The legislative history to 28 U.S.C. § 1367(b)indicates the intent to prohibit supplemental jurisdiction when its exercise would circumvent traditional330limitations on the grant of diversity jurisdiction.

(a) P, from Virginia, sues D, from Texas, and D files an impleader complaint against TP from Texas;

(b) P from Virginia, sues D, from Texas, and D files an impleader complaint against TP from Virginia;

(c) Assuming the facts of (b), P then asserts a state law claim against TP from Virginia.
