In 2005, Congress passed the Class Action Fairness Act (CAFA), which gave federal courts jurisdiction over class actions with both minimal diversity and an amount in controversy exceeding $5 million. In the wake of CAFA, federal courts have struggled to formulate appropriate standards of proof when the defendant removes a class action to federal court and the plaintiff seeks to remand the case to state court. This Note argues that if a defendant looks to remove such a class action, it should have to demonstrate that the amount in controversy is met by a preponderance of the evidence—regardless of whether the plaintiff’s complaint requests a specific amount of damages. In addition, if a plaintiff wants to utilize either of CAFA’s “federalism exceptions” to federal jurisdiction, it should have the benefit of a rebuttable presumption that a class member’s state of residence is her state of citizenship. This two-part approach comes closest to effectuating the “balanced diversity” that Congress intended in CAFA.
