State Law Vs Constitution: Who Wins?

The Supremacy Clause of the U.S. Constitution establishes federal law as supreme, with federal statutes and treaties taking priority over state laws. This means that a federal law can override a state constitution if there is a conflict between the two. However, federal laws must be within the parameters of the Constitution and cannot violate constitutional limits on federal power. While the Supremacy Clause ensures federal authority, it does not dictate that each state must base its laws on the same policy judgments reflected in federal statutes.

The Supremacy Clause

> "The power of the Constitution predominates. Anything, therefore, that shall be enacted by Congress contrary thereto, will not have the force of law."

Alexander Hamilton, in Federalist No. 33, wrote about the Supremacy Clause, arguing that federal laws, by definition, must be supreme. He noted that if federal laws do not function from a position of supremacy, they amount to nothing. Hamilton further emphasised the importance of delegated authority, stating that any legislative act contrary to the Constitution cannot be valid.

The US Supreme Court has played a significant role in interpreting and applying the Supremacy Clause. In various cases, the Court has established the supremacy of federal law and treaties, as well as asserted its power to review state court decisions involving federal law and constitutional interpretation.

Federal preemption

The Supremacy Clause of the U.S. Constitution establishes that federal law takes precedence over state law in the event of a conflict between the two. This is known as federal preemption, a cornerstone of the U.S. federal political structure. Federal preemption can occur in three ways: express preemption, conflict preemption, and field preemption.

Express preemption occurs when a federal statute explicitly confirms Congress's intention to preempt state law. An example of express preemption is the Airline Deregulation Act, which included language to ensure that states would not undo federal deregulation with their own regulations.

Conflict preemption occurs when a federal law directly conflicts with a state law, making it impossible to follow both at the same time. An example of conflict preemption is Mutual Pharmaceutical Co. v. Bartlett, where federal law prohibited generic drug manufacturers from changing FDA-approved labels, thus preempting state tort law from forcing manufacturers to add additional information to the labels.

Field preemption occurs when Congress intends for federal law to exclusively occupy a specific legislative field, thereby displacing any state law in that field. An example of field preemption is the Medical Device Regulation Act, where Congress preempted all state regulation in the field of medical devices.

It is important to note that federal preemption is not absolute. The Tenth Amendment to the U.S. Constitution reserves certain powers to the states, and Congress may not make laws that force state governments to act contrary to their constitutional authority. Additionally, the Supreme Court prefers interpretations that avoid preempting state laws, and state laws typically prevail when in conflict with local laws.

State law vs. federal law

The relationship between state law and federal law in the United States is governed by the Supremacy Clause, which establishes the supremacy of federal law. This clause, found in Article VI of the Constitution, provides that the Constitution, federal laws, and treaties made under the authority of the United States are the "supreme Law of the Land". This means that if a state law conflicts with a federal law, the federal law overrides the state law.

The Supremacy Clause is based on the principle that the federal government has supremacy over state governments and that the laws of the federal government are supreme over those of the states. This does not mean, however, that federal statutes can contradict the Constitution. Federal statutes and treaties must be within the parameters of the Constitution and must not violate constitutional limits on federal power, such as the Bill of Rights. It is the responsibility of the United States Supreme Court to exercise the power of judicial review and invalidate any statute that violates the Constitution.

While the Supremacy Clause establishes the priority of federal law, it is important to note that the US Congress cannot pass laws on everything. The Tenth Amendment to the United States Constitution states that the federal government only has the powers delegated to it by the Constitution. Some rights are therefore reserved for the states, and Congress can only legislate on issues affecting powers delegated to the federal government by the Constitution. For example, laws relating to abortion are generally within the purview of state constitutions, as Congress cannot make laws about them.

In some cases, federal laws may preempt state laws. For instance, the Voting Rights Act of 1965, an act of Congress, takes precedence over state constitutions. Similarly, Food and Drug Administration regulations may override state court judgments in cases involving prescription drugs. In certain situations, such as with the 1976 Medical Device Regulation Act, Congress may preempt all state regulation. However, in other cases, such as with labels on prescription drugs, Congress may set federal minimum standards while allowing states to impose more stringent regulations.

State constitutions

The Supremacy Clause of the U.S. Constitution establishes the supremacy of federal law over state law. This means that if a federal law conflicts with a state constitution, the federal law will override the state constitution. However, it's important to note that this does not mean that states have to base all their laws on federal statutes. For example, while Congress has established federal income taxes, states are free to choose whether or not to establish sales taxes.

The Supremacy Clause is a cornerstone of the U.S. federal political structure, ensuring that federal authority takes priority over state authority, as long as it is expressed in the Constitution. This means that federal statutes and treaties must be within the parameters of the Constitution and cannot violate constitutional limits on federal power, such as the Bill of Rights. The Tenth Amendment to the United States Constitution further clarifies this by stating that the federal government only has the powers delegated to it by the Constitution.

While the Supremacy Clause establishes the priority of federal law, there are still ways for states to exert their rights. For example, in the case of Denver and Boulder expanding their civil rights laws to protect LGBT people, Colorado voters approved a constitutional amendment that protected citizens from those laws, giving them a right to discriminate based on sexual orientation. This shows that while federal law takes precedence, states can still find ways to assert their rights within the constitutional framework.

In conclusion, while a state law cannot directly override the U.S. Constitution, the complex interplay between federal and state powers allows for a dynamic and flexible legal system. The Supremacy Clause ensures that federal law takes priority, but states retain significant autonomy in many areas, and their rights are further protected by the need for bipartisan support to pass overriding federal laws.

Judicial review

The Supremacy Clause is a cornerstone of the United States' federal political structure. It is a conflict-of-laws rule, specifying that federal acts take priority over any state acts that conflict with federal law. This is based on the principle that federal laws, by definition, must be supreme. If federal laws did not function from this position, they would amount to nothing.

The Supremacy Clause also applies to treaties, both those already made and those to be made in the future. This was specifically designed to encompass pre-existing agreements, such as the Treaty of Peace. The Supremacy Clause unquestionably makes such treaties possible, and federal statutes enacted by Congress are included in the "supreme Law of the Land".

The Supremacy Clause does not mean that each state must base all of its own laws on federal statutes. For example, Congress has established federal income taxes but has refrained from establishing federal sales taxes. States are not required to make the same choice, but they cannot exempt people from paying federal income taxes.

In some cases, federal law can override a state constitution. For example, the Voting Rights Act of 1965, an act of Congress, preempts state constitutions. In other cases, such as the 1976 Medical Device Regulation Act, Congress preempted all state regulation. In cases where it is unclear whether preemption should apply, the Supreme Court tries to follow lawmakers' intent and prefers interpretations that avoid preempting state laws.
