Moore v. Harper [2023]
600 U.S. ___ (2023) · Supreme Court of the United States · United States
Issue
Does the Elections Clause vest exclusive, non-reviewable authority in state legislatures to regulate congressional elections, such that state courts cannot enforce state constitutional limits on that authority (the 'independent state legislature theory')?
Held
No. The Elections Clause does not insulate state legislatures from ordinary state constitutional constraints. State courts may review election laws under state constitutions, subject to the usual rule that the ultimate interpretation of state law is a matter for state courts.
Exam use
Moore v. Harper is best used to analyze the allocation of power over federal elections. On an exam, if a state legislature argues that it can ignore a state constitutional provision (like a requirement for compact districts or an anti-gerrymandering amendment) when drawing congressional maps, cite Moore for the proposition that the legislature is subject to those state constitutional limits. Also use it to discuss the role of state courts in reviewing election laws after Rucho. The case also limits the reach of federal courts: the Supreme Court will not ordinarily second-guess a state court's interpretation of its own constitution in an election case, absent a federal constitutional issue.
Summary
The Supreme Court rejected the 'independent state legislature theory' that would have given state legislatures nearly exclusive power over federal elections, free from state constitutional constraints. The Court held that the Elections Clause (Art. I, §4) allows state legislatures to regulate federal elections, but state courts retain the power to review election laws under state constitutions, and legislatures are subject to ordinary state constitutional limits.

Issue
Does the Elections Clause vest exclusive, non-reviewable authority in state legislatures to regulate congressional elections, such that state courts cannot enforce state constitutional limits on that authority (the 'independent state legislature theory')?
Held
No. The Elections Clause does not insulate state legislatures from ordinary state constitutional constraints. State courts may review election laws under state constitutions, subject to the usual rule that the ultimate interpretation of state law is a matter for state courts.
Ratio Decidendi
The word 'Legislature' in the Elections Clause refers to the state's lawmaking process, which is defined and constrained by the state constitution. When the Constitution vests authority in a state 'Legislature,' it incorporates the standard state lawmaking procedures, including gubernatorial veto (where provided) and judicial review. The clause does not grant state legislatures a superpower to override state constitutional provisions. State court judgments about state law are ordinarily binding on federal courts, except in narrow circumstances where they violate federal constitutional guarantees (e.g., due process).
Obiter Dicta
Justice Thomas concurred separately, arguing that the state court's interpretation of state law could be wrong, but the Elections Clause itself does not independently bar state court review. Justice Kavanaugh concurred, emphasizing that federal courts can review state court decisions that violate federal constitutional rights (e.g., by changing election rules too close to an election under Purcell).

Exam Tips
Revision Checklist
- Name the issue before discussing facts so the marker sees the legal question immediately.
- State the holding in one sentence, then use the ratio to explain why the court reached that result.
- Use the citation and jurisdiction to show why this authority matters for the problem you are answering.
- Pair this case with one supporting or contrasting authority if the question tests limits, policy, or exceptions.
Problem Question Use
Common Pitfalls
- Thinking Moore v. Harper gives state courts unlimited power to override election laws (it does not; state court decisions are still subject to federal constitutional limits like due process)
- Confusing the 'independent state legislature theory' (rejected) with the recognized principle that state legislatures have primary responsibility under the Elections Clause
- Assuming that after Moore, state courts can never be reviewed by federal courts in election cases (there is still a narrow role for federal review, e.g., Bush v. Gore situation or Purcell principle).
