What is the appropriate term for a detailed explanation or interpretation within a legal framework?

The term that refers to a detailed explanation or interpretation within a legal framework is typically "directive." Directives are authoritative instructions or orders that provide specific guidance on how laws or regulations should be interpreted and applied. They may be issued by governmental bodies or agencies and aid in clarifying the intentions behind statutory laws, thus ensuring consistent interpretation across different jurisdictions or situations.

On the other hand, a writ is a formal order issued by a court, a statute is a written law enacted by a legislative body, and a codex refers to a collection of laws or legal codes. While each of these terms has its own significance within the legal system, they do not specifically convey the idea of providing a detailed explanation or interpretation as effectively as a directive does.
