Case law, also known as common law, is the body of law created by judicial decisions. It is based on precedents, or the judicial decisions from previous cases, rather than law based on constitutions, statutes, or regulations. Case law is created when a higher court in a jurisdiction makes a decision and lower courts choose to adhere to the precedent set forth by that higher court's ruling. 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 judicial interpretations are distinguished from statutory law, which are codes enacted by legislative bodies, and regulatory law, which are established by executive agencies based on statutes. Case law helps fill in the gaps where statutes do not fully explain how the law applies to various situations, and it ensures consistency throughout the legal system.

What You'll Learn

Case law is created by the judicial branch
Case law, also known as common law, is the body of law created by the decisions and opinions of the judicial branch. It is a collection of reported cases that form the basis of the law within a given jurisdiction. Case law is based on precedents set by previous judicial decisions, rather than specific statutes or regulations. The Latin phrase stare decisis, meaning "let the decision stand", encapsulates the principle by which judges adhere to past decisions and interpret the law.
The judicial branch, through its courts, interprets and applies the law to specific cases. In doing so, they establish precedents that guide future decisions. These precedents are essential for maintaining consistency in the legal system. For example, in the United States, the decisions of the Supreme Court are binding on all lower courts, and these precedents have a significant impact on citizens' rights.
Case law is particularly important when statutes are ambiguous or incomplete. It helps fill in the gaps and provides guidance on how the law should be applied in different situations. This is evident in copyright law, where Congress may intentionally leave room for flexible, case-by-case interpretations. As courts review new disputes and issue decisions, case law evolves, and the law changes over time.
The process of creating case law involves several steps. A case typically starts at the trial court level, where evidence and witnesses are presented. If a party is unsatisfied with the trial court's decision, they can appeal to an appellate court. The appellate court does not re-examine the evidence but focuses on questions of law. If the appellate court's ruling establishes a new precedent or contradicts existing case law, it can set a new precedent of higher authority.
In summary, case law is created by the judicial branch through the process of interpreting and applying the law, setting precedents, and evolving the legal system through subsequent rulings. It is a dynamic and essential aspect of the common law system, ensuring that the law remains adaptable to new circumstances and societal changes.

It is based on precedents set by previous rulings
Case law, also known as common law, is the body of law created by judicial decisions. It is based on precedents set by previous rulings, which means that it relies on the judicial decisions and opinions of previous similar cases. When a court hears arguments, it will often refer to other rulings and court opinions regarding the law in question before issuing a decision. These existing rulings and precedents are collectively called case law.
Case law is created by the Judicial Branch, which interprets laws written by the legislative branch. After a bill is signed into law, it is tested in the courts. The courts have the power to interpret the law and rule on its constitutionality. Case law ensures consistency throughout the legal system, which is why the rulings of higher courts, such as the Supreme Court, are so important.
The principle of stare decisis, a Latin phrase meaning "let the decision stand", is the mechanism by which judges are bound to past decisions. Lower courts are generally bound by the decisions of higher courts in their jurisdiction. For example, in the US, a decision by the United States Supreme Court is binding precedent in all courts, and a decision by a Court of Appeals is binding on lower courts within its jurisdiction. However, a court does not have to stand by a previous decision if it is not a binding precedent.
Case law is particularly important when a statute is unclear or incomplete. In such cases, case law helps fill in the gaps and determine how the law applies to various situations. This is also known as "legislating from the bench", where judges appear to enact policy preferences with their decisions.

Case law is used to fill gaps in statutes
Case law, also known as common law, is a collection of reported cases that form the body of law within a given jurisdiction. It is primarily developed through judicial decisions and opinions rather than statutes. While statutes are written laws passed by legislatures, case law fills in the gaps by providing interpretations and applications of these statutes in specific situations.
Common law is deeply rooted in stare decisis, which means "to stand by things decided". This doctrine requires judges to follow the precedent established in previous similar cases. When a court hears arguments in a case, it will often refer to other rulings and court opinions to guide its decision. These precedents set by the judicial branch ensure consistency and stability in the legal system.
Case law is particularly important in unusual cases where the outcome cannot be determined based solely on existing statutes. In such situations, judges may refer to various types of persuasive authority, including legal encyclopedias and the published work of legal bodies. They will also consider the rulings and precedents set by higher courts, which are generally binding on lower courts. However, lower courts can choose to modify or deviate from these precedents if they are outdated or if the current case is substantially different.
The process of creating case law involves several stages. First, the facts of the case must be ascertained, followed by locating relevant statutes and previous cases. Then, the principles, analogies, and statements of various courts are analysed to determine how the next court is likely to rule. Finally, this reasoning is applied to the facts of the present case, and a decision is made. This decision then becomes part of the body of case law, which can be referred to and interpreted in future cases.

It is distinguished from statutory law
Case law, also known as common law, is a collection of reported cases that form the body of law within a given jurisdiction. It is based on judicial decisions from previous cases, also known as precedents, rather than law based on constitutions, statutes, or regulations. Case law is established by courts and involves the interpretation of statutes and constitutions.
Statutory law, on the other hand, refers to written laws that are passed by legislative bodies such as Congress, state legislatures, or the legislature in federal and state governments. These laws are prescribed in specific statutes and are adopted by society. The process of creating statutory law involves passing laws at different levels of government, such as local, state, and/or federal, and the specific process may vary depending on the jurisdiction.
Another key distinction is that statutory laws can be overturned under specific circumstances, such as if they are found to be unconstitutional. In contrast, case law is based on the principle of stare decisis, which means "let the decision stand". This principle requires judges to follow the precedent established in previous cases, and courts generally adhere to this principle by respecting and following the decisions of higher courts in their jurisdiction.
The role of case law also differs between civil and common law traditions. Common law courts provide detailed explanations of the legal rationale behind their decisions, citing previous relevant judgments and interpreting wider legal principles. These analyses create a binding precedent for other courts. In contrast, civil law jurisdictions' decisions are generally shorter, referring only to statutes, with the expectation that the reader can deduce the logic from the decision and the statutes.
In summary, case law and statutory law differ in their sources, creation, and application. Case law is established by courts and based on judicial decisions and interpretations, following the principle of stare decisis. Statutory law, on the other hand, is created by legislative bodies and enacted through specific statutes, with the possibility of being overturned under certain circumstances.

Case law can be applied to ongoing adjudication
Case law, also known as common law, is a law that is based on precedents set by previous judicial decisions rather than law based on constitutions, statutes, or regulations. It is the collection of reported cases that form the body of law within a given jurisdiction. In common law countries, including the US, UK, 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.
Case law is created by the judicial branch, which interprets laws written by the legislative branch. After a bill is signed into law, it is tested in the courts, which have the power to interpret the law and rule on its constitutionality. Case law ensures consistency throughout the legal system, with lower courts abiding by the precedents set by higher courts. For example, in the US, a decision by the US Supreme Court is binding precedent in all courts.
However, case law is not static, and courts can choose to overturn their precedent if they feel that developments or trends in legal reasoning render it unhelpful. For instance, 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. In such cases, a higher court may overrule previous case law by setting a new precedent of higher authority.
Case law is particularly important when statutes are unclear or undefined, as it helps fill in the gaps and determine the applicability and limits of a law. In some jurisdictions, case law can be applied to ongoing adjudication, such as criminal proceedings or family law. For example, in copyright law, Congress may intentionally leave the law undefined to allow for flexible, case-by-case application. As such, case law can be a powerful tool for attorneys to interpret the law and form arguments based on legal precedent.
