Rethinking the maxim ignorantia juris non excusat

The proliferation of criminal laws in different legal systems has made legal practitioners and scholars deliberate upon the present day relevance of old age principles and concepts. The maxim ignorantia juris non excusat (ignorantia juris hereinafter) also falls in this category. The application of criminal law is said to rest on the maxim ignorantia juris, meaning ignorance of law is no excuse. The application of the maxim has from time immemorial been defended on grounds of convenience, utility, and community interests. At the same time it has been challenged on grounds of legality and morality. The application of the maximin criminal matters is secured through penal laws. These laws are further validated through judicial pronouncements. Penal statutes and judicial pronouncements have largely been the basis to determine the exceptions and scope of the maxim. Breaking it down to a single case in hand, several factors come into picture including the nature of the crime in question, the mental state of the person accused, the conduct of the accused person, the objective or public utility of the criminal legislation or provision, and the reasons or justifications offered for its rigid or qualified application. The single case is viewed in light of the general provisions of criminal law of the legal system in which the case is being tried. The uniqueness of each case and the criminal statutes of legal systems make it both complex and conducive to generalize or conclude on the true import and application of the maxim ignorantia juris
