§ 1145.1 Short title.

This rule simply gives an official name to a group of related laws. That name is "The Uniform Disposition of Criminal Cases on the Merits Act." When other parts of the law refer to this act by name, they are talking about this same set of rules.

Think of this like a title on a book. It doesn't set out any actual legal requirements by itself. Instead, it tells you what to call the broader set of rules that follow, so people can refer to them easily and know which laws they're talking about.
