This lesson introduces obiter dictum and distinguishes it from the binding core of a judicial decision. Understanding the distinction matters because it helps explain which statements courts must follow as precedent and which may only persuade them.
The Latin phrase obiter dictum means “said in passing.” Its plural is obiter dicta; lawyers also often use the shorter terms dicta or obiter. The concept comes from English common law, where a judgment is understood to include two kinds of judicial statements: the ratio decidendi and obiter dicta.
