Case law is a crucial element of the legal system, providing guidance, consistency, and precedent for legal interpretations and rulings. It is a law that is based on precedents, or the judicial decisions from previous cases, rather than law based on constitutions, statutes, or regulations. Case law uses the detailed facts of a legal case that have been resolved by courts or similar tribunals. These past decisions are called case law or precedent. Stare decisis, a Latin phrase meaning let the decision stand, is the principle by which judges are bound to such past decisions, drawing on established judicial authority to formulate their positions.

What You'll Learn

Precedent
Case law is a law that is based on precedents, or the judicial decisions from previous cases, rather than laws based on constitutions, statutes, or regulations. Case law uses the detailed facts of a legal case that have been resolved by courts or similar tribunals. These past decisions are called "case law" or precedent.
The principle of stare decisis, a Latin phrase meaning "let the decision stand", is the doctrine by which judges are bound to past decisions. In other words, stare decisis dictates that courts should follow the decisions of higher courts in their jurisdiction. This means that lower courts are bound by the decisions of higher courts, and must make decisions consistent with those of the higher courts. For example, in the United States, a decision by the United States Supreme Court is binding precedent in all courts, while a decision by a lower court, such as the Court of Appeals, would not be binding on the Supreme Court.
In some cases, a court may choose to deviate from a previous decision or precedent, especially if it is deemed unjust or inconsistent with subsequent legal developments. For example, in R v Jogee, the Supreme Court of the United Kingdom ruled that it and other courts had misapplied the law for nearly 30 years, overturning its own previous precedent.
In summary, precedent is a crucial aspect of case law, providing guidance, consistency, and a basis for legal interpretations and rulings. It is shaped by judicial decisions and the appeals process, and helps to ensure the evolution and clarity of the legal system.

Consistency
In common law systems, such as in England and the United States, the doctrine of stare decisis is particularly prominent. For example, in England, the High Court and the Court of Appeals are bound by their previous decisions. Similarly, in the United States, lower courts must abide by the precedents set by the Supreme Court, which has the authority to overrule any lower court's ruling and establish new precedents.
The process of creating case law involves judicial reasoning and decision-making. Judges consider legal principles, statutes, and precedents before reaching a judgement. This judgement then becomes part of the body of case law, which serves as a reference for future cases. By following established precedents, judges ensure consistency in their rulings and avoid arbitrary or inconsistent interpretations of the law.
However, it is important to note that case law is not static and can evolve over time. While lower courts generally adhere to the decisions of higher courts, they may also seek to distinguish the present case from a binding precedent to reach a different conclusion. This can occur when legal developments or trends in legal reasoning render the precedent unhelpful or inconsistent with subsequent authority. Additionally, higher courts can overturn their previous decisions or deviate from them, as demonstrated in the case of R v Jogee in England, where the Supreme Court overturned its precedent and established a new ruling.
In summary, consistency in case law is achieved through the establishment of precedents and the adherence to stare decisis. This ensures a consistent framework for legal decision-making and helps shape the evolution of the legal system. However, case law also allows for flexibility and change when necessary, demonstrating the dynamic nature of the legal process.

Judicial decisions
Case law is a law that is based on precedents, or the judicial decisions from previous cases, rather than law based on constitutions, statutes, or regulations. Case law uses the detailed facts of a legal case that have been resolved by courts or similar tribunals. These past decisions are called "case law" or precedent.
Judges at every level of the court system refer to precedents while hearing a case, and attorneys often refer to case law in court as part of their arguments. In general, a case becomes case law when a decision is made by a higher court in the same jurisdiction and lower courts choose to adhere to the precedent set forth by that higher court's ruling. Case law is precedent that has been set based on prior judicial decisions, rather than specific statutes or regulations.
In common law traditions, courts decide the law applicable to a case by interpreting statutes and applying precedents that record how and why prior cases have been decided. Common law courts generally explain in detail the legal rationale behind their decisions, with citations of both legislation and previous relevant judgments, and often interpret the wider legal principles. The necessary analysis (called ratio decidendi) then constitutes a precedent binding on other courts.
In the US, the appeals court can overrule a lower court's ruling, establishing a new precedent. This appeals system goes all the way up to the Supreme Court, whose ruling provides the strongest precedent for case law, overruling any lower court's ruling.

Court hierarchy
Case law is a law that is based on precedents, that is, the judicial decisions from previous cases. It is a crucial element of the legal system, providing guidance, consistency, and precedent for legal interpretations and rulings. It is important to understand the hierarchy of courts when dealing with case law, as the decisions of higher courts are often binding on lower courts.
In the United States, the federal court system has three main levels: district courts, circuit courts, and the Supreme Court. District courts, also known as trial courts, are the starting point for any case arising under federal statutes, the Constitution, or treaties. They have original jurisdiction, meaning they preside over cases first, and there are 94 district courts across the country.
The next level is the circuit courts, also known as the courts of appeals. There are 13 appellate courts that review the decisions of the lower courts to determine if the law was applied correctly.
The Supreme Court is the highest court in the United States and the final level of appeal in the federal system. It is the only court established by the Constitution, and its decisions are binding on all other courts.
It is important to note that the federal court system operates alongside state courts. The plaintiff usually has the choice of bringing the case in state or federal court, depending on the nature of the dispute or crime. In some cases, the defendant may also be able to "remove" the case to federal court, especially if it involves state law and falls under the court's "diversity jurisdiction."
While higher courts generally adhere to their previous decisions and those of higher courts, they may deviate from them in certain circumstances. For example, a court may hold that a precedent is inconsistent with subsequent authority or that it can be distinguished by a material difference in the facts of the cases.
The hierarchy of courts is crucial in understanding how case law operates, as it determines the weight and applicability of judicial decisions across different courts.

Statutory law
Case law is a crucial element of the legal system, providing guidance, consistency, and precedent for legal interpretations and rulings. It is based on precedents, or the judicial decisions from previous cases, rather than laws based on constitutions, statutes, or regulations.
State law, on the other hand, is comprised of acts passed by the state legislature and signed by the state governor. In rare circumstances, the executive (President or governor) may refuse to sign the bill or reject it, which is known as a veto. When this happens, the legislature can override the veto with a two-thirds majority of votes.
The legislative history of a statute, which refers to the various documents created during a bill's progress through the legislature, can be very useful in determining a law's foundation and purpose. These documents include revisions, debates, hearings, and reports about the bill.
In summary, while case law is based on precedents set by judicial decisions, statutory law is comprised of written laws enacted by legislative bodies. Both play a significant role in shaping the legal system and ensuring its evolution.
