Case law, also known as precedent or common law, refers to the body of prior judicial decisions used by judges to decide on issues before them. In the US, the Supreme Court is the highest court, and its decisions are binding on all federal and state courts. Lower federal courts include the US Courts of Appeals, US District Courts, the US Court of Claims, and the US Court of International Trade and US Bankruptcy Courts. Each district court falls under the jurisdiction of a circuit court, and the opinions of that circuit court will be binding on that district court. For example, a decision by the US Court of Appeals for the Fifth Circuit is binding on all federal district courts within the Fifth Circuit, but it is not binding on a court sitting outside of that circuit, such as in California.

Federal courts are bound by the decisions of the US Supreme Court
The US Supreme Court is the highest court in the country and acts as the court of last resort for those seeking justice. Federal courts are bound by the decisions of the US Supreme Court on US Constitutional and other issues of federal law. This is because the Supreme Court has the power of judicial review, which ensures that each branch of government recognizes the limits of its power. The Supreme Court also protects civil rights and liberties by striking down laws that violate the US Constitution.
The US Supreme Court comprises one Chief Justice and eight Associate Justices. The Court's opinions are published in three stages. First, a slip opinion is made available on the Court's website and through other outlets. Next, several opinions and lists of the Court's orders are bound together in paperback form, called a preliminary print of the United States Reports. Finally, the official version of the Court's opinions is published in a series of books called the United States Reports.
The Supreme Court has original jurisdiction over certain cases, such as suits between two or more states and cases involving ambassadors and other public ministers. It also has appellate jurisdiction over almost any other case involving a point of constitutional or federal law. For example, the Supreme Court can hear cases where the United States is a party, cases involving treaties, and cases involving ships on the high seas and navigable waterways (admiralty cases).
The Supreme Court's size and membership have changed over time, with various Acts of Congress altering the number of seats. The Judiciary Act of 1789, for instance, established a six-member Supreme Court, while after the Civil War, the number of seats was fixed at nine.
In summary, federal courts are bound by the decisions of the US Supreme Court on Constitutional and federal law issues. The Supreme Court plays a crucial role in interpreting the Constitution and ensuring that the actions of the government branches remain within their constitutionally defined limits.

State courts may hear cases involving federal laws
The United States judicial system is a complex network of federal and state courts, each with its own jurisdiction and authority. While federal courts typically handle cases arising under the United States Constitution, federal statutes, or treaties, state courts also play a crucial role in interpreting and applying federal laws. In certain circumstances, state courts may hear cases involving federal laws, creating an interplay between the two court systems.
Federal courts are courts of limited jurisdiction, meaning they primarily handle cases authorized by the United States Constitution or federal statutes. The federal district court is typically the starting point for cases involving federal statutes, the Constitution, or treaties, exercising what is known as "original jurisdiction." However, state courts also have the authority to hear cases involving federal laws in specific scenarios, leading to an overlap in jurisdiction between federal and state courts.
One such scenario is when a plaintiff chooses to bring a case involving federal law in state court. The plaintiff has the initial choice of forum, and if they opt for state court, the case will be heard by the state judicial system. However, in such cases, the defendant has the option to "remove" the case to federal court if they believe it falls under federal jurisdiction. This dynamic showcases the interplay between federal and state courts, where the plaintiff's choice of forum can be balanced by the defendant's right to seek a federal forum.
Additionally, state courts may hear cases involving federal laws when they involve substantive issues of state law. In these instances, even if the case is heard in federal court, the decisions of the state supreme court on the specific state law issue would be binding. This scenario underscores the deference given to state courts on matters of state law, even when heard in the context of a federal court case. For example, if a case involves a state law issue similar to the First Amendment, the federal Supreme Court would not have jurisdiction to consider an appeal, as it solely deals with issues arising under the United States Constitution.
Furthermore, federal courts may also exercise what is known as "diversity jurisdiction" in certain cases. Diversity jurisdiction allows a plaintiff from one state to file a lawsuit in federal court when the defendant is located in a different state. This scenario provides another avenue for federal courts to hear cases, even if they do not directly involve federal laws, by ensuring representation for plaintiffs across state lines.
While state courts may hear cases involving federal laws in specific circumstances, it is important to note that the United States Supreme Court is the highest court in the land. It has the power to decide appeals on all cases brought in federal court or those brought in state court dealing with federal law. This includes cases where a state supreme court has ruled on a matter involving federal law, such as a First Amendment freedom of speech case. The Supreme Court can review such cases and provide the final interpretation of federal laws, ensuring uniformity in their application across the nation.

Each district court falls under a circuit court's jurisdiction
Each district court falls under the jurisdiction of a circuit court, and the opinions of that circuit court are binding on that district court. For example, the 9th Circuit Court is the federal circuit court for California, and the Central District Court of California is the federal district court for Los Angeles. Therefore, the opinions of the 9th Circuit Court are binding in the Central District Court of California.
The U.S. Supreme Court is the highest court in the United States. Lower courts on the federal level include the U.S. District Courts, which are the trial courts where legal actions are initially filed. The Court of Appeals is the intermediate appellate court, and the Supreme Court is the final appellate court. There are 94 federal district courts, with at least one district in each state, as well as in the District of Columbia, Puerto Rico, the U.S. Virgin Islands, Guam, and the Northern Mariana Islands.
The Court of Appeals is divided into 12 regional circuits, each encompassing specific judicial districts. The decisions of the Court of Appeals are binding on the district courts within its circuit. For example, a decision by the U.S. Court of Appeals for the Fifth Circuit is binding on all federal district courts within the Fifth Circuit. However, a court sitting in California is not strictly bound to follow the Fifth Circuit's prior decision.
While the decisions of higher courts in the same jurisdiction are considered mandatory authority, state court decisions typically control on substantive issues of state law. For example, in a federal court case with a state law issue, the decisions of the state supreme court would be binding. Decisions of the state court of appeals may also be useful, but federal courts might treat them as persuasive authority. While it is best to cite controlling authority, citing non-binding cases as relevant persuasive authority can be useful when there is little or no binding authority for an issue in a particular jurisdiction.

State supreme court decisions are binding on federal courts
The United States Constitution establishes a federal system of government, with power shared between the federal government and the state governments. Both federal and state governments have their own court systems. The federal court system is comprised of district courts, courts of appeals, and the Supreme Court. Each state also has its own court system, with its own terminology for naming the various levels of courts.
In the federal court system, the district courts are the trial courts where cases are initially filed. The Court of Appeals is the intermediate appellate court, and the Supreme Court is the final appellate court. Each district court falls under the jurisdiction of a circuit court, and the opinions of the circuit court are binding on that district court. For example, the 9th Circuit Court of Appeals' decisions are binding on the Central District of California, which is within its jurisdiction.
While the decisions of the U.S. Supreme Court are binding on all federal courts, state supreme court decisions are generally not binding on federal courts. However, there may be instances where a state supreme court decision becomes relevant in a federal court case. This typically occurs when a federal court case involves a substantive issue of state law. In such cases, the decision of the state supreme court on that specific issue of state law would be binding on the federal court. This is because state courts have the final authority on issues of state law.
It is important to note that while state supreme court decisions may be binding on federal courts in specific instances, the overall relationship between state and federal courts is complex. In general, federal courts have the final say on issues of federal law and the U.S. Constitution, while state courts have the final say on issues of state law. This division of authority ensures that both the federal and state court systems can interpret and apply the laws within their respective jurisdictions effectively.

US Supreme Court decisions are binding on all federal and state courts
In the United States, the decisions of the Supreme Court are binding on all federal and state courts on questions of constitutional interpretation and other issues of federal law. This means that all lower courts, including federal and state courts, must follow the decisions of the US Supreme Court when interpreting the US Constitution and federal laws.
The US court system is structured hierarchically, with the Supreme Court at the top, followed by the circuit courts, and then the district courts. This hierarchy determines the binding nature of case law. Courts are required to follow the decisions of higher courts in the same jurisdiction, making these cases mandatory authority.
At the federal level, each district court falls under the jurisdiction of a circuit court. The opinions of the circuit court are binding on the district courts within its jurisdiction. For example, the 9th Circuit Court of Appeals is the federal circuit court for California, and its decisions are binding on the Central District of California, which is a federal district court.
State courts are typically bound by the decisions issued by the higher courts in that state. For instance, California trial courts are bound by the opinions of the California Court of Appeals and the California Supreme Court. However, in cases where a federal court hears a matter involving a state law issue, the decisions of the state supreme court on that specific issue would be binding, even though the case is being heard in a federal court.
It is important to note that neither published nor unpublished district court decisions are binding precedent. However, they may still be considered persuasive by other courts, with published decisions generally carrying more weight than unpublished ones.
