Rule 82.Jurisdiction Unaffected

Rule 82 does one job in a single sentence: the civil rules do not extend or limit the jurisdiction of the Superior Court. Jurisdiction — the court's underlying authority to hear a particular kind of case at all — comes from the District of Columbia Code and other statutory sources, not from a procedural rulebook. A rule that tells parties how to plead, serve, or try a case cannot be read to hand the court power over subject matter it otherwise lacks, and it equally cannot be read to take away power the court already has.

That separation matters in practice. A party cannot argue that some procedural mechanism in the civil rules — a joinder provision, a counterclaim rule, a venue-adjacent filing requirement — somehow gives the court authority over a claim or a party it could not otherwise reach. The reverse is also true: a gap or limitation in the rules is not itself a jurisdictional limitation. Whether the Superior Court can hear a case is a question the jurisdictional statutes answer; Rule 82 only confirms that the rules never enter that analysis.

The District of Columbia version of this rule is narrower than some counterparts elsewhere, because it drops language about venue and about admiralty and maritime claims that has no application in a single, local trial court like the Superior Court. What remains is the core principle, stripped down to its essentials: rules of procedure and rules of jurisdiction operate on entirely different axes, and Rule 82 keeps them from being confused with one another.
