The integration of Artificial Intelligence (AI) technologies is fundamentally reshaping the legal profession, presenting both unprecedented opportunities for efficiency and innovation, and profound ethical and professional challenges. This article argues that the imperative for robust AI ethics must be conscientiously integrated into legal education, particularly within vocational institutions like the Nigerian Law School (NLS). Drawing on an analysis of AI’s role, history, and defining characteristics, the article identifies critical ethical sustainability challenges, including algorithmic bias, data privacy breaches, challenges to academic integrity (such as plagiarism and unauthorized content generation), and the critical issue of accountability for AI-generated legal errors. The article proposes that legal education must shift its focus from preventing AI use to teaching responsible, ethical use, equipping future practitioners with the requisite technical literacy, critical thinking, and human judgment necessary to mitigate risks and uphold core professional duties, such as competence, integrity, and the duty not to mislead the court. Ultimately, fostering a culture of ethical and responsible AI engagement is essential to ensure the long-term viability and integrity of the legal profession in the digital age.
