How it applies
Common Examples

Service on Corporate Defendant
Alex served Regional Bank by delivering the summons to a branch manager. State law required service only on the bank's designated statutory agent. The court applied the federal service rule because it was valid under the Enabling Act and therefore governed the procedural question in the diversity action.
Class Certification for Interest Claims
Maria sought to certify a class of tenants claiming unpaid deposit interest from UrbanGate. A state statute barred representative actions for such claims. The court applied Rule 23 because the rule was valid under the Enabling Act and controlled the availability of class treatment despite the conflicting state provision.

Common questions
Frequently Asked
4
When does a Federal Rule of Civil Procedure displace a conflicting state rule in diversity cases?+
A Federal Rule controls if it is on point and valid under the Rules Enabling Act. Validity requires that the rule regulate procedure without abridging, enlarging, or modifying any substantive right.
Supporting sources
Does Rule 23 remain valid when a state statute bars class actions for certain claims?+
Yes. Rule 23 governs class certification because it addresses only the procedural mechanism for aggregation and does not alter the underlying substantive rights to recover.
Supporting sources
What test determines whether a federal rule is valid under the Rules Enabling Act?+
The rule must deal with practice or procedure and must not abridge, enlarge, or modify any substantive right. Rules meeting this standard apply in diversity actions even when they conflict with state law.
Supporting sources
How does the Enabling Act interact with the twin aims of Erie?+
When a valid Federal Rule is on point, the Enabling Act analysis controls and the forum-shopping inquiry applies only in the absence of such a rule.
