Federal Power: Can States Be Overruled?

The relationship between the states and the federal government is a fundamental aspect of the US Constitution and has been a source of tension and debate. The Supremacy Clause, found in Article VI, section 2 of the US Constitution, establishes federal law as the supreme law of the land, giving it priority over state laws in cases of conflict. This is known as preemption, where federal statutes override state laws, and has been recognised and applied by the US Supreme Court. However, the scope of federal power and the instances where it should override state law are still contested, with no settled answer.

The Supremacy Clause

While the Supremacy Clause establishes the supremacy of federal law over state law, the specific powers of the federal government and the scope of its authority are still debated. The interpretation and application of the Supremacy Clause by the Supreme Court have evolved over time, reflecting legal and political trends and the changing relationship between the federal government and the states. The Supremacy Clause continues to be a fundamental aspect of the U.S. Constitution, shaping the dynamic between the federal government and the states.

State and federal law conflict

The relationship between the states and the federal government is one of the most fundamental and contested fault lines of constitutional theory in the US. The US Constitution declares that federal law is "the supreme law of the land". This is known as the Supremacy Clause, which states that federal law prevails over conflicting state law. The Supremacy Clause is among the Constitution's most significant structural provisions.

However, the relationship between state and federal law is not always straightforward, and there are several nuances to consider. Firstly, determining whether federal law preempts state law requires an extensive analysis. While Congress can include specific language in a statute that preempts state law, preemption can also be implied by other factors. For example, implied preemption can occur when state and federal laws directly conflict with each other, or when federal laws dominate a field that a state law seeks to regulate. A conflict may occur when state and federal laws impose different requirements on a party, making it impossible to comply with both or putting a party in violation of one law when complying with the other.

Secondly, the Supreme Court has the power to reverse the decisions of state supreme courts and interpret the Constitution and federal law, which state courts must accept. However, the Supreme Court is deeply divided over questions regarding the limits of Congress's legislative powers and the extent to which states can assert sovereign immunity in relation to federal law.

Lastly, while the Supremacy Clause establishes federal supremacy, there is ongoing debate about the scope of federal powers and when federal authority should override state law. This debate centres around two visions: nationalism and federalism. The nationalist vision imagines a single national people represented by a superior federal government, while the federalist vision sees states delegating certain powers to a federal government acting as their agent.

Field preemption

The preemption doctrine refers to the idea that a higher authority of law will override the law of a lower authority when the two conflict. In the United States, the federal government can override state law under the Supremacy Clause (Article VI, Section 2) of the U.S. Constitution, which states that federal law is "the supreme law of the land". This is known as preemption.

An example of field preemption is the case of Pennsylvania v. Nelson (1956), where it was found that federal law completely occupied the field of criminal sedition, leaving no room for states to regulate. Another example is Gade v. National Solid Wastes Management Association (1992), where the Supreme Court ruled that federal laws governing hazardous waste preempted Illinois laws covering the same field. The Court based its ruling on the large number of regulations promulgated by the Occupational Safety and Health Administration to implement the Occupational Safety and Health Act and the Superfund Amendments and Reauthorization Act of 1986.

Implied preemption can occur when federal law dominates a field that a state law seeks to regulate. This can happen when there is clear legislative intent that the "field" is preempted by state law. The "field" is usually defined as when there is an extensive scope of state regulation, reflecting a state intent to preempt all local regulations in a particular area. Occupation of the field is likely to be found when state law addresses an area that has traditionally been a matter of the state, such as the mortgage foreclosure process.

Congress's authority

The relationship between the states and the federal government is one of the most fundamental and contested fault lines of constitutional theory in the US. The Supremacy Clause, found in Article VI, section 2 of the US Constitution, establishes that federal law is "the supreme law of the land". This means that when a federal law conflicts with a state or local law, the federal law will supersede the other law or laws. This is known as "preemption".

Congress can include specific language in a statute that preempts state law, but preemption can also be implied by other factors when state and federal laws directly conflict with each other, or when federal laws dominate a field that a state law seeks to regulate. For example, in Gade v. National Solid Wastes Management Association, the Supreme Court ruled that federal laws governing hazardous waste preempted Illinois laws covering the same field, citing the vast body of regulations promulgated by the Occupational Safety and Health Administration.

Preemption can arise in any area over which Congress has authority, but it is most often an issue in areas in which Congress and the states share authority. The Supreme Court has established requirements for preemption of state law and has cautioned that, when evaluating evidence of Congressional intent, courts should err on the side of state rather than federal authority.

Supreme Court's role

The US Constitution declares that federal law is "the supreme law of the land". This is known as the Supremacy Clause, which can be found in Article VI, Section 2 of the Constitution. The Supremacy Clause establishes that federal law supersedes state laws in the event of a conflict between the two.

The role of the Supreme Court is to interpret the Constitution and federal law, and it has the power to reverse the decisions of state supreme courts. The Supreme Court has recognised various ways in which federal statutes can override or "preempt" state law. This can occur when federal laws dominate a field that a state law also seeks to regulate, or when there is a direct conflict between federal and state laws, making it impossible for a party to comply with both.

The Supreme Court has ruled on several cases involving preemption, including Sperry v. Florida in 1963, where a conflict arose between federal patent laws and a state law governing the licensure of attorneys. The Court has also recognised "field preemption", where federal laws and regulations have so thoroughly covered a field that there is no room for state laws to operate. An example of this is Gade v. National Solid Wastes Management Association in 1992, where federal laws governing hazardous waste were found to preempt Illinois laws on the same subject.

In addition to interpreting the Constitution and federal law, the Supreme Court also establishes requirements for preemption of state law. While Congress can include specific language in a statute that preempts state law, the Court has determined that even in the absence of such language, preemption can be implied by other factors. The Court has cautioned, however, that when evaluating evidence of Congressional intent, courts should err on the side of state rather than federal authority.
