Ignorance of the law is no excuse: teaching of criminal law in Ghana must not be reserved for only law students

The maxim ignoratia juris non excusat, which translates to "ignorance of the law is no excuse," remains one of the most entrenched principles of Ghana’s criminal justice system. It simply means that individuals cannot claim ignorance of a law's existence to escape criminal liability. The rationale behind this principle is both practical and philosophical. Practically, the administration of justice would struggle to function effectively if ignorance were accepted as a legitimate defense. If courts were to allow individuals to escape liability by claiming unawareness of a legal rule, the justice system would collapse under a flood of such excuses. No judge could reliably distinguish between genuine ignorance and feigned ignorance, thus undermining the rule of law through uncertainty.

Philosophically, the maxim presumes that the law is a body of public rules that every citizen has a duty to know, and which the state has made accessible through publication and enforcement. However, this presumption becomes problematic when citizens have no realistic opportunity to learn about the law in the first place. In Ghana, while this principle continues to be invoked by courts and law enforcement authorities, most citizens pass through the educational system with little to no structured knowledge of the criminal law that regulates their everyday conduct.

This disconnection between legal obligation and educational preparation has profound implications for justice, citizenship, and social development. Although the National Commission for Civic Education (NCCE), under the authority of Article 233 of the 1992 Constitution of Ghana and the National Commission for Education Act, 1993 (Act 489), seeks to promote awareness of civic duties and rights, its programs are largely ad hoc, insufficiently funded, and often fail to reach large sections of the population. Consequently, the majority of Ghanaians remain unaware of the very laws that govern their conduct, exposing them to potential criminal liability and eroding the moral legitimacy of the criminal justice system.

Misconceptions about criminal law are widespread among the general population. A striking example can be found in the area of sexual offenses. Many young people assume that rape merely refers to sexual intercourse without consent, while defilement applies only if a child under sixteen years is forced. Even more dangerously, some believe that sexual intercourse with a minor is lawful if the minor consents.

The Criminal Offences Act, 1960 (Act 29), however, defines rape in section 97 as "having the carnal knowledge of a female of sixteen years or above without her consent." Section 101(1) states that defilement is the natural or unnatural carnal knowledge of any child under sixteen years of age. Section 101(2) further clarifies that "Whoever naturally or unnaturally carnally knows any child under sixteen years of age, whether with or without his or her consent commits an offence and shall be liable on summary conviction to imprisonment for a term of not less than seven years and not more than twenty-five years." From this, it is evident that in defilement cases, consent is legally irrelevant.

Even with rape, section 14 of the Criminal Offences Act, 1960, makes it clear that consent is only valid in criminal law if it is given freely and with full understanding. Consent is void where the person is under 12 years of age (or under 16 in sexual offenses), insane, immature, intoxicated, or otherwise incapable of understanding. It is also void if obtained by deceit, duress, undue exercise of authority given by a parent or guardian not in good faith, based on a fundamental mistake of fact, or would not have been given but for such deceit, duress, authority, or mistake. Authority includes not only commands but also influence or advice given by virtue of authority, though a person will not be prejudiced by invalid consent if he neither knew nor could reasonably have known of its invalidity. A young person who acts on such misconceptions risks severe criminal liability, including long-term imprisonment. Similar misunderstandings exist with offenses such as theft, fraud, and assault, where popular assumptions often diverge sharply from statutory definitions. The absence of structured education in criminal law therefore places many Ghanaians, especially the youth, in danger of unknowingly engaging in criminal conduct.

The problem lies in an educational gap. Ghana’s curriculum at the secondary and tertiary levels prioritizes mathematics, science, and literature, but largely neglects law, particularly criminal law. Students graduate from senior high school, and even from universities, without foundational knowledge of what constitutes a crime, the rights of the accused, or the duties of citizens under the law. Yet, criminal law is not an abstract field reserved for lawyers; it is the branch of law that most directly governs daily behaviour. Unlike specialized fields such as commercial, company, or contract law, criminal law affects every citizen’s life, regardless of profession or social status. The paradox is striking: the state demands universal compliance with criminal law while failing to provide its citizens with the educational tools necessary to understand it. In this sense, the principle that ignorance of the law is no excuse risks functioning less as a principle of justice and more as a trap for the uninformed.

The way forward is to deliberately embed criminal law into the formal curriculum at both secondary and tertiary levels. The question then arises as to which aspects of criminal law must be taught, given that almost every piece of legislation in this country has some criminal law aspect. For instance, the Representation of the People Law, 1992 (PNDCL 284), in Sections 27-40, creates offenses in relation to the regulation of elections. Since all these laws cannot be taught in schools, at least the major offenses stated in the Criminal Offences Act, 1960 (Act 29), must be taught.

At the high school level, a compulsory subject introducing students to the core principles of criminal liability and the major offenses under Act 29 would provide a basic

At the university level, irrespective of discipline, students could be required to take a general course in criminal law designed not to train lawyers, but to ensure that graduates in every field have a foundational competence in the rules of the criminal justice system. The benefits of such reforms would be significant. A population educated in criminal law is less likely to commit offenses out of ignorance, and more capable of protecting itself against abuse, exploitation, and arbitrary state action. Knowledge of criminal procedure and constitutional rights would empower citizens to defend themselves in encounters with law enforcement, thereby strengthening accountability and the rule of law.

At the same time, civic responsibility would be fostered, as individuals gain a clearer understanding of the boundaries of lawful conduct and the duties they owe to society. In the long term, a legally literate population would reduce the frequency of offenses based on ignorance and ease the burden on courts and correctional facilities. Criminal law is the most immediate and consequential branch of law for ordinary citizens, yet it remains conspicuously absent from Ghana’s educational system. If the principle that ignorance of the law is no excuse is to be applied fairly, then the state must provide its citizens with the opportunity to know the law they are expected to obey.

Incorporating criminal law into the curriculum from high school through to the university is not about professional legal training. It is about equipping citizens with the knowledge necessary to live responsibly, protect themselves, and contribute to a just society. In this way, legal literacy would cease to be a privilege of the few and become a foundation for justice, democracy, and social progress. Ignorance of the law may not excuse anyone, but equipping young people with knowledge of the law can protect everyone, since criminal law is for the protection of the individual, and not a trap for the unwary.
