Non Sequitur Law and Legal Definition

Non sequitur is a Latin term meaning "it does not follow", usually referring to drawing a conclusion after logical reasoning, or that a conclusion does not logically follow from the facts or law. It is when an action or event does not relate back to preceding events. It may refer to fallacies in which one or more premises are irrelevant to an inference, and the inference is in fact arbitrary. Principles of common law (tort negligence theories) and of a key statute in state law require reasonableness. While legal criteria for reasonableness are relatively imprecise in law and tend to be collected through a body of case law precedents, the key point is the word "reason": Can the conclusion be inferred from its premises?
