In a transnational legal standoff with billions in global investment implications, the U.S. Supreme Court on Monday asked the Solicitor General to weigh in on Spain’s petition challenging a lower court decision that paved the way for enforcing $419.45 million in arbitration awards against the European nation.
The move signals the high court’s growing focus on how far U.S. courts can go in enforcing arbitral awards against foreign sovereigns — a flashpoint that could reshape the balance between national immunity and investor rights.
Spain’s $419M Question Lands Before the Justices
Spain’s petition targets a D.C. Circuit ruling that upheld enforcement of a combined €331 million ($386.84 million) in arbitral awards in favor of NextEra Energy Inc. and 9REN Holdings SARL, both energy investors who claim Spain unlawfully upended renewable energy incentives.
The case also involves a €26.5 million award to AES Solar Energy Coöperatief UA and Ampere Equity Fund BV, later assigned to Blasket Renewable Investments LLC, bringing the total at stake to roughly $419.45 million.
Spain argues the ruling opens dangerous new legal territory — one where foreign sovereigns could be hauled into U.S. courts without first confirming they ever consented to arbitration.
