In a democracy that naturally faces profound and wide-ranging disagreements about policy and law, the U.S. Supreme Court exercises its constitutional power to settle some of our nation’s toughest questions.
When a state sues another state, when federal laws contradict one another, or when we disagree about the application of the Constitution, the Supreme Court is empowered by Article III of the Constitution to make the final call.
The Supreme Court has the final say on legal disputes because it’s the highest court in the country.
It’s made up of nine justices who serve lifetime terms, bringing deep legal experience to the bench. They are nominated by the president and confirmed by the Senate.
Most of the time, the court acts as a reviewer of lower court decisions, exercising what’s known as appellate jurisdiction. There are rare instances in which the court has what’s called original jurisdiction, meaning it’s the first and only place a case is heard. These cases include things like disputes between states or involving ambassadors.
When the Supreme Court looks at lower courts’ decisions, it’s usually to settle major questions about the Constitution or federal law. The court’s job is to resolve legal questions that affect the entire country, not to fix every error. The Supreme Court justices choose which cases to hear, often stepping in when lower courts disagree on how to interpret the law (a circuit split) or when a significant federal question needs clarity.
In many ways, the Supreme Court works like a referee in a close game, making the tough calls and keeping things fair so the system, and our democracy, can keep running smoothly. In each case, the justices look at the facts, the text of the law, the context in which it was written, and how similar cases have been decided before.
When the Supreme Court rules, it creates a binding precedent, under a doctrine called stare decisis, which literally means to “stand by the thing decided.” In practice, that means lower courts are expected to follow the Supreme Court’s application in similar cases. The Supreme Court itself usually sticks to its past decisions as well, unless there’s a strong reason to revisit them. This consistency matters. It helps people understand how the law will be applied, ensures similar cases are treated alike, and reinforces trust in a legal system built on the rule of law.
The Supreme Court doesn’t have the power to make or enforce laws. Congress does the former, and the executive branch handles enforcement. The court’s role is to render judgments as issues arise.
Having an independent judicial branch provides accountability and is essential to a functioning democracy. It’s essential to the system of checks and balances that our founders built into the Constitution to ensure that no part of government had unchecked or unlimited power.
The court’s role is to ensure the Constitution is followed and the rights it guarantees are upheld across the country. In other words, it ensures we stick to the rulebook. And its decisions don’t just stay in the courtroom; they shape everyday life. Link in the landmark 1954 case Brown v. Board of Education, which ruled that segregation in public schools violated the Constitution’s guarantee of equal protection. Or in the 1963 case, Gideon v. Wainwright, which established that all criminal defendants have a Constitutional right to counsel.
The Supreme Court is a powerful check against overreach by the other branches and states. It inherently has its limits. Founding father Alexander Hamilton explained in Federalist No. 78, the court has “neither force nor will, but merely judgement.” It cannot enforce its own rulings; it must rely on the executive branch to do so. It cannot initiate cases; real disputes must be raised before it can address them. And, most importantly, it relies heavily on public trust and confidence. All of which provide checks on the court’s power.
In a system built to navigate the inevitable disagreement that exists in a democracy, the Supreme Court provides final, reasoned decisions to some of the most pressing questions in the country. It shapes how the Constitution is applied in real life, with consequences that reach far beyond the courtroom. Knowing how the Supreme Court works helps us understand its crucial role in upholding checks and balances, protecting our constitutional order, and guarding the rights we all hold dear.
Democracy is a verb.
