Whether § 8772 violated Article III and the separation of powers by changing the law governing a pending enforcement proceeding in a manner that favored the terrorism judgment creditors.
Holding
No. Congress may amend substantive law and make the amendment applicable to pending civil cases, even when the amended law is outcome determinative.
Reasoning
Article III prevents Congress from exercising the judicial function: Congress may not tell courts how to apply old law to a particular set of facts, require them to act unconstitutionally, subject their judgments to executive revision, or order them to reopen final judgments. But those limits do not prevent Congress from changing the governing law and requiring courts to apply the new law in cases that have not reached final judgment.
United States v. Klein did not establish a broad ban on legislation affecting pending cases. In Klein, Congress attempted to dictate a result without validly changing the legal effect of a presidential pardon, a subject on which Congress lacked authority to override the President. Later decisions, especially Robertson v. Seattle Audubon Society and Plaut v. Spendthrift Farm, distinguish an impermissible command to reach a result under old law from a permissible amendment of the law itself.
Section 8772 supplied new substantive standards for execution against the identified assets. It made certain Iranian assets subject to execution notwithstanding otherwise applicable sovereign-immunity and state-law barriers, while still requiring the District Court to determine whether the assets were held in the United States, were blocked, corresponded in value to Iranian assets, belonged beneficially or equitably to Iran, and were free of any other person’s constitutionally protected interest.
The fact that the statutory predicates may have pointed strongly toward one result did not convert the statute into a judicial command. A court still exercises judicial power when it applies a new legal rule to facts, even if the relevant facts are undisputed and the result is effectively clear. The Court compared this ordinary judicial task to applying a new treaty or statute that leaves only one lawful disposition of the case.
