Law360, New York (May 03, 2011, 1:19 PM ET) -- New products are constantly being developed to meet modern needs and expectations. The law evolves to regulate the development, marketing and use of these products. Tort law governs claims for damages. This yields decisional law, referred to as case precedent. Whereas legislative enactments produce a distillation of a broad consensus, case precedent comes from individualized, interpretive applications of law to facts. Each such precedent is then either applied or rejected in subsequent cases, producing a body of decisions known as the common law.
