ZF Automotive U. S., Inc. v. Luxshare, Ltd.
The Supreme Court unanimously ruled that the federal law allowing U.S. courts to help gather evidence for use in 'foreign or international tribunals' applies only to governmental or intergovernmental bodies — not private arbitration panels, even when an arbitration arises from an international treaty between two countries.
The decision resolves a long-running disagreement among federal appeals courts and means that parties in foreign private arbitrations can no longer use U.S. courts to compel American witnesses and businesses to produce documents or testimony under this powerful evidence-gathering law.
How it got here: Federal district courts in Michigan and New York both granted §1782 evidence requests; the Supreme Court took the first case before the Sixth Circuit ruled and the second after the Second Circuit affirmed.
The Case in Depth
What happened
Two separate disputes reached the Court together. In the first, a Hong Kong company (Luxshare) alleged it was defrauded in a nearly billion-dollar deal to buy business units from a Michigan auto-parts maker (ZF Automotive), and sought evidence from ZF for a pending German private arbitration. In the second, a Russian investment fund claimed Lithuania illegally seized assets from a failed Lithuanian bank and sought evidence from a New York consulting firm for an investor-state arbitration under a Russia-Lithuania treaty. Both sought evidence under a federal law meant to assist foreign proceedings.
The question before the Court
Can parties to a private foreign arbitration use a U.S. federal law to force American companies or individuals to hand over evidence for use in that arbitration?
The Court's answer
No — the federal law at issue (28 U.S.C. §1782), which lets U.S. district courts order evidence for use in a "foreign or international tribunal," covers only governmental or intergovernmental bodies. Private arbitration panels do not qualify, regardless of how large or sophisticated the dispute.
The private German arbitration panel (DIS) in the first case was created by a private contract with no government involvement in its formation or rules — clearly outside the law's reach. The ad hoc panel under the Russia-Lithuania investment treaty in the second case was harder: a sovereign government was a party and the arbitration came from a treaty. But the Court found Russia and Lithuania did not intend to vest that panel with governmental authority. Its authority came from the parties' consent to arbitrate, not from any grant of sovereign power — making it, in substance, no different from any other private arbitration.

Why it matters
Companies and individuals caught up in international private arbitrations — the standard forum for resolving billion-dollar cross-border business disputes — can no longer use U.S. federal courts to compel American witnesses or companies to hand over documents and testimony. They are limited to whatever, typically much narrower, discovery tools the arbitration rules themselves provide.
What changes now
Both discovery orders are reversed, meaning ZF Automotive and AlixPartners do not have to produce evidence under §1782. Luxshare and the Fund must pursue whatever discovery tools are available under the rules of their respective arbitrations. Going forward, parties in foreign private arbitrations — including investor-state arbitrations under investment treaties — cannot use §1782 to compel American witnesses or companies to produce evidence, resolving the circuit split that had produced conflicting results across the country.
What this does not decide
The Court does not decide that a sovereign-created ad hoc arbitration panel can never qualify as an intergovernmental tribunal — only that the panels in these specific cases do not. Nations could, in principle, draft a treaty that clearly vests an ad hoc panel with governmental authority. The Court also leaves open the precise outer bounds of what kinds of quasi-judicial bodies do qualify.
How the Court got there
The legal reasoning, step by step
- The Court began with the statute's key phrase: 'foreign or international tribunal.' The word 'tribunal' alone could mean any adjudicatory body, but context narrows it. When 'foreign' modifies a word that carries governmental or sovereign overtones — like 'tribunal' — it naturally means belonging to a foreign nation, not merely located in one. Belonging to a nation requires that the nation confer sovereign authority on the body.
- The statute's own procedural defaults reinforce this reading. Section 1782 says district courts may apply the 'practice and procedure of the foreign country or the international tribunal.' That phrasing presumes a foreign tribunal follows rules set by a country's government — an odd assumption for a private body whose rules are set by private parties in a contract.
- The statute's history points the same way. From 1855 to 1964, §1782 covered only foreign courts. When Congress expanded it in 1964, it tasked the Commission that drafted the revision with improving assistance to 'foreign courts and quasi-judicial agencies' — governmental bodies. The 1964 expansion broadened which public bodies were covered, not whether private bodies counted at all. The animating goal was international comity: helping foreign governments, not private parties.
- Extending §1782 to private arbitration would create a glaring mismatch with the Federal Arbitration Act (FAA), which governs domestic arbitrations and allows far more limited discovery. Under the FAA, only the arbitration panel itself can request evidence from courts, and pre-arbitration discovery is unavailable. Giving parties in foreign private arbitrations broader U.S.-court discovery than parties in domestic arbitrations have would be an anomaly with no clear rationale.
- Applying these rules: the DIS panel in the ZF/Luxshare dispute was formed by a private contract between private companies with no government involvement — it fails the test straightforwardly. The ad hoc UNCITRAL panel under the Russia-Lithuania investment treaty presents a closer call because a sovereign is a party and the arbitration option appears in a treaty, but neither fact is decisive. What matters is whether Russia and Lithuania intended to clothe that panel with governmental authority — and they did not. The panel was not pre-existing, received no government funding, and operated independently of both nations. Its authority came from the parties' consent to arbitrate, not from any sovereign grant.
