Precedent

A previous court decision that may guide or bind later cases.

What it means

A precedent is a previous court decision that may matter in a later legal question. It matters because of the legal rule the court decided, the court level, the facts, and whether later law changed it.

Why it matters at work

In legal research, a precedent is not useful just because it sounds similar. You need the case, court, date, paragraph, exact point, and whether it is binding or persuasive.

Beginner mistake

Writing “legal presidents” or trusting a case name from AI without opening the judgment and checking the paragraph.

Example prompt

Using only this judgment excerpt, identify the legal point decided, the paragraph that supports it, and whether the point needs lawyer verification.
