State Constitutions
State constitutions and the U.S.
20. State Constitutions
State constitutions, like Nevada’s, may expand individual rights beyond those provided by the U.S. Constitution, but cannot diminish someone’s U.S. constitutional rights.
- The constitutions of many states, including Nevada’s, include some provisions that parallel protections of the U.S. Constitution, and some that are unique to the state constitution.
- State constitutions may provide broader protections than the U.S. Constitution but cannot diminish someone’s U.S. Constitutional rights.
- State laws cannot violate the state’s constitution unless the state constitutional provision at issue itself violates the U.S. Constitution, and therefore is invalid.
The U.S. Constitution sets a floor of individual rights every state must honor. A state constitution may build above that floor, giving more protection, but never below it; a provision that gives less is invalid to the extent of the conflict.
State constitutions and the U.S. Constitution are not two equal sources that can each cancel the other out. The relationship runs in one direction. The U.S. Constitution sets a floor of individual rights that every state must honor, and a state constitution is free to build above that floor but never below it. So a state constitution may give its residents more protection than the federal Constitution requires, for example a broader free-speech guarantee or a stronger privacy right, and that extra protection is perfectly valid because it does not take anything away from anyone's federal rights.
The limit is the diminishing limit. A state constitution cannot cut a federal right below the federal minimum. If a state constitutional provision purports to give someone less than the U.S. Constitution guarantees, that provision is invalid to the extent of the conflict, and it cannot be enforced. This also answers what happens when a state law is challenged. A state law that conflicts with the state constitution normally falls, because the state constitution is the higher state-law authority. But there is one twist: if the very state constitutional provision being used to strike the law itself violates the U.S. Constitution, that provision is invalid, so it cannot be the basis for invalidating the state law. In short, the federal Constitution is the ceiling on how little protection a state may provide and the floor that no state may drop beneath; a state constitution controls within the state only so long as it stays at or above that federal floor.
Note the parallel-versus-unique point: many state provisions mirror federal protections, while others are unique to the state, but neither feature changes the one-directional rule. Whether a provision is unique or parallel says nothing about whether it is valid.
One direction only: a state constitution is a floor-raiser, never a floor-lowerer.
It can give more protection than the U.S. Constitution, never less.
The federal Constitution is the floor no state may drop beneath.
Two throwaway facts that never decide it: "the provision is unique to the state" and "the provision parallels the federal one." Whether a provision is unique or parallel says nothing about whether it is valid.
The only questions that matter: does it give more, or does it try to give less?
More is fine; less is invalid.
a state may expand a federal right but may never diminish one, and a state provision that itself violates the U.S. Constitution is invalid and cannot strike a state law.
A state's constitution contains a search-and-seizure clause that, as interpreted by the state's highest court, protects residents against certain searches that the U.S. Constitution would allow. A resident, relying on that clause, challenges a search that the federal Constitution would permit.
Suppose instead the state provision purported to allow searches that the U.S. Constitution forbids, so it gave residents less protection than the federal floor. That provision would be invalid to the extent it diminishes a federal right, and a court could not enforce it against the resident.
An answer that treats the U.S. Constitution as a CEILING, saying a state constitution cannot give MORE protection than the federal Constitution, or that a parallel provision is capped at exactly the federal level.
The federal Constitution is a floor, not a ceiling. A state constitution may provide broader protection than the U.S. Constitution; only diminishing a federal right is forbidden.An answer that lets a state constitution cut a federal right below the federal minimum, or invents a subject-matter limit (for example, civil-only) on what a state constitution may cover.
The rule is one-directional and has no subject-matter limit in scope. A state may expand but never diminish a federal right; a provision that diminishes one is invalid.An answer that turns on whether a provision is unique to the state constitution or parallels a federal protection, as if that feature decided validity.
Unique-versus-parallel is a printed feature of state constitutions but it does not decide validity. Only more-versus-less protection does.An absolute: a state may grant ANY protection with no limit, a state law ALWAYS prevails over the state constitution, or a state constitution is binding REGARDLESS of content.
The limits are real. The diminishing limit caps a state's expansion, a conflicting state law normally falls to the state constitution, and a provision that itself violates the U.S. Constitution is invalid.An answer that misorders the sources: a state constitution overriding the federal floor, or a state law surviving even though it conflicts with a valid state constitutional provision.
The federal Constitution is the supreme floor; within the state, a valid state constitution controls over a conflicting state law, while an invalid state provision controls nothing.the stem hands you a state constitutional provision (or a state-court interpretation of one) set against the U.S. Constitution, and asks whether the state provision is valid or whether a state law survives.
The instant you see a state constitution pitted against the federal Constitution, run the direction check.
ask: does the state provision give more protection than the U.S. Constitution, or less?
More is valid; less is invalid to the extent it diminishes a federal right.
If the question is about a state law, ask whether the state constitutional provision used to strike it is itself valid under the U.S. Constitution; if that provision violates the federal Constitution, it is invalid and cannot invalidate the state law.
Distrust any answer that rides on the provision being unique or parallel, or that lets a state drop below the federal floor or treats the federal Constitution as a ceiling on more-generous state rights.
A state's highest court interpreted a privacy clause in the state constitution to protect residents against a kind of government data collection that the U.S. Constitution would permit. A resident challenged that data collection, relying on the broader state guarantee, and the state argued that a state constitution cannot give residents any more protection than the U.S. Constitution provides.
Under existing precedent, is the broader state privacy guarantee valid?
A state amended its constitution to add a provision authorizing the state to compel a criminal defendant to give certain self-incriminating testimony that the U.S. Constitution forbids the government to compel. A defendant subjected to that compulsion challenged the provision, and the state defended it as a validly enacted part of its own constitution.
Under existing precedent, is the state constitutional provision valid?
A state legislature passed a state law. A resident challenged the law in state court, arguing it conflicts with a provision of the state constitution. The state constitutional provision at issue is itself valid under the U.S. Constitution, and the state law does in fact conflict with it.
Under existing precedent, should the state law be held invalid?
A state law restricted a particular kind of demonstration on public sidewalks. A resident challenged the law in state court, relying on a provision of the state constitution. That state constitutional provision, as written, purports to authorize the very restriction the state law imposes, but the provision itself diminishes a speech right guaranteed by the U.S. Constitution.
Under existing precedent, can that state constitutional provision be used to uphold the state law?
A state constitution contains a free-exercise provision that parallels the protection in the U.S. Constitution and, as interpreted by the state's highest court, also protects a category of religious conduct that the U.S. Constitution does not reach. A resident relied on the additional state protection, and the state argued that because the state provision parallels the federal one, it can offer no more than the federal Constitution offers.
Under existing precedent, is the additional protection under the state provision valid?
