A state-law basis for a judgment that is sufficient by itself to support the result reached. The basis must stand apart from federal law so that a federal court decision on the federal question would not alter the outcome.
Horizon Wireless challenged a state fine for data throttling. The state supreme court upheld the fine after discussing both the state free-speech clause and federal speech doctrines in a single analysis without declaring that state law alone controlled. The U.S. Supreme Court presumes jurisdiction because the opinion supplies no clear statement of an independent state ground.
Adrian Aguilar raised a federal constitutional objection to evidence admitted at trial. The state appellate court rejected the claim solely because Aguilar failed to comply with a state contemporaneous-objection rule. A federal habeas court treats the procedural default as an adequate state ground that blocks merits review.

Arthur Abrams contested personal jurisdiction in a state probate proceeding. The state high court dismissed the action after citing both state long-arm precedents and federal due-process standards without separating the two analyses. The U.S. Supreme Court treats the decision as resting on federal law absent an express independent state ground.
Angela Acosta sought post-conviction relief based on newly discovered evidence. The state court denied relief under a state rule requiring claims to be raised within a fixed time after finality. The adequate state ground prevents federal habeas review even though the underlying claim implicates federal constitutional rights.
Alexis Archer appealed a criminal conviction but could not afford the required transcript. The state court dismissed the appeal for failure to comply with a state rule mandating prepayment. The dismissal rests on an adequate state ground that precludes Supreme Court review of the federal equal-protection claim.
Ariana Azizi invoked her right to remain silent during custodial interrogation. The state court admitted later statements after applying a state evidentiary rule on re-initiation of questioning. Because the ruling rests on that independent state ground, the U.S. Supreme Court lacks jurisdiction to review the federal self-incrimination claim.
The Court presumes jurisdiction when the state opinion does not clearly and expressly state that the judgment rests on state-law grounds independent of federal law. The state court must supply an unambiguous declaration that its holding is supported by adequate and independent state grounds before the presumption is overcome.
Supporting sources
The Supreme Court treats the decision as resting on federal law and exercises appellate jurisdiction. A blended discussion that never declares the state clause alone sufficient fails the clear-statement requirement and keeps the case within federal review.
Supporting sources
No. A state court must clearly and expressly rely on state law as a separate basis for its decision. Simply referencing state provisions while treating them as coextensive with federal law does not satisfy the independence requirement.
Supporting sources
State courts bear the burden of making independence explicit. Without a plain statement that the judgment rests on state law independent of federal law, the Supreme Court will presume jurisdiction and proceed to the merits of the federal question.
