What is the basic aim of the Erie doctrine in diversity cases?

• A. To require federal courts to apply federal substantive law.
• B. To maintain uniform outcomes by applying state substantive law and federal procedural rules.
• C. To prohibit federal courts from sitting in diversity.
• D. To require state courts to apply federal procedural rules.

Answer: (B)

The main idea behind Erie in diversity cases is to prevent a federal court from applying its own set of substantive rules to a state claim, while still letting federal procedural rules govern how the case is fought in court. In diversity situations, federal courts must use state substantive law to determine elements of the claim, defenses, statutes of limitations, and other substantive issues, but they apply the Federal Rules of Civil Procedure for how the case is adjudicated. This approach aims to avoid inequitable results and forum shopping, by ensuring that the substantive rights and obligations come from the state where the dispute arose, not from federal-law preferences, while keeping the procedural process uniform under federal control. So the best choice captures both pieces: state substantive law for what the rights are, and federal procedural rules for how the case proceeds. The other statements misstate the doctrine: federal courts do sit in diversity, and they do apply federal procedural rules in that setting; ERIE does not require state courts to apply federal procedural rules.
