Lainoppi

Lainoppi is a Finnish term for the science or doctrine of law, i.e., jurisprudence. The word combines laki (law) with oppi (doctrine or teaching) and is used to denote the theoretical and systematic study of legal concepts, norms, and reasoning. In this sense, lainoppi refers to the doctrinal framework underlying a legal order rather than to individual laws.

The scope of lainoppi includes the analysis of legal principles, interpretation of statutes, and the methods by which legal norms are derived, applied, and justified. It encompasses questions of sources of law (such as statutes, regulations, and case law), legal theory, doctrinal practice, and the coherence of the legal system. It is closely connected to concepts like legal reasoning, normative justification, and jurisprudential debates about how law ought to be understood and applied.

Historically, lainoppi has been used within Finnish legal scholarship to describe the doctrinal side of oikeustiede, the broader field of legal science. It was commonly taught in Finnish law faculties during the 19th and early 20th centuries as the philosophical and methodical core of legal education, alongside the study of statutes and case law.

In contemporary usage, the term lainoppi is less common in everyday language. Modern Finnish legal literature typically uses oikeustiede, jurisprudence, or doctrinal analysis to describe the same or similar ideas. When encountered, lainoppi is usually present in historical texts or in discussions of the development of Finnish legal theory.
