Blended Speech Analysis Triggers Review
Horizon Wireless challenged a state fine for data throttling in state court under both the state constitution and federal speech protections. The state supreme court affirmed in a single discussion that treated the state and federal provisions as coextensive without declaring the state ground independent. Horizon petitions the Supreme Court. The Court presumes jurisdiction because the opinion contains no clear statement that the judgment rests solely on independent state law.
Alimony Statute Challenge Reaches Court
William Orr contested an alimony award under a state statute that treated spouses differently by sex. The state court rejected his equal protection claim after considering both state family law rules and federal constitutional standards in one analysis. Orr seeks Supreme Court review. The Court exercises jurisdiction because the state opinion never expressly rested the judgment on independent state grounds alone.

Common questions
Frequently Asked
4
When does the Supreme Court presume it has jurisdiction over a state court judgment?+
The Supreme Court presumes jurisdiction when a state court opinion discusses state and federal law in a blended way and does not clearly and expressly state that the judgment rests on independent state grounds. This presumption treats the decision as resting on federal law so that review remains available.
Supporting sources
What must a state court do to insulate its decision from Supreme Court review?+
A state court must clearly and expressly state that its judgment rests on state-law grounds independent of federal law. Mere citation of state constitutional provisions or a blended analysis is insufficient to defeat jurisdiction.
Supporting sources
Does mentioning federal precedent automatically create Supreme Court jurisdiction?+
No. Jurisdiction turns on whether the state court clearly and expressly rested its judgment on independent state grounds. A passing reference to federal law does not create jurisdiction if the opinion expressly disclaims reliance on federal law.
Supporting sources
What happens when a state court opinion alternates between state and federal analysis?+
The Supreme Court applies the presumption of jurisdiction because the opinion is ambiguous. The state court must make an express statement of independence to overcome the presumption.
