Each personal injury has unique case law that accompanies it. “Case law” refers to the law that judges make over time. Consider an automobile accident case. Over the years, various plaintiffs have brought motor vehicle personal injury lawsuits to Court. Each case turned out slightly differently, depending on the factual scenario unique to that case. The ruling that the judge makes in a case has a binding effect, to some extent, in future cases that other judges hear in that area of law (depending on the level of court and jurisdiction).
