This summary is not the rule. The rule text controls.
This part of the law simply gives the rules their official name. It says these rules are called the Tennessee Rules of Criminal Procedure.
It also explains how people should refer to them in writing, like in court documents or legal papers. The short form used for this is "Tenn. R. Crim. P." This makes it easier for lawyers, judges, and others to point to these rules quickly without writing out the full name every time.
There's nothing more to this section beyond naming and labeling the rules. It doesn't set any actual legal requirements or procedures for criminal cases in Tennessee.
