Rule 47 simply gives this set of rules its official name: the Tennessee Rules of Appellate Procedure. When you see this name used in court documents, legal briefs, or other filings, it refers to this specific set of rules.
This rule doesn't create any rights, deadlines, or procedures on its own. It just establishes the official title so that courts, lawyers, and other people can refer to these rules consistently and know exactly which set of rules they're talking about.
