This summary is not the rule. The rule text controls.
These procedural rules don't change which court can hear your case or where you can file it. Jurisdiction (which courts have the power to decide a case) and venue (which location is the right place to file) are set by other laws, not by these rules of procedure.
In simple terms, this rule just makes sure everyone understands what these rules are for. They explain how a case moves through court once it's filed in the right place. They are not meant to give a court new power to hear a case it normally couldn't, and they're not meant to take away power a court already has. The same goes for venue: these rules don't change where a lawsuit is supposed to be filed.
This matters because people sometimes confuse procedural rules with the laws that actually decide where a case belongs. If you have questions about whether a specific court can hear your case, or whether you filed in the correct location, you need to look at the separate statutes and rules that specifically cover jurisdiction and venue, not this set of procedural rules.
