants the exclusive powers of the Nigeria Police Force. The Police Act is an enabling statute that defines, describes, provides for, and spells out the operation of the Nigerian Police Force, their powers and limits. They are to operate within the limits of their constitutional and statutory roles and functions.
It is stated as follows in reference to The Police Act, 2020:
General Duties of the Police: According to Section 4, the Police shall be employed for the prevention and detection of crime, the apprehension of offenders, the preservation of law and order etc. which they are directly charged with.
Power to Investigate Crime: According to Section 31, grant the police the power to investigate crime. That is, a police officer may investigate any alleged crime.
Power to Arrest: Section 32(1), grant the police the power to make an arrest or power of arrest. Section 38(1) further made explicit that a police officer may, without an order of a court and without a warrant, arrest a suspect. However, the “without a warrant” is subject to a specific condition or circumstance set or laid out in the Police Act, Administration of Criminal Justice Act, 2015 (ACJA), and other enactments such as the Criminal Code Act.
Note: Under section 32(2) of the Police Act, “a person shall not be arrested merely (simply) on a civil wrong or breach of contract.”
In addition, under Section 7 and Section 36 of the ACJA 2015 and The Police Act 2020 respectively, provided for; “Arrest in lieu prohibited” this specifically means that ‘A person shall not be arrested in place of a suspect’. What this means is that, a family member or friend to a ‘suspect’ of a crime shall not be arrested in place of or instead of the actual suspect.
In furtherance, under Article 9 of the United Nation’s “Universal Declaration of Human Right (UDHR)”, to which Nigeria is a party, provided for the following regarding arrest; “No one shall be subjected to arbitrary arrest, detention or exile”. Therefore, in addition to this provision, under Section 35(6) of the Constitution of the Federal Republic of Nigeria, it states; “Any person who is unlawfully arrested or detained shall be entitled to compensation and public apology from the appropriate authority or person.” Thus, this further explained that no person (citizen or aliens) in the country shall be subjected to any inhuman treatment in the cause of arrest, or arrested or detained arbitrary or unlawfully without due process being followed by law enforcement agencies, and such person or aliens shall be entitled to be compensated for harm suffered including psychological and emotional harm being experienced by the person or aliens.
The Court, in its stead, interprets the law and makes the trial of the offender efficient and possible, while ensuring a fair trial (fair hearing) provided under section 36(1) of the Constitution of the Federal Republic of Nigeria, and their eventual sentencing (adjudication). The Constitution Of The Federal Republic Of Nigeria, provided for the third arms of government which is the ‘Judiciary’ of which “The Court” is summarily ascribed to and mandated with the constitutional provision and power to tried a person accused of crime and hear the charge against the person and to deliver judgement against or in favour of the accused. With such courts having a hierarchical supremacy and independent of the other arms of government. Section 230 to 284 of the Constitution, which grants the court jurisdiction and power to hear all types of criminal cases and appeals.
The Prison, also known as a correctional institution, provides the atmosphere for either punishing or treating the offender and/or possible incarceration as adjudged by the trial court.
Every modern society has a Criminal Justice System. Let us take the family as an example to substantiate our reference (parents sanctioning children), which exercises formal social control by meting out punishment to any of their deviant or recalcitrant wards. Thus, this system also shapes offenders behaviour, the police, the court, and the correctional system also contribute to the development of this system, specifically the modern age.
The system within the prison may reduce crime by giving criminals skills acquisition; on the other hand, a prison sentence could contribute to crime by creating a desire for revenge to strike back at the society. This generally depends on the kind of orientation the prisoner is subjected to while in prison.
3.0 ELEMENT OF THE CJS
The Criminal Justice System has five components, and each of it performs a key role in the Criminal Justice System in Nigeria. Each created by laws or an act of the National Assembly and the State House of Assembly.
(1) Law Enforcement:
Law enforcement officers’ takes reports of crimes that happen in their jurisdictions. These officers investigate the crime, gather evidence from the crime scene, and protect evidence from possible contamination or damage, and also protect witnesses to the crime (either the victim or a passerby). Law enforcement agencies may arrest offenders, give testimony during court process (proceedings), and conduct follow-up investigation if need be. These law enforcement or security agencies are: The Police (the most common), The Nigeria Security And Civil Defence Corps, State Security Service, Amotekun (Southwest Security Network), and The Southeast Security Network, NAPTIP, NDLEA, Nigeria Customs etc.
Note: All the above mentioned law enforcement agencies follow the same process and are bound by the same statutory and constitutional provision. In summary, all persons (citizens) including law enforcement officers are equal before the law and governed under one “Constitution”, which is the supreme law of the land. The Constitution is based on the principles of democracy, and the rule of law.
(2) Prosecution:
Prosecutors are lawyers who represent the federal, state, or local government throughout the court process, right from the first appearance of the accused in court until the accused is acquitted, convicted or sentenced, respectively. In Furtherance, under Section 174(1a) and Section 211(1a) of the 1919 Constitution of the Federal Republic of Nigeria, which grants the Attorney-general at both the State and Federal level the power to institute and undertake criminal proceedings against any person before any court of law in Nigeria.
The prosecutor reveals or presents the evidence brought to them by the law enforcement agents or officers to decide whether to file charges or drop them. In this instance, the prosecutors must prove his case ‘beyond a reasonable doubt’, by presenting strong evidence that links the accused to the said crime. As the burden of proof lies mainly on the prosecution.
In addition, the prosecutor presents evidence in court, questions witnesses and decides whether to negotiate, or enter into a ‘plea bargain’ with the defendants.
Note: Pursuant to Article 11(2) of the UDHR 1948, states that “No one shall be held guilty of any penal offence on account of any act or omission which did not constitute a penal offence, under national or international law, at the time when it was committed. Nor shall a heavier penalty be imposed than the one that was applicable at the time the penal offence was committed”. Therefore, before a person is charged or prosecuted in court for a particular offence. The said crime has to be recognized and in effect and enacted by an act of the National Assembly (NASS) or the State House of Assembly (HoS) resident in every state of the federation. Therefore, arresting and charging a person over a said offence not recognized or enacted is grossly invalid and unconstitutional.
For instance, there is no law barring a citizen or criminalizing videoing an officer during their lawful duty, (every citizen or aliens resident in a country have the right to receive and impart information and ideas through any media and regardless of frontiers, this is provided under Article 19 of the UDHR 1948). So for such to be considered a criminal offence, the NASS or the HoS have to pass such into law and ‘assented’ by the president or the state governor. Therefore, no illegal laws shall be made without passing through the due process of law and in conformity with the Constitution and international laws.
(3) Defence Attorney
The defence attorney is the accused lawyer or counsel. The defense attorney defends the accused against the government. In some jurisdictions, the defence lawyer is responsible for proving the innocence of his/her client (the accused), that means the burden of proof lies on the defendant. However, in Nigeria current practice, the burden of proof lies on the Prosecution while the defence lawyer will have the opportunity to oppose or object to any accusation or evidence brought before the court by the prosecution.
Under section 36(6c) of the 1999 Constitution of the Federal of Nigeria, provided that;
“Every person who is charged with a criminal offence shall be entitled to defend himself in person or by legal practitioners of his own choice.”
In pursuant of the above provision, they are either hired by the defendant or provided for by the government, (this is in case the defendant cannot afford the service of a personal lawyer), and therefore, they are assigned by the court through the public defendant or by Legal aid council residence in the state of the defendant. In reference to the Administration of Criminal Justice Act, 2015, Section 349(1b), state as follows;
“Where a defendant charged before the court is not represented by a legal practitioner, the court shall enquire from him, whether he wishes to engage his own legal practitioner, or a legal practitioner engaged for him by way of legal aid.”
Note: This is an important and potent process in the Criminal Justice System, the constitution has made it a general compliance and mandate, that any person who has been arrested for any offence known to the law, such person shall have the right and power to defend him or herself by any legal practitioners of his own choice. This is where the rule of law and the Criminal Procedure Act (CPA) should take effect.
The rule of law state that; there should be “supremacy of the constitution”, that is, the constitution is supreme and it is above all other human, secondly, the “equality of every person before the law”, this means for the supremacy of the constitution, every person is equal before the law and is subjected and answerable to the constitution, lastly, to ensure the “fundamental human right of citizen”; this is one of the provision of the constitution and the foremost United Nation’s Universal Declaration of Human Right (UDHR) 1948, which is directly linked to the after arrest of a suspect; ‘right to dignity of his person’, ‘right to freedom from torture or to cruel, inhuman or degrading treatment or punishment’, ‘right to have accessed to their own legal representation’.
(4) The Court:
The courts are run by judges whose role is to make sure that law is followed and oversee what happens in court and preside over a case in court. They decide whether to release offenders before the trials. The presiding judges either accept or reject plea bargaining, oversee trials and sentence guilty offenders. There are two categories of inmates. They are ‘Awaiting trial and the convicted’.
(5) Correctional Institutions (Prison):
Correctional officers supervise convicted offenders when they are in jail, prison, in the community on probation or parole. According to the Nigerian Correctional Service Bill, 2018, made for the provision of the Nigerian Correctional Service, under Section 1 and its primary goal as a correctional service in Nigeria under Section 10 (a-k).
The Criminal Justice System is incomplete without the circumstance involving the prison and or a rehabilitation centre. Under the Administration of Criminal Justice Act, 2015, Section 467(1) describes the position of a Correctional Centre (institution) in the Criminal justice system.
“A defendant convicted of an offence triable summarily may be sentenced and ordered to serve the sentence at a Rehabilitation and Correctional Centre established by the Federal Government in lieu of imprisonment.”
In some jurisdictions, correctional officers prepare, present a criminal report with extensive and detailed background information or activities about the offender to help the judges decide his or her sentence.
