A situation arising in choice-of-law analysis when the laws of states with relevant contacts to a dispute differ on the specific issue to be decided. When states share identical local rules on that issue, the contacts may be treated as if located in a single state applying the common rule, avoiding further conflict analysis.

How it applies
Common Examples
6
Contract Noncompete Choice-of-Law Dispute
Acme Corp in State A sues a former employee now living in State B over a noncompete clause. State A law enforces the clause while State B law voids it. Because the differing rules on the precise issue create a real conflict, the court must select which state's law governs under modern choice-of-law principles.
Class Action Bar in Diversity Suit
A medical provider files a class action in federal court under diversity jurisdiction. The state statute bars certain class claims, but the federal rule directly addresses class certification. Because the federal rule controls, no real conflict arises that would require applying the state bar.

Preemption of State Tort Claims
A driver injured in a car accident sues the manufacturer under state tort law for failing to install airbags. Federal safety standards permit manufacturers to choose among restraint options. The state claim creates a real conflict with the federal regime and is preempted.
Geier v. American Honda Motor Co.529 U.S. 861, 874–75 (2000)
Interspousal Immunity Choice of Law
A wife sues her husband for injuries sustained in an accident that occurred in another state. The forum applies its own law on interspousal suits rather than the place-of-injury rule. The differing rules produce a real conflict that the court must resolve under modern choice-of-law principles.
A patient sues a device manufacturer under state negligence and strict liability theories. Federal regulations set specific requirements for the device. Because the state claims impose additional duties, a real conflict exists and the federal requirements preempt the state claims.
Medtronic, Inc. v. Lohr518 U.S. 470, 485 (1996)
Class Action Settlement Approval
A class of out-of-state plaintiffs settles a securities claim in the forum state. The forum applies its own procedural rules to approve the settlement. Because other states' laws on class notice and opt-out rights are identical, no real conflict arises and the forum may treat all contacts under its common rule.

Common questions
Frequently Asked
3
When do identical state rules eliminate a real conflict in choice-of-law analysis?+
When states sharing contacts have identical local rules on the precise issue, the multistate contacts may be treated as if located in a single state applying that common rule. This avoids unnecessary conflict analysis among the forum and other states.
Supporting sources
Does a federal rule always displace a conflicting state rule in diversity cases?+
A valid Federal Rule of Civil Procedure that directly addresses the issue governs even if a conflicting state rule would produce a different outcome, provided the federal rule is procedural and within the Rules Enabling Act.
Supporting sources
How does the absence of a real conflict affect preemption analysis?+
When state and federal requirements can operate together without actual inconsistency, courts avoid finding preemption. A real conflict must exist before state law yields under the Supremacy Clause.
