Common questions
Frequently Asked
3
When does Hanna Part I require a federal court to apply a Federal Rule of Civil Procedure over a conflicting state rule?+
Hanna Part I requires application of the federal rule whenever a valid Federal Rule of Civil Procedure is directly on point. The rule must be at least arguably procedural and within the scope of the Rules Enabling Act. State law yields even if the outcome differs.
Supporting sources
How does Hanna Part I differ from the forum-shopping analysis in Hanna?+
Hanna Part I applies when a Federal Rule of Civil Procedure is on point and valid. The forum-shopping test applies only when no federal directive governs the issue. The two inquiries are sequential.
Supporting sources
Does Hanna Part I apply to state rules that affect substantive rights?+
No. If the federal rule would abridge, enlarge, or modify a substantive right, it falls outside the Rules Enabling Act and Hanna Part I does not authorize its application. The rule must remain procedural in character.
