Whether the Eleventh Amendment bars the plaintiffs' claims seeking restoration of the lost school-land trust corpus, replacement lands, past income, or continuing payments equivalent to income from the lost corpus.
Holding
Yes. The trust-based claims are barred because, in substance, they seek retrospective monetary relief for an alleged past breach by the State.
Reasoning
Under Ex parte Young, federal courts may enjoin state officials to end an ongoing violation of federal law, even if compliance has an incidental financial effect on the state treasury. But the Eleventh Amendment prohibits relief that is effectively compensation for a past violation, regardless of whether the requested remedy is labeled damages, restitution, an injunction, or continuing income.
The plaintiffs characterized Mississippi's duty as a continuing federal trust obligation: because the State had lost the corpus, it allegedly remained obligated to provide the income that the corpus would have generated. The Court held that this characterization did not alter the substance of the claim. Requiring the State to replace the corpus or pay its equivalent income would impose an accrued monetary liability arising from the nineteenth-century sale and loss of the lands.
The Court assumed, without deciding, that the federal grants created an enforceable trust. Even on that assumption, an unextinguished liability for an earlier breach of trust is not the same as a present violation that may be remedied prospectively under Ex parte Young. The plaintiffs' related Contract Clause claim failed for the same Eleventh Amendment reason.
