Here's a plain English summary of this rule:
The rules that govern how court cases are handled don't change which courts have the power to hear a case. They also don't change where a case can be filed. In other words, these procedural rules only control the steps and process of a lawsuit, not whether a particular court is allowed to take the case in the first place.
Think of it this way: the rules tell you how to fight your case in court, but they don't decide which courtroom you're allowed to fight it in. That decision depends on other laws that set out jurisdiction (which courts have authority) and venue (which location is proper for the case). This rule simply makes clear that nothing in the civil procedure rules can be used to argue that a court has more or less power than the law already gives it, or that a case belongs in a different location than the law already says.
