A matter of Jurisdiction (Subject)

[Verse 1] Before you file your case In federal court's embrace There's something you should know About the rules that make it so Two paths you can pursue Let me explain them both to you [Chorus] Federal subject matter jurisdiction Gotta have it or your case won't run Either federal question within Or complete diversity must be won Oh, let me tell you more...
