Morphology

case + law

The meaning 'law derived from judicial decisions' is directly and transparently built from 'case' (a court matter) + 'law' (rules or statutes); a learner who knows both constituents can infer it refers to law coming from court cases rather than written statutes. This compounding follows common cross-linguistic patterns (many languages have an equivalent term), so a B1 learner would generally grasp the concept even if they lack detailed legal knowledge.

Etymology

Case law comes from the idea of rules made from individual cases, or past court decisions, rather than from written laws. When a judge decides a case, that decision can be used as an example for later cases, so many decisions together form the 'law' we call case law.
