Greiner Civil Procedure Version 02

Smith v. Kansas City Title & Trust Co., 255 U.S. 180 (1921)

Mottley stated the general rule regarding arising under jurisdiction:  federal district court subject matter jurisdiction exists under Section 1331 only if the plaintiff asserts a federally created cause of action.  That rule governs perhaps 99.9% of arising under cases in federal court.  One exception to this rule is referred to as the "Smith-Grable" exception, after the two cases that gave rise to it.  If you become a federal court litigator, you may never see the Smith-Grable exception used.  But learning about it teaches a lot about why we have federal courts.  Smith appears below.
