Perusratkaisusta

Perusratkaisusta is the genitive form of perusratkaisu, a Finnish legal term used to refer to the base or leading decision in a court ruling. In Finnish jurisprudence, perusratkaisu denotes a fundamental decision that establishes central legal principles, interpreting standards, or a framework that guides subsequent cases.

The term is not a formal procedural category, but a descriptive label found in legal literature and case commentary. It emphasizes the core reasoning and normative approach laid down by a court, rather than every detail of the judgment. When lawyers and scholars discuss a decision, they may refer to what follows from the perusratkaisusta—that is, the principles or interpretations that the ruling sets forth as a basis for future analysis.

Perusratkaisusta often appears in discussions of precedent and jurisprudence. A landmark or foundational ruling can function as a perusratkaisu because it provides a reference point for later decisions on similar issues. In this sense, the concept is closely related to, but distinct from, the broader concept of ennakkotapa (precedent). The description of a perusratkaisusta can help readers understand how a decision shapes legal interpretation and application.

In practice, the use of perusratkaisu is common in constitutional, administrative, and civil law discussions, where courts articulate essential principles that guide future rulings. The phrase “perusratkaisusta” is used to discuss what the base decision establishes, including the central arguments, tests, or standards it introduces.
