A choice-of-law consideration that favors rules producing uniform outcomes across forums. It protects parties' justified expectations by allowing them to plan transactions with reference to a predictable body of law.
Atlas Capital purchased secured loans backed by artwork stored in State B. After BullionSafe entered receivership, local creditors challenged Atlas's priority. The court selected the law of the state with the most significant relationship, producing the same priority ranking no matter which forum heard the case and allowing future lenders to structure deals with certainty.
Hartford Fire Insurance faced antitrust claims from multiple states over reinsurance practices. The Supreme Court applied a single federal standard rather than varying state rules.

Pacific Mutual Life Insurance faced a bad-faith claim in Alabama. The Court upheld a punitive award under a clear state standard that other forums could replicate. Insurers could therefore forecast exposure when issuing policies nationwide rather than facing unpredictable multipliers depending on the plaintiff's chosen court.
Allstate Insurance litigated coverage after a fatal accident involving a policyholder who had moved between states. The Court selected Minnesota law because it had the most significant relationship. This produced a consistent coverage result that matched the parties' planning expectations regardless of where suit was filed.
Daimler AG faced claims in California over events occurring abroad. The Court limited general jurisdiction to the company's home states. Corporations could therefore anticipate exactly which courts could hear claims against them, enabling reliable risk assessment when structuring global operations.
Hertz Corporation was sued in California by employees who lived there. The Court held that a corporation's principal place of business is its nerve center. This bright-line rule let companies know in advance which state's courts would treat them as citizens, removing uncertainty from diversity jurisdiction planning.

No. Courts may apply different states' laws to different issues within one case when each issue has its own most significant relationship. The goal remains consistent, foreseeable results for the parties' planning.
