The difference between common law and statutory law is an important topic to understand as it helps citizens better understand their rights. Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is deeply rooted in stare decisis, which means to stand by things decided, where courts follow precedents established by previous decisions. Statutory laws, on the other hand, are written laws passed by the legislature and government of a country and are based on current statutes. These laws are developed by the government of a state or nation and are organized and codified into law codes. While common law is derived from judicial decisions, statutory laws have statutes as their basis.

Statutory laws are written laws passed by a country's legislature and government
Common law, on the other hand, is a body of unwritten laws based on legal precedents established by the courts. It is also known as "judge-made law" or case law. It consists of the rules of law that come from the written decisions of judges who hear and decide litigation (lawsuits). Judges are empowered to make these decisions by the constitution and statutes. When a judge decides a case and publishes a written decision, the decision becomes the precedent for future litigation.
The main difference between common law and statutory law is that common law is based on past judicial opinions, while statutory law is based on current statutes (written laws). Common law is deeply rooted in stare decisis ("to stand by things decided"), where courts follow precedents established by previous decisions. When a similar case has been resolved, courts typically align their reasoning with the precedent set in that decision.
Statutory laws are written laws that are passed by a country's legislature and government. They are based on statutes and are organised and codified into law codes. Statutory laws are developed by the government of a state or nation and cover all areas regulated by statutory laws exclusively, as well as those areas where common law is not applicable.
Understanding the differences between common law and statutory law is important for comprehending the legal system and one's rights. Both types of laws are followed by most nations in the world, and a combination of both is necessary for justice to be served.

Common law is unwritten and based on legal precedents set by past rulings
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by past rulings. It is deeply rooted in the principle of stare decisis, which means "to stand by things decided". This means that common law is based on the idea that courts should follow precedents established by previous judicial decisions. In other words, when a similar case has already been resolved, courts will typically align their reasoning with the precedent set in that previous decision.
The form of reasoning used in common law is known as casuistry or case-based reasoning. It draws from institutionalized opinions and interpretations from judicial authorities and public juries. Common law is not compiled into rules and statutes, but instead relies on precedent set by past rulings. The presiding judge over a case determines which precedents apply to that particular case.
When a case presents a legal issue that has never been decided by the governing jurisdiction, it is known as a ""case of first impression". In such cases, judges are empowered to resolve the issue and establish new precedents, as there is no controlling precedent or clear legislative guidance. Common law is flexible in this regard, allowing the law to be adapted to situations that were not contemplated at the time by the legislature.
Common law originated in the practices of the courts of the English kings following the Norman Conquest in 1066. It established a unified legal system across England, gradually replacing local folk courts and manorial courts. The doctrine of precedent developed during the 12th and 13th centuries, evolving from tradition, custom, and precedent. Today, common law continues to influence legal systems in various countries, including the US, UK, India, and Ghana.

Statutory laws are developed by the government of a state or nation
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is deeply rooted in stare decisis, which means "to stand by things decided". In other words, common law is derived from past judicial decisions and opinions, and these precedents are used to guide future rulings. For example, a judge may refer to similar past cases and use the judgments rendered then as a basis for deciding on a current case.
In contrast, statutory laws are written laws passed by the government of a state or nation. They are based on current statutes and are compiled and organised into law codes. Statutory laws cover all areas regulated exclusively by statutory laws, as well as areas where common law is not applicable. They are passed by federal and state governments, as well as various government agencies, and can include ordinances passed by towns and cities. For example, traffic laws, such as driving on a suspended license, or drug laws, such as those regarding drug possession, are statutory laws.
The United States Constitution is the supreme law of the land, and federal laws (statutes) enacted by the United States Congress must be followed by every state in the country. Federal laws cover areas such as the protection of migratory birds and the importation, interstate transportation, and sale of endangered animals. If a state law contradicts a federal law, the federal statute takes precedence.
State statutes are enacted by the state and apply to everyone within that state. They cannot violate the state constitution, the federal constitution, or federal law. State statutes provide the framework for various areas of law, such as animal law, and the state may delegate some of its authority to local units of government, such as counties and cities, to enact ordinances that govern specific issues.
Both common law and statutory laws are necessary for justice to be served. While common law allows for flexibility and the ability to adapt to new situations, statutory laws provide a clear and consistent set of written rules that are widely accepted by society.

Common law is also known as 'judge-made law'
Common law, also known as judge-made law, is a body of law primarily developed through judicial decisions rather than statutes. It is deeply rooted in stare decisis, which means "to stand by things decided", where courts adhere to precedents established by previous rulings. This is in contrast to statutory law, which is based on written laws or statutes.
Common law is derived from the practices of the courts of English kings following the Norman Conquest. It was originally considered "unwritten law" or "lex non scripta", and was widely believed to derive its authority from ancient Anglo-Saxon customs. Over time, as judges began to regard each other's decisions as binding precedent, a uniform system of law emerged across the country, giving rise to the term "common law".
As a result of this evolution, judges have been "making law" for hundreds of years, shaping the legal landscape through their rulings. This process is often referred to as "judge-made law". The term was first introduced by Jeremy Bentham as a critique of the legal profession's reliance on precedent.
In a common law system, judges play a pivotal role in interpreting and applying the law. When deciding a case, a judge will determine which precedents to apply, drawing on past judicial rulings in similar cases. This process ensures consistency and predictability in legal outcomes. However, in cases where no relevant precedent exists, judges are empowered to establish new precedents, contributing to the evolution of the law.
Common law, as judge-made law, has been a significant feature of the legal systems in many countries, particularly those with a history of English common law influence, such as the United States, India, Pakistan, and Bangladesh. It continues to shape legal practices and principles worldwide.

Statutory laws are based on current statutes
Statutory law, also known as written law, is a set of rules enacted by the government of a state or country. It is a codified set of laws that are passed on a local, state, or federal level. These laws are based on current statutes and are organised into law codes. They are developed by the government and passed by the legislature, which then become accepted by society. Statutes are the basis of statutory laws, and they cover all areas regulated exclusively by statutory laws, as well as areas where common law is not applicable.
Statutory laws are written laws that are easy to refer to and apply to specific cases. They are developed by the government and passed by the legislature, which then become accepted by society. These laws are based on current statutes and are applicable across a country or state. For example, federal laws in the United States are statutes enacted by the United States Congress and must be followed by every state in the country.
In contrast, common law is a body of unwritten laws based on legal precedents established by the courts. It is sometimes referred to as "judge-made" law, as it consists of rules derived from the written decisions of judges. Common law is deeply rooted in stare decisis, which means "to stand by things decided". It draws from past judicial opinions and interpretations from judicial authorities and public juries.
Common law guides court rulings when the outcome cannot be determined based on existing statutes or written rules of law. It is not compiled into rules and statutes but relies on precedent. Historical judicial rulings in past federal, state, or local court cases set the precedent for future cases. When a similar case has been resolved, courts typically follow the precedent set in that decision.
While common law and statutory law differ in their sources and application, both are necessary for serving justice and are followed by most nations worldwide.
