Case law is law based on judicial decisions rather than law based on constitutions, statutes, or regulations. It concerns unique disputes resolved by courts using the concrete facts of a case. Case law is also used interchangeably with common law, referring to the collection of precedents and authority set by previous judicial decisions on a particular issue or topic. In common law countries, including the United States, United Kingdom, and Canada, case law is used for judicial decisions of selected appellate courts, courts of first instance, and other bodies. These precedents are used to help courts decide what to do in new cases, and they can be found in print publications called reporters or electronically.

Case law vs statutory law
Case law, also known as common law, is based on judicial decisions rather than laws based on constitutions, statutes, or regulations. It concerns unique disputes resolved by courts using the concrete facts of a case. Case law is created by a judicial body, such as the Fourth Circuit Court of Appeals or the Virginia Supreme Court. It refers to the collection of precedents and authority set by previous judicial decisions on a particular issue or topic.
Statutory law, on the other hand, is created by a legislative body, such as the US Congress or the State of Maryland General Assembly. These laws are prescribed in specific statutes and are passed on different levels of government, such as local, state, and/or federal levels. The process of creating statutory law differs from case law. For example, a statute may be passed on the federal level, but its implementation and enforcement may vary depending on the state.
In common law countries, including the United States, United Kingdom, Canada, and others, case law is used for judicial decisions of selected appellate courts, courts of first instance, and other bodies. Common law systems follow the doctrine of stare decisis, where most courts are bound by their previous decisions in similar cases. According to stare decisis, lower courts should make decisions consistent with the previous decisions of higher courts.
When a judge is considering an argument, they take into account prior case law on the same or similar issues, which is referred to as "precedent." Precedent plays a crucial role in developing new case law. For example, in the case of R v Jogee, the Supreme Court of the United Kingdom ruled that it and other courts had misapplied the law for nearly 30 years, demonstrating the potential impact of precedent on legal outcomes.
While case law and statutory law differ in their creation and application, they are both crucial to the legal system. Understanding the various types of laws and how they may apply is essential for legal research and practice.

Judicial decisions
Case law is law based on judicial decisions rather than law based on constitutions, statutes, or regulations. Case law concerns unique disputes resolved by courts using the concrete facts of a case. Judicial decisions are opinions that help courts decide what to do in new cases and are also referred to as legal precedent. Whether a court must follow case law depends on factors such as whether the case has the same type of facts, which court decided the case, and when it was decided.
In common law countries, including the United States, United Kingdom, Canada, and Australia, case law is used for judicial decisions of selected appellate courts, courts of first instance, agency tribunals, and other bodies discharging adjudicatory functions. In the common law tradition, courts decide the law applicable to a case by interpreting statutes and applying precedents, which record how and why prior cases have been decided.
Common law systems follow the doctrine of stare decisis, by which most courts are bound by their own previous decisions in similar cases. According to stare decisis, all lower courts should make decisions consistent with the previous decisions of higher courts. For example, in England, the High Court and the Court of Appeals are each bound by their own previous decisions. However, a notable example of when the court has overturned its precedent is the case of R v Jogee, where the Supreme Court of the United Kingdom ruled that it and other courts had misapplied the law for nearly 30 years.

The role of case law in civil and common law traditions creates differences in the way that courts render decisions. A notable example of when the court has overturned its precedent is the case of R v Jogee, where the Supreme Court of the United Kingdom ruled that it and the other courts of England and Wales had misapplied the law for nearly 30 years. Generally, higher courts do not have direct oversight over lower courts of record, and the burden rests with litigants to appeal rulings to the higher courts.

Precedent
Case law is law based on judicial decisions rather than law based on constitutions, statutes, or regulations. It concerns unique disputes resolved by courts using the concrete facts of a case. Case law is used interchangeably with common law and refers to the collection of precedents and authority set by previous judicial decisions on a particular issue or topic.
The weight given to precedent can vary depending on several factors. These include the similarity of facts between the current case and the previous case, the age of the previous decision, and the hierarchy of the court that decided the previous case. For example, a decision by the Supreme Court of the United States is binding on all federal courts and state courts on issues concerning the Constitution and federal law. On the other hand, a decision by a lower court may be persuasive but is not binding on other courts.
Courts are generally expected to follow precedent, and deviations from precedent typically require compelling justifications. However, there are mechanisms by which precedent can be challenged and potentially overturned. For instance, a lower court may express that it hopes a higher court or the legislature will reform a rule established by precedent. If a case is appealed, an appellate court may have the opportunity to review and potentially overrule the previous precedent, setting a new precedent of higher authority.

Federalism
One such question concerns the scope of Congress's powers. The Constitution enumerates Congress's powers, and courts must sometimes determine whether a federal law falls within these enumerated powers. For example, in the case of the Affordable Care Act, a group of states argued that the individual mandate provision exceeded Congress's powers.
Another issue that arises in federalism is the conflict between state and federal laws. When this occurs, the Supremacy Clause dictates that federal law prevails and "preempts" state law. This doctrine of preemption is frequently litigated and can be complex, especially when state laws attempt to regulate activities in other states.
The Supreme Court plays a crucial role in interpreting the balance of power between the federal and state governments. Its decisions can define the limits of governmental authority and individual rights, impacting the federal-state dynamic. For instance, the Taney Court engaged in federalism rebalancing by limiting Congress's power to create federal law while also restricting state power in diversity cases.
In summary, federalism in the United States entails a division of power and a complex interplay between federal and state laws and authorities. The Supreme Court and attorneys general play pivotal roles in interpreting and defending the principles of federalism, respectively, ensuring a balanced governance system.
