State Law Supremacy: Can It Override Federal Law?

The United States is made up of 50 states, each with its own set of laws that govern the daily lives of its residents, visitors, and businesses. State laws address the vast majority of legal issues and cases that arise in the nation, with federal law covering a few areas such as immigration, bankruptcy, and patent law. State laws can vary significantly from state to state, and even developments in the law of one state may influence the laws of another. This variation in state laws can lead to conflicts with federal laws, particularly in areas such as the decriminalization of marijuana, where federal law may supersede state-level statutes. Understanding the relationship between state and federal law is crucial, as it determines the authority and jurisdiction of each legal system.

State law vs federal law

The United States uses a system of government called federalism, which divides powers between national and regional governments. This allows states to test ideas independently and act as "laboratories of democracy". The US Constitution is the foundation of federal law and is the supreme law of the land. Federal laws apply to everyone in the United States and are decided by the Legislative Branch of the federal government (Congress). Congress may also pass legislation to enact new federal laws and amendments to the Constitution. The federal courts, including the US Supreme Court, uphold federal law, which includes matters that fall into immigration law, bankruptcy law, civil rights law, and social security law.

State laws, on the other hand, apply to people who live or work in a particular state and are implemented by the state legislature and confirmed by the state governor. State laws can never reduce or restrict the rights of a US citizen, but they can afford state residents more rights. For example, a state law that grants additional rights to citizens that wouldn't be granted by federal law will prevail over federal law. State courts have jurisdiction over matters like criminal law, real estate law, and welfare matters.

There are some areas of law that are governed by both state and federal law, such as when federal funds are offered to a state. In cases of conflict between federal and state law, federal law takes priority due to the Supremacy Clause in Article VI of the Constitution. This clause states that federal law cannot be impeded or restricted by any state law.

State law and sovereignty

In the context of the United States, state laws refer to the laws that exist in each of the 50 states, which have diverged significantly since independence. While state courts regularly share jurisdiction with federal courts, state laws cover a wide range of areas, including tort law, family law, property law, contract law, and criminal law. In most U.S. states, certain areas of the law, such as contract law, are primarily based on case law, with limited statutory modifications. However, some states, like California and Montana, have largely enacted civil codes.

The concept of state sovereignty, as discussed by Bodin, suggests that sovereigns who make the laws are not bound by them. However, this interpretation has been disputed, emphasizing that sovereigns are still bound by fundamental laws and rules derived from divine law, natural law, and the laws common to all nations. In the international context, state sovereignty is recognized by international law, and it grants states the right to regulate the entry and stay of foreign nationals, as well as the right to grant nationality.

The relationship between state law and sovereignty is complex. While states are considered sovereign, they have ceded certain aspects of their sovereignty to the federal government. This means that in areas where the Constitution grants power to the federal government, federal law takes precedence over state law. For example, the federal government can regulate matters that impact interstate commerce, even if they occur entirely within one state.

However, state sovereignty is not absolute, and it exists in tension with international law and human rights obligations. States have accepted limitations on their sovereign rights and have obligations to respect, protect, and fulfill human rights, including the rights of migrants. These obligations arise from international treaties and principles negotiated and established by states themselves to maintain peaceful relations and global order.

State law and the constitution

The Constitution of the United States is the supreme law of the United States of America. It outlines the frame of the federal government, which is divided into three branches: the legislative, the executive, and the judicial. Each state is governed by its own constitution, and state constitutions vary in length and scope. They are generally broader in scope and are amended more frequently than the federal Constitution.

State laws have diverged significantly since independence, and the United States cannot be regarded as one legal system. Instead, it can be seen as 50 separate systems of tort law, family law, property law, contract law, criminal law, and so on. Most cases are litigated in state courts and involve claims and defences under state laws.

The Supremacy Clause is a constitutional provision that identifies the supremacy of federal law. It assumes the underlying priority of federal authority, and all federal and state governments must stay within the boundaries of the Constitution. Federal law overrides state law when the Federal government has jurisdiction, and in cases of conflict, federal law wins.

Uniform acts are proposed by private organisations to cover areas of law traditionally governed by states, and they can become state law if enacted by the state legislature. The most successful uniform acts are the Uniform Commercial Code and the Model Penal Code.

State law and uniform acts

In the United States, both the federal government and individual state governments have the power to pass laws. However, the increased movement of people and businesses across state lines has led to a growing need for uniformity in state laws. This has given rise to the concept of "Uniform Laws" or "Uniform Acts", which are model laws collaboratively written and proposed for adoption by all states to create a consistent legal framework across the country.

Uniform Laws are drafted by the Uniform Law Commission (ULC), previously known as the National Conference of Commissioners on Uniform State Laws (NCCUSL). The ULC is composed of legal experts, including lawyers, judges, legislators, and law professors, who work to promote uniformity in state laws. The drafting process for a Uniform Law can take at least two years, and sometimes even longer, to ensure careful consideration and review.

The goal of Uniform Acts is to facilitate the enactment of identical or similar laws across all states. While some acts have been widely adopted, others have seen limited success. To date, more than 200 Uniform Laws have been approved by the ULC, with over 100 adopted by at least one state. Examples of influential Uniform Acts include the Uniform Commercial Code, the Uniform Probate Code, the Uniform Partnership Act, and the Uniform Child Custody Jurisdiction and Enforcement Act.

It is important to note that Uniform Acts are not laws in themselves. They are legislative proposals that must be enacted into law by state legislatures. As a result, persons conducting business or legal matters across different states must always check the local laws to ensure compliance with the specific state's legal requirements. While uniformity is a primary goal, it is not always achieved, and state-by-state variations in laws can still exist.

State law and the Supreme Court

The United States Supreme Court was established in 1789 by the Judiciary Act of Congress. The Supreme Court is the country's court of last resort and has the authority to act in cases arising under the Constitution, laws, and treaties of the United States. It also handles controversies involving the US, disputes between states or citizens of different states, and cases of admiralty and maritime jurisdiction.

State laws in the US have diverged significantly since independence, resulting in 50 distinct systems of law, including tort law, family law, property law, and criminal law. State courts regularly share jurisdiction with federal courts and are bound by federal law. However, in some cases, state laws can conflict with federal laws. While the states have ceded certain aspects of their sovereignty to the US, they retain the power to make laws in areas not expressly granted to the Federal government by the Constitution. For example, the Federal government can regulate matters that impact interstate commerce, but it cannot enter into treaties with foreign powers without the involvement of the Federal government.

The Supreme Court plays a crucial role in resolving conflicts between state and federal laws. It also clarifies limits on state immunity in employment claims, as seen in a case involving the Royal Embassy of Saudi Arabia, where the Court ruled that the Embassy was not entitled to state immunity in an employment tribunal claim.

In addition, the Supreme Court's decisions can have significant political implications for states. For instance, the Supreme Court's ruling in Roe v. Wade, which ended the constitutional right to abortion, briefly made abortion inaccessible in Wisconsin due to a pre-existing state ban. The Wisconsin Supreme Court's decisions have also been known to tip the state's balance of power, with high-profile and high-stakes elections determining the court's composition.
